This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the sensor that tells the car how much you are pressing the gas pedal. Sometimes it works, sometimes it doesn't.
The P2134 code is triggered when the Engine Control Module (ECM) detects an intermittent signal from the Throttle/Pedal Position Sensor/Switch F circuit.
The throttle/pedal position sensor/switch F is responsible for sending the ECM information about the position of the throttle or pedal. If the signal from this sensor is not consistent, the ECM may not be able to accurately control the throttle, leading to performance issues.
• Check Engine Light is on
• Poor acceleration
• Engine may go into 'limp' mode
• Faulty throttle/pedal position sensor
• Wiring issues such as loose connections or damaged wires
• Faulty ECM
ECM: Engine Control Module, the computer that controls engine functions.
Throttle Body: A component of the air intake system that controls the amount of air entering the engine.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connections to the sensor
• Test the throttle/pedal position sensor for proper operation
• Repair or replace damaged wiring or connectors
• Replace the throttle/pedal position sensor
• Reprogram or replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance checks
• Ensure wiring is secure and free from damage
• Use quality replacement parts
Sensor Issue
• Avoid driving at high speeds until the issue is resolved
• Consult a professional mechanic for diagnosis and repair
Check with your vehicle manufacturer for specific warranty coverage on sensors and ECM components.
P2134 is a relatively common code associated with throttle position sensor issues, often seen in vehicles with electronic throttle control systems.
Moderate – Should be addressed soon to avoid potential drivability issues.
Driving with a malfunctioning throttle position sensor can lead to unexpected acceleration or deceleration, posing a safety risk.
• Engine running
• Vehicle in park or neutral
The throttle/pedal position sensor is typically located on the throttle body or near the accelerator pedal.
Q: Can I drive with a P2134 code?
A: It's not recommended to drive with this code as it can affect vehicle performance and safety.
Q: How do I reset the P2134 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, the code may return.
