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
