Shining Some Light on the Problem

A 1996 Nissan 300ZX came into the shop last summer. Remember, I said it was summer, which affects this story later.

The customer said the check engine light was on and that at times the transmission would not shift into fourth gear. I scanned the computer and found a P0705 inhibitor-switch code. I cleared the code and went for a test drive with the scan tool connected. Inhibitor-switch data was correct, and the code did not reset.
