Sorry thought you were telling me about the IAT.
Been intouch with local dealer. The IAT sensor is no longer sold, but got the part# 90499898, ECT sensor is no longer available also got part# 90411977.
There are two radiator fan switches on the system, one is £45+VAT the other is £25+VAT. One starts with code WM the other is XC so need to remove my sensor for the code.
Thermostat is £43.75+Vat.
What Manufacturer would you recommend for ECT sensor and IAT?
Spoke to a O2 specialist, to see what they can suggest along with your help.
This is their reply.
Both HC and Lambda are too high. This normally means a misfire
CO is high because catalyser isn't oxidising it to make CO2. This is normally accompanied with Low lambda reading, but yours has the opposite to this which is unusual. HC is usually too high because the catalyser has run out so to speak of O2, but the high lambda (excess osygen) reading disputes this. Something's very wrong at any rate
If the engine's been rebuilt and it seems low on power, is the valve timing correct? You'd be surprised how many engines i've seen that will still run fine after having skipped a tooth. If there's a problem check the timing belt is the correct one, i've had a belt with one too many teeth supplied to me before by GSF but they swore it was the correct one
If all that's ok then start looking at the engine management system.
