Known Problems

The anti-lock brake (ABS) warning light may illuminate due to an internal fault with the ABS hydraulic valve assembly. Our technicians tell us that replacement of the hydraulic valve assembly will be necessary to correct this concern.

The passages for the Exhaust Gas Recirculation (EGR) system can become restricted or clogged causing the Check Engine Light to illuminate. The EGR valve will need to be inspected and the passages cleaned.

Vehicles with a V6 engine may develop an engine misfire under load (acceleration). This can be caused by a valve cover gasket leaking oil into a spark plug well, shorting the spark plug to the cylinder head. To repair this concern, the valve cover needs to be resealed and the spark plugs and wires should be replaced.

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

The Check Engine Light may come on and the engine will run poorly. During diagnosis the technician may find a trouble code for the Camshaft Position Sensor (CMP), P0340. It is recommended to check the CMP driveshaft for looseness in the housing because if the shaft is loose, a new sensor will be damaged again. If the shaft has play, the CMP sensor and housing unit will need to be replaced. Our technicians recommend using the factory type timing tool for the replacement procedure.

A low speed stall when the throttle pedal is slightly pressed and released may mean the Engine Control Module (ECM) needs to be reflashed (updated).

A chirping or squeaking noise may be noted from the front of the vehicle when traversing bumps at low speeds. Our technicians tell us this type of noise is generally caused by the front strut mounts which will require replacement.

The engine may develop a crank no start condition due to a faulty ignition switch. The ignition switch will require replacement to correct this concern.

The Check Engine Light may illuminate with a stored code P2006. This is most often caused by a sticking intake manifold runner control (IMRC) valve. Our technicians tell us that depending on your vehicle the valve may require replacement and/or the powertrain control module (PCM) software will require upgrading.

A dirty, or contaminated mass airflow sensor (MAF) can cause the engine to run poorly. The Check Engine Light may or may not illuminate.  MAF sensor related fault codes P0102 and/or P0103 may be stored. In some cases, carefully cleaning the sensor element will fix the problem. If not, replacement of the sensor may be required.

If the engine is misfiring, it may be caused by a damaged wire(s) which connect the fuel injectors to the Powertrain Control Module (PCM). The damaged wire(s) can be repaired or the emission wire harness replaced. A misfire can result in a loss of engine performance and illumination of the Check Engine Light.
