This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has found a problem with the sensor that tells it how much you are pressing the gas pedal on one side of the engine.
The P1227 code is triggered when the Engine Control Module (ECM) detects a problem with the range or performance of the throttle or pedal position sensor on bank 2.
The throttle/pedal position sensor/switch 'B' is responsible for sending the position of the throttle or pedal to the ECM. Bank 2 refers to the side of the engine that does not contain cylinder 1. A range/performance issue indicates that the sensor is not operating within the expected parameters, which could be due to a faulty sensor, wiring issues, or a problem with the ECM.
• Check Engine Light is on
• Poor engine performance
• Hesitation or stalling when accelerating
• Faulty throttle/pedal position sensor
• Wiring issues or poor connections
• Faulty ECM
ECM: Engine Control Module, the computer that controls engine functions.
Throttle Body: The component that controls the amount of air entering the engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle/pedal position sensor and its wiring for damage.
• Test the sensor for proper operation using a multimeter.
• Replace the faulty throttle/pedal position sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain the throttle system.
• Ensure proper electrical connections.
• Use quality replacement parts.
Sensor Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check if the vehicle's warranty covers sensor and ECM repairs.
This code has been associated with throttle position sensor issues in various models, especially in vehicles with electronic throttle control systems.
Moderate – It is recommended to address this issue soon to avoid potential drivability problems.
Driving with a faulty throttle position sensor can lead to unsafe driving conditions. Address the issue promptly.
• Vehicle at operating temperature
• Engine running
The throttle/pedal position sensor is typically located on the throttle body or near the accelerator pedal.
Q: Can I drive with a P1227 code?
A: It's not recommended to drive with this code as it can lead to poor engine performance and unsafe driving conditions.
Q: How do I reset the P1227 code?
A: After repairs, you can use an OBD-II scanner to clear the code. However, if the issue is not fixed, the code will return.
