Check engine light came on and dealer pulled code 0705. 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.
