I'm posting for my Dad who has a 96 E300D

At the end of last winter the car started stalling intermittently and got worse. The CCPS was replaced and fixed the problem.

At the end of the summer the same thing started happening. The CCPS was found to be bad and replaced again.

For a few weeks the car ran and started acting the same way. The CCPS sensor was bad again and with a replacement the car is running again.

Is there anything wiring wise that would cause this sensor to short out.? There are no signs of physical marring when they are taken out. If there is a potential shorting of the harness does anyone know where the sensor is located and where it taps into the computer and ground (I assume it's a send and ground wiring harness) so new wires can be ran between the two points?

Thanks!
