Getting code pc0141 service emmisions system


deville92

Recommended Posts


I am getting the code pc0141 on my 1996 deville. I wanted to know what o2 sensor I will need?

P0141 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 2

Here is the O2 Sensor Location Key:

Bank 1 Sensor 1 - right bank (rear) manifold

Bank 1 Sensor 2 - pre-cat

Bank 1 Sensor 3 - aft-cat

Bank 2 Sensor 1 - left bank (front) manifold

Pre-1995 - DTC codes OBD1  >>

1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm

IF PC0141 translates directly to P0141, you are looking at the bank 1 sensor 2 position which is located directly in front of the catalytic converter.

The reason for the IF is the transition from OBD to OBDII codes that was mandated effective 1/1/1996. I'll bet the "build date" on your driver's door sticker shows a date in 1995.

I don't have an OBD I code ending in 141. I think that "PC" is short for "PCM." My money is on the HO2 sensor at the front of the cat.

If the "Service Engine Soon" light is on, it's P0141. If the "Traction Control" or "ABS" light -- or both -- are on, it's C0141. But, deville1996 already knows it's P0141.

The oxygen sensors on the cat are relatively easy to change. You can put the car on a rack and get at them from under the car.
