Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects all of the following conditions:
- Either the duty cycle is greater than 95 percent or less than 5 percent for one second, or the sensor frequency is greater than 1000 Hz or less than 150 Hz for two seconds.
- There are no active diagnostic codes for the digital sensor supply (8 Volt DC).
- The ECM has been powered for at least three seconds.
System Response:
The ECM will log the diagnostic code. The auxiliary temperature will be set to a default value.
- None
Test Step 1. Perform the following diagnostic procedure: Auxiliary Temperature Sensor Circuit – Test
Results:
- OK – STOP
