P2134 Fault Code

Throttle/Pedal Position Sensor/Switch F Circuit Intermittent

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

• The P2134 fault code indicates an issue with the Throttle/Pedal Position Sensor/Switch F circuit.
• This code typically appears when the Engine Control Module (ECM) detects a fault in the throttle position sensor or related circuits, which may lead to unintended acceleration or reduced power.
• The throttle position sensor (TPS) is crucial for regulating the engine's air-fuel mixture, affecting overall vehicle performance and emissions.

What are the symptoms of the P2134 code?

• Symptoms that may accompany the P2134 code include:
  • Check Engine Light illuminated on the dashboard.
  • Unresponsive or erratic throttle response.
  • Reduced engine power or limp mode activated for safety.
  • Increased fuel consumption due to improper air-fuel mixture.
  • Unexpected stalling or hesitation during acceleration.

What causes the P2134 code?

• Common causes for the P2134 code include:
  • Faulty throttle position sensor.
  • Poor electrical connections or wiring issues in the throttle position sensor circuit.
  • Issues with the accelerator pedal position sensor.
  • A malfunctioning Engine Control Module (ECM).
  • Contaminants or damage affecting sensor performance.

How to fix P2134?

• To resolve the P2134 fault code, the following steps may be necessary:
  • Inspect and repair wiring and connectors related to the throttle position sensor.
  • Test and replace the throttle position sensor if it's found to be faulty.
  • Check the accelerator pedal position sensor and replace if necessary.
  • Clear the fault codes with a professional diagnostic tool and perform a road test to ensure proper operation.
  • If all components are functioning properly but the code persists, consider reprogramming or replacing the ECM.
