I can add some notes here for anyone that has been brought here for a search on the clutch linear sensor or codes C1A41-21, P0805-95, P164C-93
The linear clutch sensor has as pin 1 ground, pin 2 signal, pin 3 5V ref. They are numbered 1 - 4 from the bottom up of the clip. Normally, with the clutch out the signal voltage will be ~0.4V and depressed the voltage is ~2.4
I've had the pleasure of going through these C1A41-21, P0805-95, P164C-93 because in the original master there is a magnetic ring on the piston crown that tells the hall sensor how many volts to output which tells the ecu whats going on. They really engineered this thing to be impossibleto start in certain scenarios. So my cautionary tale is this;
When replacing the master, check the new one for that magnet because the car will not start, despite the reliability of the TOT and BOT switches, plus the neutral sensor, plus 1st gear sensor, apparently this is not enough to convince the ecu that it's ok to start.
At least this appears to be the problem. I've asked the manufacturer, for those interested in Australia it came from ClutchPro - MCFD059. Its not a fun job to do twice.
Cheers
