P2133 Code - Throttle/Pedal Position Sensor/Switch 'F' Circuit High

Quick Answer

The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P2133 indicates Throttle/Pedal Position Sensor/Switch 'F' Circuit High.
Common causes: Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2133 Description

The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. There are 2 pedal position signals in the sensor. Both signals, APP and APP2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The 2 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins) between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software converts these degrees to counts, which is the input to the torque based strategy.

Frequently Asked Questions about P2133 Code

1. What are the common symptoms of OBDII code P2133?

- Common symptoms include loss of power, engine stalling, hesitation during acceleration, and the vehicle going into "limp mode."

2. What are the possible causes of OBDII code P2133?

- Possible causes include a faulty throttle position sensor, damaged wiring or connectors in the throttle pedal circuit, or a problem with the electronic throttle control system.

3. How can I diagnose the cause of OBDII code P2133?

- Diagnosing the issue typically involves checking the throttle position sensor readings using a scan tool, inspecting the wiring and connectors for damage, and performing a throttle body relearn procedure.

4. Can driving with OBDII code P2133 cause further damage to the vehicle?

- Continuing to drive with this code can potentially lead to more serious issues, such as damage to the catalytic converter or the throttle control system.

5. Is it safe to continue driving if I experience symptoms related to OBDII code P2133?

- It is not recommended to drive the vehicle if you experience symptoms like loss of power or engine stalling, as it can be unsafe and may cause further damage.

6. How can I repair OBDII code P2133?

- Repairing this code may involve replacing the throttle position sensor, repairing or replacing damaged wiring or connectors, or recalibrating the throttle body.

7. Can a DIY enthusiast fix OBDII code P2133, or should I take it to a professional mechanic?

- While some DIY enthusiasts may be able to diagnose and repair this code, it is recommended to seek the expertise of a professional mechanic due to the complexity of the throttle control system.

8. How much does it typically cost to repair OBDII code P2133 at a repair shop?

- The cost of repairing this code can vary depending on the underlying issue, but it may range from $200 to $500 or more, including parts and labor.

9. Can resetting the OBDII code P2133 with a scan tool temporarily fix the issue?

- Resetting the code may temporarily clear the warning light, but if the underlying problem is not fixed, the code is likely to return, and the symptoms will persist.

10. How often does OBDII code P2133 occur in vehicles, and is it a common issue?

- OBDII code P2133 related to the throttle/pedal position sensor circuit high is a relatively common issue in vehicles equipped with electronic throttle control systems.
