Circuit Description

The Clutch Pedal Position Switch is a normally closed switch. The PCM applies a voltage (B+) to the Clutch Pedal Position Switch circuit. When the Clutch Pedal Position Switch is depressed (clutch pedal released) the circuit is open and the PCM senses a high voltage. When the Clutch Pedal Position Switch is released (clutch pedal depressed) the Clutch Pedal Position Switch contacts close, causing the applied voltage to go low.

The PCM determines if the Clutch Pedal Position Switch has failed by not sensing a clutch switch transition. The PCM monitors vehicle speed from 0 to a predetermined speed.

English translation= Take the bottom panels out of the car (Like you were adjusting the clutch). The clutch hits a solonoid attached to it towards the top (you cant miss it). This solonoid is threaded so of you had to adjust your clutch farther down you can turn the solenoid and it will come in contact with the clutch again when you are not pressing it down. I had the same problem.

No problems shifting at all when it was on. I think it will effct the way the car runs or at least idles but I have yet to clarify this.
