Mightymetro Posted June 7, 2020 Report Share Posted June 7, 2020 I’ve finally cleared some of the error codes showing that was a bad lambda sensors and I’m now left with p0111 which is the air intake temperature it normally does it after about 10 minutes driving. if it was a short in the wiring I would have thought it would ping the EML straight away anyone had anything similar ?

steve930 Posted June 10, 2020 Report Share Posted June 10, 2020 Do you still have the EGR system installed & functioning, or has it been blanked off? Quote Link to comment Share on other sites More sharing options...
Mightymetro Posted June 11, 2020 Author Report Share Posted June 11, 2020 I think I still have it all working, I believe just the secondary air has been removed new faster reading intake sensor has arrived........but the light was reset and now won’t come back on 😂😂😂 Quote Link to comment Share on other sites More sharing options...
Mightymetro Posted June 28, 2020 Author Report Share Posted June 28, 2020 Bit more on this the EML kept pinging p0111 5/10 mins into driving so i changed the IAT sensor and then ended up with it lit permanently . I noticed the pins on the plug looked a bit corroded so I have replaced the plug with a new one and this cleared the code and it stayed off for the last 500 miles while running the engine in however, now I have started exploring more of the Rev range the EML will not light up but 5 seconds into a spirited run above 5000rpm and it comes on. Reset it and the same again, can drive around below this with no codes. As soon as I stretch her legs it pings on and still shows the code p0111 ive run the scan software and it shows min IAT at 36 degrees and max at 83 degrees. It won’t ever get above this due to the EML light coming on on reading the code using the V8 scan tool the freeze frame feature doesn’t seem to store the MAT and MAP values. My current thought is that I maybe have a earth related resistance problem and that the biter the intake temp the higher the resistance but then eventually it breaks down due to the corroded wire resistance. Does this sound at all logical Quote Link to comment Share on other sites More sharing options...
mike_sekinger Posted July 4, 2020 Report Share Posted July 4, 2020 You don't have any EGR or SAI fitted. The EGR manifold is blocked, but the temperature sensor should still be connected electrically. Since you are also experiencing modest boost, I would focus on the signal ground and resistance in the loom itself. Are you sure that the new sensor has the same characteristics as the stock sensor? I know that you also had the problem with the old sensor, but 83 deg seems awfully high for such modest boost.

sailorbob Posted July 4, 2020 Report Share Posted July 4, 2020 Is the IAT sensor showing the ambient air temperature when the engine is cold? If it's showing the 36 deg C you referred to then the sensor, wiring or ECU is faulty. Quote Link to comment Share on other sites More sharing options...
