This summary uses the existing diagnostic information shown in full below.
Your car has a special sensor that helps control how much gas goes to the engine. This code means that sensor isn't working right because it's not getting enough power.
The P212C code indicates that the voltage in the circuit for the throttle position sensor/switch G is lower than expected. This sensor helps the car's computer know the position of the throttle.
The throttle position sensor (TPS) G is responsible for sending data to the engine control module (ECM) about the position of the throttle. A 'circuit low' condition suggests that the voltage in the sensor's circuit is below the threshold set by the manufacturer, which may affect engine performance and throttle response.
• Check Engine Light is on
• Reduced engine performance
• Poor throttle response
• Faulty throttle position sensor
• Wiring issues such as short circuits or open circuits
• Poor electrical connections in the sensor circuit
Throttle: A device controlling the flow of fuel or power to an engine.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use an OBD-II scanner to confirm the code
• Inspect the throttle position sensor and its wiring for damage
• Check for loose or corroded connections in the sensor circuit
• Replace the faulty throttle position sensor
• Repair or replace damaged wiring
• Clean and secure electrical connections
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain the throttle position sensor
• Ensure electrical connections are clean and secure
• Address any wiring issues promptly
Sensor Issue
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional if unsure
• Avoid driving aggressively until the issue is resolved
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
The P212C code has been associated with throttle position sensor issues in various vehicle models over the years, often related to wiring problems or sensor failures.
Moderate – While the vehicle may still be drivable, addressing the issue promptly can prevent further engine performance problems.
Driving with a faulty throttle position sensor can lead to reduced engine performance and may not comply with emissions regulations.
• Engine running
• Throttle engaged
The throttle position sensor is typically located on the throttle body, which is connected to the engine's intake manifold.
Q: Can I drive with a P212C code?
A: While you might be able to drive, it's not recommended as it can affect engine performance and could lead to further issues.
Q: How do I reset the P212C code?
A: After addressing the issue, you can use an OBD-II scanner to clear the code. However, if the problem persists, the code will reappear.
