Clutch Pedal Position Switch
I know the clutch position switch is essentially 3 switches in one. Three circuits are being controlled: starter relay, speed control, and as a "sensor" to the PCM.
So what does the PCM circuit do? How does the PCM use this information?
My truck is automatic, but my friends 2003's cruise wasn't working. So I did the diagnostic mode and it flashed twice. He said he could start his vehicle without pushing in the clutch. I checked the clutch switch and it was loose on the rod. No springy resistance. So I took the jumper out of mine and the cruise worked. But I noticed the jumper only had 4 pins and only jumped the starter and speed control circuits. So this got me curious about the PCM circuit.
