Engine light

petelazro · 11-16-2014, 12:08 PM

Hi Guys,

I scanned my car and got a P014A code reading "02 sensor delayed response - rich to lean"

I cleared the code and it has gone away. I will see if it stays off when i take it for a drive. The car drives the same and doesn't feel any different.

thanks in advance

*UPDATE* drove over 200KM and warning light is still off? am i safe?

Unless you have an exhaust leak, or maybe even an extreme vacuum leak, then you may need a new set of O2 sensors. Don't worry, if there's a problem the code will come back.

thanks.. today the CEL came back on and i scanned it and got p0160 code

so initially p014a - ( the program said "o2 sensor delayed response- Rich to lean-Bank 2 Sensor 2)

and now

p0160 - 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)(the program said "no activity"

i assume its the sensor itself and not an exhaust leak since there is no activity detected. also can i get away without changing it for a while since its a post cat sensor?

I would check to see if the sensor is plugged in fully, and that the wiring is well insulated. If that isn't it you are looking at replacement, but O2 sensor failure isn't common.
