Hello...
Engine management light flashed on intermittently a bit today on a trip to town. Didn't come on on the way back, but decided to read my fault codes to see what's up.
Got 13 - Oxygen sensor - No change in voltage/open circuit.
And 38 - Oxygen sensor - Voltage low (1990 model year on).
No other codes.
I guess this means an oxygen sensor is on it's way out?? I also have an annoying rattle from the exhaust that can be heard outside the car - dunno if this is a symptom (maybe cat breaking up) or maybe what is causing the oxygen sensor to fail in the first place? Anyway - from those fault codes how do I tell which sensor it is? Any ideas on a cheap source for a replacement - used but working is fine by me!
Cheers
Liam
