When I accelerate it has no power. It only goes slowly. I have a code PO700 that has came up.

My car takes off really slow than builds up speed it showing a code PO700 would that be a transmission speed sensor output or input

My car has 85000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello. Code P0700 is the trouble code for an issue with the vehicle’s transmission control system. If the computer detects an issue within the transmission control system it will set off the Check Engine Light in order to alert the driver of the issue. This code is a general code, and will usually come accompanied with other, more specific, transmission related codes.

A few possible causes are issues with shift solenoids, issues with the transmission valve body, an open or short in the wiring, or a faulty transmission control module. It may also be possible that the issue is related to the speed sensors, though usually that would set off a specific trouble code indicating so.

As the code and symptoms that are present can be caused by a wide variety of issues, I would recommend a professional technician, such as one from YourMechanic, come to your location to diagnose the transmission and acceleration issues.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
Slow acceleration can be caused by a number of different things, including a problem with the oxygen sensor, the airflow meter, or the throttle position sensor. Your check engine light may also come on if there is a problem with the acceleration. Engine speed sensors may also be another factor.
Error code P0700 signifies that a malfunction has been detected in your vehicle`s transmission controls. Most modern automobiles feature a specific control module as it relates to the vehicle`s automatic transmission. This module is known as the Transmission Control Module (TCM).
It could be due to a problem with the timing belt, the spark plugs, or the fuel injectors. It could also be because you have a dirty air filter or a clogged fuel filter. The fuel system may also be low on fuel. The accelerator pedal may also be sticking.
When you press down the accelerator pedal and get minimal output, it could mean you have a problem with your fuel system. The most probable issue is a clogged fuel filter. Your fuel filter works to ensure that dirt and debris do not get into the fuel system.
The Quick Fix:

Clean air filters and fuel injectors will reduce the strain on your car. An engaged emergency brake causes the brake to drag slowing down your car. Disengage the brake to solve this issue. Sometimes acceleration problems are just because of low fuel or poor quality of fuel.

The OBD-II scanner error code P0700 problem is a generic code that applies to vehicles equipped with OBD-II. It refers to the transmission control module (TCM) in the automatic transmission.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
A P0705 code stands for “Transmission Range Sensor Circuit Malfunction (PRNDL Input).” This code is a generic powertrain code that can display in certain vehicles built in 1996 and onward.
What does OBD-II fault code P07A5 mean? The Hybrid Control Module monitors the transmission clutch for proper operation. If the Control Module detects the clutch is not releasing as commanded, code P07A5 will be set.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
Worn Transmission Fluid (Automatic Transmission)

Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.

The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
Common Causes of a Failing or Degraded Engine

Low Compression. Dirty or Clogged Air Filter. Dirty or Clogged Fuel Filter. Bad Fuel Injectors.

The accelerator pedal sensor transmits the position of the accelerator pedal to the engine control unit. Based on this information, the load requested by the driver can be implemented immediately.
An accelerometer sensor is a tool that measures the acceleration of any body or object in its instantaneous rest frame. It is not a coordinate acceleration. Accelerometer sensors are used in many ways, such as in many electronic devices, smartphones, and wearable devices, etc.
The catalytic converter helps with the airflow into the engine by allowing exhaust gases through. If the catalytic converter gets clogged, the airflow to the engine is compromised, and you will find your vehicle`s acceleration sluggish.
Rough starts, hesitation and poor acceleration are all common symptoms of a bad spark plug. If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle.
The TCM fuse is in the main fuse block and is probably 10 amps. If the fuse is blown, that is confirmation but the faulty fuse means there is a short circuit in the TCM and/or wiring that would have to be traced and repaired.
Error code U0140 is associated with the Body Control Module (BCM) or the wires from the Engine Control Module (ECM) to the BCM. The BCM is part of your car`s electrical system. It controls various functions, including the tire pressure monitor, door locks, keyless entry and anti-theft systems.
There are several causes for your car to lose power significantly while accelerating. The most typical causes of a car not accelerating while driving include a faulty sensor, contaminated fuel or air filters, or a faulty timing belt.
Culprits include a dirty fuel filter, clogged fuel tank strainer, clogged or failing fuel injectors, or a defective fuel pump. On most vehicles replacing the fuel filter is a DIY operation.
This hesitation while accelerating can be the result of a number of issues, including something like a clogged fuel filter or even a broken fuel pump. Sometimes, something could also be wrong with the transmission.

my car is slow to accelerate. i have a p0171 code. i replaced my o2 sensor but the code came back on. what else could it be?
ANSWER : The code P0171 is a lean code indicating the O2 sensor is detecting the engine is running lean – that is, the air/fuel mixture is imbalanced. You may have a clogged fuel filter or a fuel pump that is not supplying enough fuel pressure. You will need to have the fuel pressure and volume checked with a fuel pressure gauge. You can try to replace the fuel filter to see if it helps first. Your best thing to do is to have a mechanic diagnose the problem and check the fuel pressures and filter. Also make sure your air filter is clean and the inlet air tube is not cracked or loose.

