Hi
anyone had this code? I have replaced the IAT sensor in the intake hose, immediately the engine light went off & I thought 'great, a cheap fix', approx 50km later, the light is back on.
It seems to come on initially when the van is idling, almost as though the air temperature when not under pressure into the air intake warms up hence the high temp reading.
then goes on and off probably twice in a day's driving so seems tpo be an intermittant fault somewhere.
any thoughts?
thanks

The PCM is receiving a higher than expected voltage signal from the IAT sensor. When the vehicle is cold, (after setting over night), before you start it, check the ECT, (Engine Coolant Temperature), sensor and the IAT, (Inlet Air Temperature) sensor. They should both indicate the same temperature. Post your results.
