P2168 Fault Code

Throttle/Pedal Position Sensor F Maximum Stop Performance

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2168 code indicates that the Throttle/Pedal Position Sensor F (TPMS F) has reached its maximum stop performance. This code can trigger the Check Engine Light (CEL) and usually points to issues with the sensor's calibration or its electrical connection.

• Throttle position sensors play a crucial role in determining the correct air-fuel mixture for optimal engine performance.
• When the sensor is out of range, it can lead to poor acceleration, stalling, or rough idling.
• It's essential to address this issue promptly to maintain the vehicle's efficiency and performance.

What are the symptoms of the P2168 code?

Common symptoms associated with the P2168 code may include:

• Engine warning light illuminated on the dashboard
• Decreased engine performance, including poor acceleration
• Stalling or hesitation during acceleration
• Unresponsive throttle input or 'limp' mode activation
• Rough idling or increased fuel consumption.

What causes the P2168 code?

Several factors can lead to a P2168 code, including:

• Faulty Throttle/Pedal Position Sensor F
• Wiring issues such as short circuits or open connections
• Corrosion or damage at connector terminals
• Software glitches in the Engine Control Unit (ECU)
• Accidental or intentional throttle stops set during maintenance or service.

How to fix P2168?

To resolve the P2168 code, consider the following steps:

• Inspect the Throttle/Pedal Position Sensor F for any physical damage or wear.
• Test the sensor voltage and resistance according to the manufacturer's specifications.
• Check for loose or corroded connections and repair as necessary.
• Clear the error code using a diagnostic scanner and conduct a test drive to confirm the issue is resolved.
• If the problem persists, consider reprogramming or replacing the ECU or the sensor if it's faulty.
