P2133 Fault Code

Throttle/Pedal Position Sensor/Switch F Circuit High

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

The P2133 fault code indicates that there is a high voltage signal detected from the throttle/pedal position sensor or switch F circuit. This sensor plays a crucial role in monitoring the position of the accelerator pedal, which helps to regulate the engine's throttle response. When the voltage is higher than expected, it can lead to performance issues and affect the vehicle's drivability.

• The throttle position sensor works with the engine control unit (ECU) to adjust the air-fuel mixture.
• If the sensor reports incorrect readings, it can trigger the check engine light and lead to various driving problems.

What are the symptoms of the P2133 code?

Symptoms associated with the P2133 fault code may include:

• Check engine light is illuminated on the dashboard.
• Poor acceleration or a noticeable lack of power.
• Erratic or unresponsive throttle behavior while driving.
• Engine stumbling or stalling.
• An increase in fuel consumption due to improper air-fuel mixture due to sensor malfunction.

What causes the P2133 code?

Common causes of the P2133 code include:

• A malfunctioning throttle position sensor leading to incorrect readings.
• Faulty wiring or connections in the throttle position sensor circuit.
• A faulty accelerator pedal position sensor that affects the signal being sent to the ECU.
• Electrical shorts or open circuits in the sensor's wiring.
• Potential issues with the engine control module (ECM) that misinterpret the sensor's data.

How to fix P2133?

To address the P2133 fault code, the following steps can be taken:

• Inspect and replace the throttle position sensor if it is found to be defective.
• Check the wiring and connectors in the throttle position sensor circuit for any damage, corrosion, or loose connections, and repair as necessary.
• Perform a calibration of the throttle position sensor if applicable.
• Clear the diagnostic trouble code from the ECU and test drive the vehicle to ensure the issue is resolved.
• If the problem persists, further investigation into the ECU and related components may be required.
