General Motors has released a voluntary emissions recall for certain units of the GMC Savana van due to an issue related to the diesel particulate matter sensor.
The problem: affected vehicles equipped with the Duramax turbodiesel 2.8L I4 LWN engine may have a condition where the Engine Control Module (ECM) may not properly handle diagnostic information for the exhaust particulate matter (PM) sensor.
The hazards: if the ECM were to improperly handle PM data, then the PM sensor signal may be prevented from diagnosing the functionality of other components. In addition, if a PM sensor fault were to occur, then a diagnostic trouble code (DTC) or the malfunction indicator lamp (check engine light) may fail to illuminate.
The fix: certified GM technicians will be instructed to inspect affected vehicles and reprogram the ECM as needed. It should take techs roughly 30 minutes to perform the recall.
Affected components: ECM.
Number of affected vehicles: General Motors didn’t disclose how many vehicles are affected by this voluntary emissions recall.
Owners should: General Motors will notify owners of affected vehicles and instruct them to make an appointment with their local GM dealer.
