2008 Chevrolet Tahoe Hybrid ProblemsReduced Power and Check Engine Light
The throttle position sensor (TPS) on the Chevrolet Tahoe Hybrid 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 on the gasoline engine, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS. Note, this does not affect the hybrid drive system.
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 may cause 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.
