Defect
The EGR pressure sensor installed in the exhaust gas recirculation (EGR) system has insufficient resistance to exhaust gas. Corrosion from exhaust gas causes the sensor to produce abnormal output, leading to a warning light illuminating and poor acceleration. In the worst case, the engine may fail to start.
Corrective action
On all vehicles, replace the EGR pressure sensor with a corrected/revised part and reprogram the engine control unit with the corrected/updated software.
