Clutch position sensor
Hi all,
I am looking for a clutch position sensor. There will be one on any of various V70s and C70s with a manual gearbox. If yours works so much the better (the resistance changes out of acceptable range and throws an ETS error), but even if it doesn't work I am interested in the housing because I want to do some tinkering to see if I can come up with a reliable solution. It lives up behind the clutch and brake pedal cluster, and you can unplug it if you crouch down in the drivers footwell. Please drop me a PM with what you have and include postage to me in UK. Thanks Steve

How is yours not working Steve?
What are your symptoms?

Hi Cheshired5
ETS light is on. If I start the car with the pedal halfway down, there is no ETS light until I release the pedal. VIDA reports ECM-9300 Clutch pedal position sensor. Faulty signal. If I remove the sensor the resistances compressed are 300 ohms and extended 4.4 kOhms Supply voltage is about 5v, which I believe is as expected. I believe the acceptable ranges are something like Unpressed pedal=1400-2400 ohms Fully Depressed pedal= 200-800 ohms Unfortunately this is a new sensor which I only put in the car a couple of weeks ago (the old one was physically broken). Worked fine initially, now failed. A new sensor (part number is 9472979) is about 60 pounds. But I really don't want to put a new one in and have it fail again. There are quite a few posts out there about this problem. I intend to put a 7 kohm resistor in parallel to reduce the effective resistance of the sensor. I believe that this faulty sensor is also having other side effects on the engine (hesitation and lack of power). Other later models experience similar but slightly different side effects (inhibited ability to crank). Have you dealt with this situation before? Steve

Yes quite a few times as CPS faults are common on P2s.
Post #23 and #24 in this thread give you a couple of fix options.

Hi
Yes, thanks. I hadn't read that particular thread, but I had read others that were similar. I looked for leaked clutch fluid inside the sensor but that was inconclusive. Anyway I cleaned the tracks a few times with brake cleaner, meths and finally warm water but none of those changed any resistance values. I have opened the casing up, and soldered two thin wires to the terminals inside, enlarged a small hole in the casing, then brought the wires out through that. Currently waiting for some resistors and potentiometers to arrive in the post so I can connect them to the wires and set the resistance to what I want, then refit to the car. If it conclusively fixes the ETS light and hopefully improves performance, I will report back. I wanted some used sensors to play with in case things go terribly wrong! Steve

Are the resistance values going down and up uniformly in line with how much you contract and extend the rod?
