CID 0105 FMI 04 Inlet Manifold Temp Sensor short to ground
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects a signal voltage from the inlet air temperature sensor that is less than 0.2 volts.
System Response:
The ECM flags inlet air temperature as invalid data and a default value of −40 °C (−40 °F) is used.
- Hard starting
- Low power
Test Step 1. Perform the following diagnostic procedure: Engine Sensor Open/Short Circuit - Test
Results:
- OK - STOP
