This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting confusing signals from the sensors that tell it how much you're pressing the gas pedal. It's like when you tell your friend to go faster, but they hear you say go slower at the same time.
The car's computer is detecting a mismatch in the voltage signals from the throttle or pedal position sensors E and F.
The P2140 code is triggered when the Engine Control Module (ECM) detects a difference in the voltage signals from the throttle or pedal position sensors E and F that is outside of the expected range. These sensors are responsible for sending the position of the throttle or pedal to the ECM, which uses this information to control the engine's power output.
• Check Engine Light is on
• Reduced engine performance
• Vehicle may go into 'limp' mode
• Faulty throttle position sensor
• Wiring issues such as shorts or open circuits
• Faulty pedal position sensor
Throttle Position Sensor: A sensor that monitors the position of the throttle in an internal combustion engine.
Pedal Position Sensor: A sensor that detects the position of the accelerator pedal.
• Scan for codes and verify P2140 is present
• Inspect wiring and connectors for damage
• Test the throttle and pedal position sensors for proper operation
• Replace faulty throttle position sensor
• Repair or replace damaged wiring/connectors
• Replace faulty pedal position sensor
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regular maintenance checks
• Inspect wiring for wear and tear
• Ensure sensors are clean and functioning
Sensor Issue
• Avoid driving the vehicle until the issue is resolved
• Consult a professional mechanic for diagnosis and repair
Check with your vehicle manufacturer for warranty coverage on throttle and pedal position sensors.
P2140 has been a common code in vehicles with electronic throttle control systems, particularly as vehicles age and wiring or sensors degrade.
Moderate – This issue can affect drivability and should be addressed soon to avoid further complications.
Driving with a malfunctioning throttle or pedal position sensor can lead to unexpected vehicle behavior, posing a safety risk.
• Engine running
• Vehicle in park or neutral
The throttle position sensor is typically located on the throttle body, while the pedal position sensor is located near the accelerator pedal.
Q: Can I drive with a P2140 code?
A: It's not recommended as it can lead to reduced engine performance and potential safety issues.
Q: How do I reset the P2140 code?
A: After repairs, the code can be cleared using an OBD-II scanner. However, if the issue persists, the code will return.
