good day everyone, yesterday my psm light went on and after awhile my check engine went on, I then went and had it check and they told me that its throttle/pedal position sensor switch d circuit low input. I would like to know if the faulty sensor is the cause for my psm light turning on and how complicated is it to replace this sensor myself.

Please advice me in what to do...Thank you Very Much.....

Good Morning.

PSM failures are very strange and most of the time in some way electric issues. 

First check voltage of your battery please

In addition i can tell you. On my very first cayenne i have it. Still until now. The porsche shop changed almost everything. Throttle body. MAF, a lot of sensors. 

Guess what, nothing solved the problem
