Can a error saying Manifold Absolute Pressure/ Barometric Pressure Circuit Malfunction be caused by a almost dead battery?
A error is continually popping up and my inspection and I can't figure it out. I've put in several map sensors. Check engine light keeps appearing on after shutting off. After driving a few miles when I go back to garage, there are always 2 uncompleted but no Map error. When I drive a few more miles the check engine light comes back on and the Map error is back. Could a almost dead battery cause this error?
My car has 185152 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello. The low battery should not cause problem with the MAP sensor but will cause the computer to have different issues. It could cause the charging system to overcharge. You need to verify that the intake does not have any cracks or air leaks between the MAF and throttle body. If you would like to have the Check Engine Light diagnosed and addressed properly, a certified professional from YourMechanic can come to your car’s location to inspect the car and guide you through repairs.

DTC P0106 is a generic diagnostic trouble code related to the manifold absolute pressure sensor (also called the MAP sensor, Barometric Pressure Sensor, or Baro sensor.) It indicates that your MAP circuit is suffering from an incorrect voltage output range or that there`s an engine performance issue.
P0106 is a diagnostic trouble code (DTC) for “Manifold Air Pressure (MAP) Barometric Pressure Sensor Electric Circuit Output Range and Performance Problem“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
The meaning of fault code P0107
Trouble code P0107 indicates that the manifold absolute pressure (MAP) sensor`s voltage input is too low. The sensor is a resistor which responds to changes in the manifold pressure, affecting the resistance of the device and its voltage signal.
Check the MAF sensor and clean it out with dry air. Then put it on and disconnect the battery for 12 minutes and hook it up. This will clear the computer to want to relearn itself. Then drive the vehicle and see what happens.
Like most electric sensors, MAP sensors are sensitive to contamination. If the map sensor uses a hose, the hose can become clogged or leak and unable to read pressure changes. In some cases, extreme vibrations from driving can loosen its connections and cause external damage.
It will also cause hesitation on acceleration and general poor engine running, and excessive fuel consumption. Therefore, it`s crucial to identify the problem as soon as possible, as driving the vehicle with this issue may cause engine damage.
you start getting worse fuel economy: in some cars, a failed map sensor will cause the engine`s computer to default to a safer, rich fuel mixture. this will decrease your fuel economy. 5. your car surges and dies out: a faulty map sensor can cause engine rpm to fluctuate or surge, primarily at idle or low speeds.
Why do MAP sensors fail? Like most electric sensors, MAP sensors are sensitive to contamination. If the map sensor uses a hose, the hose can become clogged or leak and unable to read pressure changes. In some cases, extreme vibrations from driving can loosen its connections and cause external damage.
No, it is also dependent on throttle position. If you are going uphill at 50% throttle at 3000 rpm you`re burning a lot more fuel than you are coasting downhill at the same speed and engine speed.
To remove the old sensor, first disconnect the negative battery cable. This will ensure that the car is not damaged when the sensor is removed, and will also reset the vehicle`s computer and trouble codes.
Common P0420/P0421 Symptoms
Other items that could be causing multiple trouble codes to appear with the 420/421 codes are: Bad Oxygen Sensors (either upstream or down) Engine Rich / Lean condition. Bad MAP or MAF sensor.
What are some differences between a MAP and MAF sensor? While a MAF sensor is always located before the throttle body, a MAP sensor can usually be found attached to the intake manifold. Because it is in the intake tract, A MAF sensor will also have its own housing (usually plastic) to hold it in place.
The manifold absolute pressure sensor (MAP sensor) works with intake air pressure to define proper air and fuel quantities required for the ignition cylinders. The MAP sensor measures the vacuum of the intake manifold, which fluctuates according to engine load, relative to the barometric pressure.
The thing is, a bad MAP sensor won`t always trigger a check engine light or cause the computer to register a DTC (diagnostic trouble code).
A dirty air filter can cause your vehicle to throw a Check Engine code. During this instance, the Check Engine Light of your vehicle will turn on. The light turns on because your vehicle is sensing that its engine isn`t receiving enough air.

