It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The throttle position sensor (TPS) on the Chevrolet Silverado 2500 HD 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.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
The inside door handles are prone to breaking.
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.
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 keyless entry system may stop working. Our technicians tell us the key fobs and keyless entry receiver may need to be replaced to correct this fault.
