I have two check engine codes for my 1996 Plymouth grand voyager 3.3 engine. PO133 which they said was the Bank 1 sensor 1 and it was the 02 sensor on the header or exhaust manifold and PO140 which they said was the Bank 1 Sensor 2 and it was located after the catalytic converter.
I think I found the one after the catalytic converter but I cannot find the first one. Also, can you give me the chrystler part numbers for these?
Thanks, Rick
Pop the hood and look behind the engine in the middle....you'll see o2 sensor on the top of the exhaust pipe unplug it and remove it ............second o2 sensor is located on the same pipe under the passanger seat under the car
