Gosman Posted January 2, 2017 Report Share Posted January 2, 2017 Hi,I'm about to connect both external Link MAP sensor 4Bar, and and Bosh IAT to the standard MAF connector on my EVO 4.This is how the MAF connector looks like,I have the stanard connector plug from map sensor so i got three different cables, which cable goes to which pin on the MAF connector? Also the IAT will come with two cables, which pin on the MAF connector? Quote Link to comment Share on other sites More sharing options...

Gosman Posted January 3, 2017 Author Report Share Posted January 3, 2017 Hi!Thank you so much for the picture, that's what i was looking for. I have this mapsensor and this connector cable, i don't have the wire scheme for that, could you make the same picture but with this mapsensor?

AGalecki Posted June 27, 2023 Report Share Posted June 27, 2023 Hello, I have this similar setup. I have a GM IAT sensor that is wired to pin 5/6 above. What do I select in the ECU to read for the ECU to use the temp sensor attached? Are there also settings used when I am on speed density vs MAF? I believe this fault is also causing my fan to run continuously. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 27, 2023 Report Share Posted June 27, 2023 MAF Pin 6 is AN Temp 2, set IAT source to AN Temp 2 and set the calibration to Delphi AC IAT. IAT or AN Temp 2 has nothing to do with your fan. Quote Link to comment Share on other sites More sharing options...

Jack m Posted May 5 Report Share Posted May 5 For some reason now it’s only reading -40 on the iat? Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 6 Report Share Posted May 6 That would suggest the input is at 5V - i.e it is open circuit - the ecu is not seeing any sensor connected to ANT2. This would suggest a wiring issue or the sensor is open circuit. You can test the sensor with a multimeter, it should be around 3000ohm at room temp.
