Code P0122 2016 Chevrolet Silverado Description
The P0122 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the Throttle Position Sensor (TPS) 1 circuit registering low voltage. The TPS is a crucial component of the vehicle's electronic control system, as it constantly communicates with the engine control unit (ECU) to determine the appropriate throttle opening for optimal engine performance. When the TPS 1 circuit reports low voltage, it means that the signal being sent to the ECU is below the expected range, leading to potential issues with engine performance, fuel efficiency, and overall drivability.
Common Causes of P0122 2016 Chevrolet Silverado
- Faulty Throttle Position Sensor (TPS)
- Corroded or damaged TPS wiring harness
- Loose or poor electrical connections
- Issues with the ECU or related components
- Environmental factors such as moisture or debris affecting TPS operation
Symptoms of P0122 2016 Chevrolet Silverado
- Hesitation or lack of response when accelerating
- Rough idling or fluctuating engine speed
- Poor fuel efficiency
- Check engine light illuminated on the dashboard
- Reduced engine power or stalling
How to Fix P0122 2016 Chevrolet Silverado
- Diagnose the issue using a scan tool to confirm the P0122 code and identify the specific TPS 1 circuit fault.
- Inspect the TPS and wiring harness for any visible damage, corrosion, or loose connections. Replace or repair as needed.
- Test the TPS output voltage using a multimeter to ensure it falls within the manufacturer's specified range.
- Clear the DTC and reset the ECU by disconnecting the battery for a few minutes to see if the code returns.
- If the issue persists, consider replacing the TPS with a new genuine or OEM part to restore proper functionality.
Cost to Fix P0122 2016 Chevrolet Silverado
