Ever since I've had my 2005 clio (mk2), the engine management light has been on. Bought it about 2 years ago. I use an OBD to clear the fault codes before MOTs but It always comes back on. So I decided I want to be rid of it. The fault code says it's something to do with the 02 sensor. So first...
Sorry if this is in the wrong section.
Does anyone know what reading the rear oxygen sensor should have? This is the one at the rear of the cat.
Basically, I’m getting a mil light based on the oxygen sensor. I’m wondering if I can possibly insert a resistor across the pins to fool the system...
