Bulletin Summary
Emission Recall. General Motors has decided to conduct a Voluntary Emission Recall involving certain vehicles. The Engine Control Module (ECM) may not clear the permanent status of DTC P0521 (Engine Oil Pressure Sensor Performance). If the ECM had previously set a DTC P0521 and the permanent status is not properly cleared, the vehicle may not pass certain Emissions Inspection/Maintenance (I/M) tests. Dealers are to reprogram the ECM.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
