Cel for all o2 sensors


350Chris

Recommended Posts

In the last couple of weeks, the car has started throwing cel lights with the fault codes referencing all o2 sensors.

 

One here and there owing to the berks I can expect but all on is one for investigation. I plan to get the car up on ramps tomorrow to check for a leak in the exhaust system or an obviously broken wire or sensor but can anyone shed any light on what this could be caused by?

 

Performance isn't down nor is the exhaust note

you prob need O2 spacers from Alex to keep sensor out of exhaust stream :pmzmanalex:

 

It has had the setup fitted for a long time - I would have expected it to throw codes consistently if it was that

 

Oh how wrong you could be :

 

Is it front or rear sensors that you are having the issue with?

I will put the description to them when I'm not posting from my phone

 

It would surprise me that it suddenly decides is wants o2 spacers having run with the exhaust setup for the 8+ months I've had the car plus the longer time that the previous owner had it

The codes that you have provided are all related to the rear sensors and not the front, so that narrows it down considerably.

 

Best to clear all the codes and start again as some may be archived.

 

You might find that the light may also stay off
