Throttle/Pedal Position Sensor B Maximum Stop Performance
This code means that the car's computer thinks the gas pedal or throttle isn't stopping where it's supposed to. Imagine if your video game controller's joystick got stuck and didn't return to the center position.
The engine control module (ECM) has detected that the throttle/pedal position sensor B is not reaching its expected maximum stop position.
The P2164 code is triggered when the ECM detects that the throttle/pedal position sensor B is not reaching its maximum stop performance. This could be due to a sensor malfunction, wiring issue, or a mechanical problem with the throttle body.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the throttle/pedal position sensor B.
• Check for mechanical obstructions in the throttle body.
• Replace the throttle/pedal position sensor B if faulty.
• Repair or replace damaged wiring or connectors.
• Clean or repair the throttle body if there is a mechanical issue.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and clean the throttle body.
• Ensure all electrical connections are secure.
• Perform routine maintenance checks.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Avoid driving aggressively if the vehicle is in limp mode.
Check with your vehicle manufacturer for warranty coverage on sensors.
This code has been associated with throttle body issues in vehicles with electronic throttle control systems.
Moderate – While the vehicle may still be drivable, performance issues can arise, and further damage could occur if not addressed.
Driving with a malfunctioning throttle sensor can lead to reduced vehicle performance and safety hazards.
• Engine at operating temperature
• Vehicle stationary with ignition on
The throttle/pedal position sensor B is typically located on the throttle body or the accelerator pedal assembly.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to poor vehicle performance and potential safety risks.
Q: Can I drive my car with this code?
A: While it may be possible to drive, it's not recommended due to potential performance issues and safety concerns.
