How long does it take to replace O2 sensor?
How long does it take to replace O2 sensor?
The rear 02 sensor takes about 10 minutes to replace on a bad day count on another 10 minutes to check/reset any codes in the engine computer. whole job should not be more than 1/2 hour.
Can a PCM replace an O2 sensor needlessly?
In my professional experience, the PCM is seldom the cause Nevertheless, they often get replaced needlessly But if the second shop arrives at the same diagnosis, it may be the exception to the rule. The O2 sensor produces it’s own voltage. The lower the voltage is the more oxygen there is in the exhaust gasses.
What does it mean when your PCM is not working?
The presence of fault codes means something else is wrong that needs to be diagnosed and repaired. So until the real problem is found and fixed, the PCM may not function normally. If the engine control system is not going into closed loop, chances are the coolant sensor or oxygen sensor are not working properly.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
How does the O2 sensor in a car work?
The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer.

Why is my O2 sensor still reading the same code?
If you have to drive 10 minutes before the Check Engine light comes on with the same code with the new O2 sensors, then the O2 sensor may be getting coated or contaminated where it can no longer read the oxygen content in the exhaust gasses and the voltage signal from the O2 sensor remains high.
