Question about 2002 Chevrolet Tahoe

1 Answer

I have a 2002 chevy tahoe and I just had an oxygen sensor replaced on monday the very next day my check engine light was back on. I had another diagnostic check and the said it was my oxygen sensor. It gave out the same reading heated oxygen sensor bank 2 sensor 2 but that was the same reading as the first sensor that I had replaced. My mechanic suggested at the time that I replace all of my sensors because the normally go 1 after the other.

Sound like either the mechanic didn't plug the sensor in all the way or you got a bad sensor, bank 2 should be the passenger side, sensor 2 is the sensor after the catalytic converter.

How to test oxygen sensor (s) 2002 chevy tracker?


The sulfur smell is because the 4 cyl is running rich . The issue can be the maf sensor or the 02 sensor going bad or the car needing a tune up. If the sensors are going bad there should be a check engine light on. Read the code for free at any parts store and then google the code they give you for more info on fixing the problem.

Some good news is the sulfur means the cat is functioning.

hope that puts you in the right direction

There is a fault with the inbuilt heater in the oxygen sensor, before the catalytic converter, on the exhaust pipe the same side of the engine as cylinder 1. The oxygen sensor has four wires within the cable sheath to the top of it. Two of the wires will share the same color. These wires supply power to an internal heating element wire within the sensor. Follow the cable from the oxygen sensor to the connector, you can do a lot testing here. Check the resistance between the two 'same coloured ' wires. The resistance is low, somewhere between 1 and 10 ohms. If there is no continuity (infinite resistance) then this is the fault and the sensor needs to be replaced. The codes: P0030 the oxygen sensor heater relay is at fault P0053 Oxygen heater resistance error P0135 Sensor 1 bank 1 error You are looking at replacement. A further confirmation take the connection from sensor 1 bank 1 and swap it with the sensor 1 bank 2 on the other side of the engine. The codes should 'transfer' and show P0036; P0059 and P0141.

Repair po145 code and po174 code on a 2002 chevy tahoe


With both codes pointing at Oxygen sensor readings being faulty, I'd get a can of electrical spray cleaner and spray clean the MAF sensor (mass air flow sensor) and have codes erased and see if they come back. Good chance a simple can of electrical spray cleaner will cure both codes.

Check Engine Light - O2 Sensor - bank 1 running lean


you should have three oxygen sensors on your car, one for each bank of three cylinders; should be towards the Y pipe on each exhaust manifold. Additionally you should have one on the exhaust pipe before the cadilitic converter.
