Need O2 sensors replaced. There asking $1,500
Is this worth the trouble or am i being scammed?

Hi there:
You might want to have a second opinion completed for your Dodge Durango air fuel mixture sensor replacement; as if they are simply replacing the O2 front and rear bank sensors; that’s a bit pricey.

As you can see above, your Durango has 4 O2 sensors. If one is in need of replacement, I would recommend replacing them all (they`re relatively inexpensive).
4 Oxygen Sensor for 2005 2006 2007 Dodge Ram 1500 4.7L Upstream + Downstream.
Hello, your oxygen sensors – 4 of them – are located before and after the catalytic converter on each exhaust pipe from each manifold.
The average cost for a Dodge Durango Oxygen Sensor Replacement is between $378 and $462.
Poor Engine Performance
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
V6 and V8 engines with dual exhaust have four oxygen sensors. A pair of O2 Sensors for each bank of the engine.
Definition — O2 Sensor
This package includes 4 sensors, 2 upstream sensors and 2 downstream sensors. But they keep the same, which means that they have no differences. Upstream location is between the catalytic converter and the engine; Downstream location is between the catalytic converter and the tailpipe.
Each oxygen sensor has its own unique characteristics specific to its application. One generic oxygen sensor that may appear to be the same cannot be used to replace a range of these specific oxygen sensors.
The oxygen or lambda sensor is one of the most important and one of the most misunderstood components of a modern fuel injection system.
Also known as the O2 sensor because O2 is the chemical formula for oxygen, the oxygen sensor monitors how much unburned oxygen is present in the exhaust as exhaust exits the engine. By monitoring oxygen levels, the sensor provides a means of measuring fuel mixture.
In most vehicles, replacing an oxygen sensor is a simple procedure that requires only a few tools. However, if this is not a task you are comfortable doing on your own, this is something that any professional technician, such as one from YourMechanic, can take care of quickly and easily.
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
There will be one in front of the catalytic converter and one in every exhaust manifold. Modern vehicles usually have at least four oxygen sensors placed at key points in the exhaust system.
Every catalytic converter is required to have a couple of oxygen sensors. So if you have a single exhaust system, you probably have one catalytic converter and, thus, two oxygen sensors. Cars with double exhaust pipes, meanwhile, will be fitted with a total of four oxygen sensors.

the most relevant questions and answers related to your specific issue
check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor
ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.
i need to replace both o2 sensors for vehicle listed above. so is it front left and back left o2 sensors?
ANSWER : Hi there:
Typically when an issue comes up with O2 sensors, it’s either the front bank (before the catalytic converter) or the rear bank (after). It’s very rare that all need to be replaced. However, the quickest and most effective way to determine which is faulty and need to be replaced is to have one of our professional mechanics complete a check engine light is on inspection. This service will allow them to determine which one is bad, and if you’d like, we can replace that O2 sensor for you.
Check Engine light comes on, mechanic replaced o2 sensor but light still comes on.
ANSWER : Hi there:
If the mechanic completed the O2 sensor replacement, reset the codes and the error code was triggered again, it is possible that the catalytic converter is damaged and needs to be replaced. However, it’s also very common for the electrical harnesses that power these sensors to become frayed, damaged or faulty; which can also trigger the check engine light. It’s not advisable to drive a vehicle with a damaged catalytic converter for extended periods of time, as it can cause damage to internal engine components.
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 have a p0171 code on my ford ranger 2.5 and have replaced fuel filter maf sensor, iac sensor, fixed vacuum leaks, replaced fuel
ANSWER : Hello there. You might to read this article about the P0171 OBD-II trouble code; as it will give you ideas on causes and possible solutions.
Need to replace Accelerator Pedal Position Sensor
ANSWER : The TPS and a scanner to test it is all that you need. The code P0122 points to the sensor but a through pinpoint test should be done to make sure the sensor is failing before you replace it.
If you need help with this, contact a certified mechanic who can diagnose your Check Engine Light code and make the necessary repairs to your vehicle.
Car won’t accelerate past 25 mph and makes deep noise when you try too replaced o2 sensor maf sensor/ throttle body does rattle
ANSWER : Hi there. It is quite possible that your car has entered what we call a fail safe or "limp mode" due to an error code being activated and stored in the ECU. This will occur when the ECU or a sensor detects a mechanical or electrical fault on one or several fuel, ignition, cooling or powertrain systems. It’s designed to allow you to safely "limp" your car to a repair facility or home so a professional mobile mechanic can complete a car is slow to accelerate inspection and determine the right course of action. It is also possible that this issue is caused by a loose vacuum line or other component like the throttle position sensor.
So I had two codes come up for two of my o2 sensors..replaced them both and check engine light is still on…my mechanic seems to
ANSWER : Hi there:
Although it’s hard to say if there was serious damage done to your ECM during this service, it’s more likely that the stored error codes were never cleared from the ECM, and that’s why the warning lights still appear. This is a common oversight with some mechanics, but if you have a mobile mechanic complete a check engine light inspection, they should be able to clear those stored codes and determine if further damage has occurred.
