Hi, my mitsubishi has a P0141 code ( heater malfinction o2 sensor bank 1 sensor 2). I figured that at 80000 miles I might as well replace both the sensore at the manifold and the downstream one. After installation was completed and the code was cleared, the light came back on and had the same discrepancy. I figured that maybe the sensor was defective and returned it. Unfortunately, that didn't help. The car is still gerring decent gas mileage and runs fine. I suppose my question is why is the light still on? Thank you for your help and time.
have the same problem?
