This summary uses the existing diagnostic information shown in full below.
This code means that a part of the car that tells the engine how much gas you're giving it is not working right. It's like the car's brain isn't getting the right message about how much you're pressing the gas pedal.
The throttle position sensor (TPS) on Bank 2 is sending a signal that is higher than expected, indicating a possible issue with the sensor or its circuit.
The P168C code is triggered when the Powertrain Control Module (PCM) detects a voltage level in the throttle position sensor circuit for Bank 2 that is higher than the specified range. This could be due to a faulty sensor, wiring issues, or a problem with the PCM itself.
• Check Engine Light is on
• Poor engine performance
• Hesitation or stalling during acceleration
• Faulty throttle position sensor
• Wiring issues such as shorts or open circuits
• Faulty PCM
Throttle Position Sensor (TPS): A sensor that monitors the position of the throttle in an internal combustion engine.
PCM: Powertrain Control Module, the brain of the vehicle that controls the engine and transmission.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the throttle position sensor using a multimeter.
• Replace the throttle position sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Chevrolet Silverado
• Ford F-150
• Dodge Ram
• Regular maintenance checks
• Ensure wiring harnesses are secure
• Keep sensors clean
Sensor Issue
• Avoid driving the vehicle until the issue is fixed to prevent further damage.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle's manufacturer for warranty coverage on emission-related components.
This code has been known to appear in vehicles with high mileage or those that have experienced previous electrical issues.
Moderate – It is recommended to address this issue promptly to avoid potential engine performance problems.
Driving with a malfunctioning throttle position sensor can lead to unsafe driving conditions. Ensure repairs are made to maintain vehicle safety.
• Engine running
• Vehicle at operating temperature
The throttle position sensor is typically located on the throttle body of the engine.
Q: Can I drive my car with a P168C code?
A: It's not recommended to drive with this code active as it can lead to poor engine performance and unsafe driving conditions.
Q: How can I reset the P168C code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, the code should not return.
