Justthejedi Posted December 16, 2017 Share Posted December 16, 2017 So my engine light is on with fault code P2A00. O2 sensor bank 1 sensor 1. Had my exhaust checked for leaks and found slight leaks on both sides where the cat bracket meets the exhaust bracket due to them being quite rusty so filled the gaps with silicone and turned light off. Could this throw up the engine light? Or is the sensor faulty and need replacing? Anybody know which side the fault is referring too?

HEADPHONES Posted December 17, 2017 Share Posted December 17, 2017 https://youtu.be/fl7ON1wnUlM Use the pedal dance above to delete and reset the ecu warning light. O2 sensor has thrown a wobbler about 5 or 6 times on my zed over the past 10 years. Luckily it's just been a glitch and runs fine for years before arising again. Obviously if the reset doesn't work there may be an underlying problem that needs fixing before the light will go out without returning.

nissanjuke Posted December 18, 2017 Share Posted December 18, 2017 yes I agree with above or just clear it with a OBD reader. Quote Link to comment Share on other sites More sharing options...
Justthejedi Posted December 18, 2017 Author Share Posted December 18, 2017 Yeah, I've cleared it with my reader. I'm going to order a couple of Berks gaskets, hopefully that will cure the exhaust leak and stop sending the o2 sensor loopy! Quote Link to comment Share on other sites More sharing options...
