11 - IAT sensor error

Scroll Prev Top Next More

Intake temperature sensor open or shorted.

 

 

Most common issues and how to fix them

 

 

1. Check the wiring

clip0379

Check wiring. All IAT sensors are two wired, one pin to Sensor GND and the other to IAT (CMC1: F2) analog input of MaxxECU.

 

 

2. Make sure sensor is wired to Sensor GND, and not engine ground.

 

3. Check analog inputs (raw voltage)

Without no sensor connected, the IAT input voltage should be ~5v.
