dh5: Check TP Signal for Short to Power
| Steps | _Key Off, wait 10 seconds
_TP sensor disconnected _DVOM on 200,000 ohm scale _Disconnect processor 60 pin connector. Inspect for damaged pins, corrosion, loose wires, etc. Service as necessary. _Install breakout box, leave processor disconnected _Measure resistance between Test Pin 47 and Test Pins 26 and 57 at the breakout box. |
| Result | Are both resistances greater than 10,000 ohms? |
| Direction | YES
Service short circuit. Remove breakout box. Reconnect processor and TP sensor. Rerun Quick Test NO Remove breakout box. Replace processor. Reconnect TP sensor. Rerun Quick Test. |
