2009 Chevrolet Express 2500 Problems
RepairPal has identified the most common problems with the 2009 Chevrolet Express 2500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The fuel pump may fail causing the engine to stall and not restart.
The throttle position sensor (TPS) on the Chevrolet Express 2500 is notorious for failure which causes:
- Check engine light
- Reduced Power message
- OBD trouble code P2135
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.
To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.
A loose or worn gas cap could be cause the Check Engine Light to illuminate.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
The tail light wiring harness in the cargo area is not protected very well. As a result it may become damaged due to normal wear a tear. This damage can causing some or all of the rear lights to stop working.
