Thanks very much Dal. I thought it might be a sensor issue (in fact every issue I have had with any car and a warning light has been down to the damn sensors failing! Rather ironic isn’t it).
I was surprised he couldn’t tell me what the P3302 code meant at the time (I thought the scanners gave you a one line explanation of the code), but he has made a phone call to somewhere and will call me when he gets an answer). Are there any places of reference for theses codes - the ones I have found so far on the internet only go up to codes around P1918?
If the sensor needs replacement, is it something you can tackle yourself? Is it a simple task of removal and refitting? I have seen on the forum that you can test the sensors with a multimeter by removal and then checking across the connectors for open circuit to find the faulty one, is that correct?
Sorry about the barrage of questions, it just that I am on a miniscule budget and with xmas and a recession looming, I am keen to keep my expense down to an absolute minimum. Thanks so much.
