Chevrolet Colorado Problems

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

The heater - AC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block.

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Replacement of the cylinder head may be required to correct this concern.

The CD player in the radio may fail. Our technicians tell us that the radio will need to be removed and sent out to a radio repair shop to correct this condition.

The throttle position sensor (TPS) on the Chevrolet Colorado LT 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 spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.
