Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.
The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle , hard starting, hesitation on acceleration, poor fuel economy, and stalling.
The EGR valve position (EVP) sensor can fail on this vehicle. The EVP sensor measures the EGR valve position and transmits the date to the engine control computer. If it fails, drivability and fuel economy can suffer, the Check Engine Light will commonly illuminate.
The engine may overheat at idle when the AC is on. A new, upgraded fan motor and resistor may be required to correct this concern.
