Make: Cadillac | Model example: 2016 Escalade | Avg Mileage: 105787 | Job Number: 550434

Repair Issue:

Evap Monitor Does Not Run After Engine Control Module (ECM) DTC P0442 The Vent Solenoid Updated

Cause:

Evap Monitor Does Not Run After Engine Control Module (ECM) DTC P0442 The Vent Solenoid Updated

Customer Concern:

Engine Control Module (ECM) DTC P0442 The Vent solenoid was updated and repaired per GM bulletin 02-06-04-037I. Now the Evap Monitor will not run. The “Ambient Air Temperature” value on the scanner indicates 32°F. When the Ambient Temperature Sensor in front of the radiator is unplugged, then one thing that happens is the Rearview Mirror indicates “ICE”.

Test/Procedure:

1. Verify the IAT value as read on the scanner.
2. If erratic or incorrect, check the IAT at the Mass Air Flow (MAF) Sensor.
3. Perform the Service Bay Test to run the Monitor.

Tech Tip:

The Ambient Temperature Sensor in front of the radiator reports only to the Inside Rearview Mirror.
The Ambient Air Temperature on the ECM data list is a calculated value based on the Intake Air Temperature (IAT) Sensor and the Engine Coolant Temperature (ECT) Sensor.

Important Take-A-Way:

Tech Tip provides information related to the Ambient Temperature Sensor and points mechanics to related documentation that is helpful for diagnosing this specific repair.

Most Popular Fix:
