Manufacturer summary

Original wording in English

Special Coverage Adjustment - certain vehicles, equipped with a 1.6L engine, may have a condition where cracks can develop in the diaphragm of the Positive Crankcase Ventilation (PCV) pressure regulator valve. This valve is a part of the engine camshaft cover. If this were to occur, excess air could be drawn into the engine intake. As a result, the engine may run rough, especially during idle, the Malfunction Indicator Light (Check Engine Light) would illuminate and a diagnostic trouble code for Fuel Trim Lean (P0171) or other airflow related DTC would set. Dealers are to replace the engine camshaft cover as necessary. The repairs will be made at no charge to the customer.
