This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks something is wrong with how the gas pedal and brake pedal are working together. It's like when you try to run and stop at the same time, which doesn't make sense.
The car's computer monitors the signals from the accelerator and brake pedals to ensure they make sense together. If the signals are not logical, it triggers this code.
P1514 is triggered when the Engine Control Module (ECM) detects an implausible correlation between the accelerator pedal position and the brake pedal position. This could indicate a problem with the sensors or wiring that report these positions to the ECM.
• Check Engine Light is on
• Reduced engine performance
• Unresponsive accelerator pedal
• Faulty accelerator pedal position sensor
• Faulty brake pedal position sensor
• Wiring issues between the sensors and the ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the accelerator and brake pedal position sensors for proper operation.
• Replace faulty sensors.
• Repair or replace damaged wiring.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly inspect pedal sensors and wiring.
• Keep the vehicle's electrical system in good condition.
• Avoid harsh driving conditions that could damage sensors.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you notice performance issues.
Check with your vehicle manufacturer as sensors may be covered under powertrain warranty.
This code has been reported in vehicles with electronic throttle control systems, especially in models with high mileage.
Moderate – It should be addressed soon to prevent potential drivability issues.
Driving with this code can lead to reduced performance and safety risks. Address it promptly.
• Vehicle at operating temperature
• Engine running
The accelerator pedal position sensor is located on the accelerator pedal assembly, and the brake pedal position sensor is located near the brake pedal.
Q: Can I drive with a P1514 code?
A: It's possible to drive short distances, but it's not recommended as it may lead to performance issues.
Q: How do I reset the P1514 code?
A: After repairs, use an OBD-II scanner to clear the code, then test drive to ensure the issue is resolved.
