Check engine light came on and dealer pulled this code. He said it was the P/N Inhibit switch. I removed the switch, disassembled, cleaned the contacts and put it back together. I tested all the pins on the plug for continunity as per a Mitchell page I was able to aquire. Every thing checked ok. I was told to check pin 39 on the ATCU and it should have battery voltage with the Overdrive swithch "On" to ground. I only get 9.13 volts here. Can anyone please tell me where to try from here. I don't want to start replacing parts if they don't need it. Thanks.

 

I drove the car 200 plus miles. No check engine light yet. Still don't understand about the voltage to ground at pin 39 on the ATCU but everything seems ok. If anyone has any information on that please let me know.
