This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading the position of the clutch. It's like when you try to play a video game, but the controller isn't working right.
The P087C code indicates that the vehicle's powertrain control module (PCM) has detected a low voltage signal from the clutch position sensor B circuit.
The clutch position sensor B is responsible for providing the PCM with information about the clutch's position. A 'circuit low' condition means that the voltage signal from the sensor is below the expected range, which can affect the vehicle's ability to shift gears properly.
• Check Engine Light is on
• Difficulty in shifting gears
• Poor vehicle performance
• Faulty clutch position sensor B
• Wiring issues such as short circuits or open circuits in the sensor circuit
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the clutch position sensor B and its wiring for damage.
• Test the sensor's voltage and resistance to ensure it is operating correctly.
• Replace the faulty clutch position sensor B.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford Focus
• Chevrolet Cruze
• Honda Civic
• Regularly inspect and maintain the clutch system.
• Ensure all electrical connections are secure.
• Avoid aggressive driving that may wear out the clutch prematurely.
Sensor Issue
• Have the vehicle inspected by a professional mechanic.
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
Check with your vehicle manufacturer for warranty coverage on drivetrain components.
This code has been associated with vehicles that have electronic clutch control systems, becoming more common as these systems are adopted.
Moderate – It is advisable to address the issue soon to avoid potential transmission damage.
Ignoring this code may lead to unsafe driving conditions due to transmission issues.
• Vehicle should be in a safe, stationary position.
• Ensure the engine is off and the battery is disconnected before testing electrical components.
The clutch position sensor is typically located near the clutch pedal or on the transmission housing.
Q: Can I drive with a P087C code?
A: It's not recommended as it may lead to transmission issues and unsafe driving conditions.
Q: How can I reset the P087C code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is fixed first.