Check these items, and if you still need assistance, contact a professional mechanic. A certified mobile mechanic from YourMechanic can visit your home or office to inspect your vehicle’s acceleration issues.

Diagnostic code read o2 sensor bad, replaced o2 sensor, cleared code but engine light came back on, is it caused by bad air filter
ANSWER : Hello there. Typically jump starting a vehicle doesn’t trigger an OBD-II error code. However, one of the most common misdiagnosis issues with the P-2270 is replacing the O2 sensor before diagnosing if there are any exhaust leaks. Obviously, you’ll want to check for the exhaust leaks first, repair the damaged component, and then clear the codes before scanning the vehicle again. Sometimes the electrical harness attached to the O2 sensor is damaged or dirty which will also trigger this error code. The noise and vibration may be an indicator of a loose exhaust pipe, which may be the source of the error code staying on. If you need any help, have a technician from YourMechanic come to your home or office to diagnose your Check Engine Light and make the necessary repairs.

I had my ECS replaceed and my TPS and the code for TPS was gone but the ECS code came on after 5 miles is it possible the new one
ANSWER : There is a possibility the new module is faulty, but there may be something else going on with the car as well. Wiring can be an issue with these vehicle so consider hiring an experienced technician like one from YourMechanic to loo at the car and offer a personal diagnosis. You can have bad knock sensors offering false readings or some faulted wiring.

trouble codes PO101
ANSWER : Hi there. There are 5 things that can cause the engine light code P0101 to come on. The mass air flow sensor (MAF) could be dirty, the MAF could have failed, the air intake could have a leak, there could be a break in the wiring on the MAF or a loose connection, or the catalytic converter could be plugged up. First, check the wiring harness to the MAF and make sure that it’s tight. Then check all of the intake hose plumbing and make sure that they are all secured tight. If those are in good shape, then remove the MAF and clean it with a non-chlorinated electrical cleaner. Then put it back on and see if the engine light goes out. If the light is still on, check the harness for power with the engine running. If there is power, then hook up the harness to the sensor and back probe the wiring with a tiny paper clip and check for power coming out of the sensor. If there is no power coming out of the sensor, then the sensor is not working and needs replaced. If there is power coming out of the sensor, then check the exhaust system for a plugged catalytic converter. Place something flat against the exhaust pipe with gloves on and check to see if there is a pressure build-up. If there is no pressure, then the catalytic converter is plugged. If there is pressure and everything checks out to be good, then the computer may have a bad connection and needs to be replaced or fixed. Most likely the sensor is not working or there is an air leak. If you need further assistance with diagnosing your MAF, then seek out a professional, such as one from Your Mechanic, to help you.

Jerky acceleration above 3000rpm no trouble codes
ANSWER : Hello there, thanks for writing in. 115,000 miles is about the right time to change the clutch in a manual transmission vehicle. This may explain the jerky motions above 3000 RPMs while the engine is making more power, and may be the reason there are no codes for the problem. Have an experienced technician also inspect the ignition and fuel delivery systems for any faults in order to diagnose your jerky acceleration issue.

Wrench light came on truck has no power and the rpms constantly get higher if put in park
ANSWER : Hi there:

The wrench light is service light indicator that alerts the driver that maintenance or service is due for a component. Most of the time, scan that Auto Zone will complete uses a basic scan tool, which does not factor or is unable to download all stored codes in the ECU. Anytime the vehicle goes into limp mode, an error has been detected inside the transmission or with one of the electrical sensors or components that are critical elements of the transmission system. It’s probably a good idea to have a professional mobile mechanic complete a check engine light is on inspection; even if the light is not activated, any stored codes caused by the transmission limp mode activation will be accessible and should pinpoint the source of your Ford Super Duty’s issues.

Why do I keep getting a P0101 code in my 2011 Nissan Sentra
ANSWER : Hello. If you are continuing to get the same code then the engine needs to be checked first for any vacuum leaks. The slightest leak in the intake tubes or any of the vacuum hoses or gaskets will cause this. I usually will do a smoke test to find the issue. If there are no leaks then you may have a defective sensor. I do not like to use re-manufactured MAF sensors. If the sensor is known to be good then it may be a circuit issue, which is rare on this vehicle. If you need help with this, consider YourMechanic, as a certified mechanic can come to you to [diagnose why the check engine light continues to come on] https://www.yourmechanic.com/services/check-engine-light-is-on-inspection
