This code means that the car's computer is having trouble understanding how far the clutch pedal is being pressed. It's like when you can't tell how far you've pushed a button on a video game controller.
The P1855 code indicates a problem with the clutch control travel sensor, which monitors the position of the clutch pedal. The sensor's signal is out of the expected range or performance parameters.
The clutch control travel sensor is responsible for sending data about the clutch pedal position to the vehicle's powertrain control module (PCM). When the PCM detects that the sensor's signal is not within the expected range, it triggers the P1855 code. This could be due to a faulty sensor, wiring issues, or other related problems.
• Check Engine Light is on
• Difficulty shifting gears
• Clutch pedal feels unusual
• Faulty clutch control travel sensor
• Damaged or corroded wiring or connectors
• Faulty PCM
PCM: Powertrain Control Module, the vehicle's computer that manages engine and transmission functions.
OBD-II: On-Board Diagnostics, a standardized system for self-diagnostics and reporting.
• Use an OBD-II scanner to confirm the code.
• Inspect the clutch control travel sensor and its wiring for damage.
• Test the sensor's signal with a multimeter.
• Replace the clutch control travel sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford Focus
• Volkswagen Jetta
• Honda Civic
• Regularly inspect clutch system components.
• Ensure wiring and connectors are free from corrosion.
• Perform routine vehicle maintenance.
Sensor Issue
• Have the vehicle inspected by a professional mechanic.
• Avoid driving the vehicle if gear shifting becomes difficult.
Check with your vehicle manufacturer for warranty coverage on sensor-related issues.
This code has been reported in vehicles with manual transmissions, often related to sensor wear over time.
Moderate – It should be addressed soon to avoid potential driving issues.
Driving with a faulty clutch sensor can lead to unsafe driving conditions. It is advisable to get it checked promptly.
• Engine running
• Clutch pedal operation
The clutch control travel sensor is typically located near the clutch pedal assembly.
Q: Can I drive with the P1855 code?
A: It's not recommended to drive with this code active, as it can affect the vehicle's ability to shift gears properly.
Q: How do I reset the P1855 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
