Retired to the country
4.6 petrol.
I am getting a persistent error code P0112 which points to the air temp sensor in the MAF. I have checked for air leaks in the induction pipe and that's all OK. I have cleaned the connector with switch cleaner no difference. If I take the air box cover off and just rev the engine the code doesn't re appear. If I put it back its straight away back.
Is there anyway of testing the sensor with a multimeter?
If it is knackered are the cheaper replacements any good or do I need to get a genuine Bosch one?

Could you be nudging a connection/wire somewhere? Genuine MAF seems to be the way to go, they are quite fussy

I did wonder that, but guess where the wire disappears, under the upper manifold
It seems to run OK, no errors on the dash etc. Needs a new air filter which I will pick up tomorrow. I have got the gas running better, not 100% but very drivable. Plug colours are all golden so mixture can't be far off.

If it's OK with the airbox cover off, could it be that the air filter is blocked?
 
I'd check the filter box where the air also enters, mice can build a great nest that can course issues like this also. I've had a Honda civic 1.6 idic' diesel in with an air/fuel mixture sensor fault....

Looks like it's had regular dealer servicing:rolleyes:

Funny you should say that... They had bought it from a car dealer who had serviced it.... The oil filter (after being driven from England) was loose if they skimp on an air filter what else could be a foot!!!
 
So have checked all the intake for blockages but all clear, new air filter fitted and a known good MAF as well. Unfortunately the issue still exists so looks like a wire somewhere in the loom is busted. Just got to work out where the wires go now.