Denatured alcohol should be avoided for this reason. Mass airflow sensors must be delicately wiped with clean high-grade tissue to reduce scratches, and one should always avoid scrubbing as this may break parts or otherwise cause damage.
DIY sensor cleaning is completely safe. As long as you do it the right way, you shouldn`t have any problems. Many photographers regularly do their own sensor cleaning without any issues.
Over time, it can get dirty and increase fuel consumption, cause a jerking during acceleration, and even stall your vehicle after ignition. If you think you need to clean your MAP sensor, you need to remove it and then give it a spray and scrub.
Common signs include poor engine performance, like sluggish acceleration, lack of power, and misfires, as well as the Check Engine Light turning on.
MAP sensors contain no moving parts, and they don`t typically wear out, but cleaning the MAP sensor may be required if it`s contaminated by carbon or other deposits from the engine. If voltage is slow to respond to pressure changes, contamination could be responsible.
A faulty Map Sensor can cause a vehicle to run rich or lean, which will affect the vehicle`s ignition timing and cause the engine not to run smoothly.
An idle air control valve, also called an idle air sensor control motor, is an electrically operated valve that controls the amount of air that bypasses the throttle plate in cars with a fuel injection system [source: Autozone]. This causes the idling speed of the engine to change as needed.
Yes a MAP sensor can cause this problem. The sensor controls how much load is on the engine and will cause the rich running condition. I have never known one that can be cleaned and fix the problem.

Battery dead truck wont start after alarm being messed with.
ANSWER : With all the playing around, the battery going dead more than once, and it being over 5 years old, I would try replacing the battery first.
After the battery is replaced, lock all the doors and then unlock the vehicle with a remote or door keypad if you have one equipped. Next, using an original key, see if it will start. If it doesn’t then the vehicle may have locked you out. In this case, only a WDS scan tester at a dealer can regain access to the passive anti-theft system for you. Unfortunately this would mean that you’ll need to tow it to a dealer.
If you decide to get this fixed or would like a second opinion on this, get the car looked at by a qualified technician, such as one from YourMechanic. A mechanic can perform these checks to properly diagnose your dead battery and fix it accordingly.
2011 Nissan will not crank and the battery goes dead after one year.
ANSWER : Hi there. The battery is the remote key fob will only last about 8 years. Since it is now 2017, the battery is now 8 years old and could have lost its charge. The chip in the key tells the computer (ECM) to start the car. If the vehicle continues to eat away the battery in the key fob, then either a button is stuck on the key fob or there is a parasitic load (something that is on that is to be off) in the car causing the key fob to drain the power as the engine is running. If you need further assistance with your car not starting, then seek out a professional, such as one from Your Mechanic, to help you.
Has new alternator, new battery when started , motor dies when battery is disconnected…my mechanics are stumped on this
ANSWER : Hello.
If replacing those particular components did not correct the issue then the next thing I would look at is the vehicle’s voltage regulator. It appears that this engine’s electrical system is equipped with an external voltage regulator that functions, or malfunctions, independently of the alternator. The voltage regulator regulates power from the vehicle’s alternator, and can cause issues with the electrical system when it malfunctions. I would test it to see if it is functioning properly. It is a silver box that should be mounted somewhere in the engine bay, usually on a wheel well. A technician from YourMechanic can come to your home or office to replace your car’s voltage regulator if necessary.

Can a bad pressure switch cause back pressure, enough to blow the pressure line?
ANSWER : Hello. In most cases a pressure switch can cause pressure to build up if it malfunctions, however that depends on the type of pressure switch and what system it is for. If you are referring to the cooling system then it may be possible that there is an issue with the cap that is not releasing properly, or possibly an obstruction in the cooling system, such as a thermostat that is stuck closed. It may also be possible that overheating is what caused the pressure to blow the line, however a proper diagnosis would be required to determine if that might be the case. As it appears that you could possibly be experiencing cooling system issues, if the problem persists I would recommend having a professional technician, such as one from YourMechanic, visit your location to determine what may be causing the issue.
Battery went dead. Replaced battery. Engine and battery lights are on.
ANSWER : Hi There,
As you know, your problem may be related to a faulty alternator resulting from it not properly charging the battery. This may also be related to a faulty voltage regulator. The voltage regulator regulates the rate at which the alternator charges the battery. When this is not working properly, this may allow the alternator to over or under charge the battery, in either case resulting in the battery failing prematurely. I would recommend having an expert from YourMechanic come to your location to diagnose your charging system.

Dead battery jump-started, but no causes found. 2014 Buick Verano
ANSWER : Hey there, thanks for writing in about your 2014 Buick Verano. This could potentially be a charging system problem. As you may already know, your car has an onboard charging system called an alternator which works to keep your battery charged at all times. If this is not working properly, your battery will not stay charged. The fact that your battery took a new charge and stayed charged suggests that the battery is not the problem. If the problem comes back and persists, have an expert mechanic, like one from YourMechanic, inspect your charging system to pinpoint any faults.
Autozone says the camshaft timing is "over retarded" and this is causing the engine light to be illuminated.
ANSWER : Try changing the engine oil and filter to a good type of oil and filter. This will help with the VCM system and keep it functioning properly. If the VCM continues to act up and cause the engine oil pressure to drop, then I recommend seeking out a professional, such as one from Your Mechanic, to help you.
