I recently had an engine management light up, i plugged it in and it says O2 sensor & O2 sensor heater.

I replace the O2 Lambda sensor and it was fine for 2 - 3 days and now its come up again with the same fault, the lambda was brand new!

Any ideas anyone? Does anyone know if the heater is built in to this one as its a 5 pin Lambda?

hi mate, just a quick question, did the EPC light come on for the sensor, or was it the 'check' light ?

No the EPC light did'nt come up just the Check light, im gonna try spark plugs tommorow as i read on here, someone tried that, like i say its strange as i replaced the Lambda! I may take it back and get another one, but think its unlikely to be that!
