This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble understanding how much you're pressing the gas pedal. It's like when you can't tell how hard you're pressing a button on a video game controller.
The P0226 code indicates that the engine control module (ECM) has detected a problem with the range or performance of the throttle/pedal position sensor/switch C circuit.
The throttle/pedal position sensor/switch C is responsible for sending a signal to the ECM indicating the position of the throttle or pedal. If the ECM detects a signal that is out of the expected range or inconsistent with other sensor inputs, it triggers the P0226 code.
• Check Engine Light is on
• Poor acceleration
• Vehicle may go into 'limp' mode
• Faulty throttle/pedal position sensor
• Wiring issues or poor connections in the sensor circuit
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle/pedal position sensor and wiring for damage.
• Test the sensor with a multimeter to check for proper operation.
• Replace the throttle/pedal position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and clean throttle body and sensors.
• Ensure all electrical connections are secure and free of corrosion.
• Follow scheduled maintenance for your vehicle.
Sensor Issue
• Avoid driving at high speeds until the issue is resolved.
• Consult with a professional mechanic for accurate diagnosis.
• Do not ignore the Check Engine Light.
Check with your vehicle manufacturer; some sensor issues may be covered under warranty.
The P0226 code has been commonly reported in vehicles with electronic throttle control systems, especially in models from the early 2000s.
Moderate – It should be addressed soon to avoid potential drivability issues.
Driving with a malfunctioning throttle sensor can lead to unexpected vehicle behavior, which may be unsafe.
• Engine running
• Vehicle stationary
The throttle/pedal position sensor is typically located on the throttle body or near the accelerator pedal.
Q: Can I drive my car with a P0226 code?
A: It's not recommended as it can lead to poor performance and potential safety issues.
Q: How do I clear a P0226 code?
A: The code can be cleared with an OBD-II scanner, but the underlying issue should be fixed first.
