1997 Ford F150 6 cyl Two Wheel Drive Automatic 113000 miles
My son has a 97 F150 and the speedometer and odometer has stopped working. At first it was an intermittent problem and now the speedometer suddenly pegged at over 100MPH. This happened while going less than 20 MPH. The odometer has also stopped working. All of the other gauges on the instrument cluster work perfectly except for the speedometer and odometer. This is a mechaincal gauge cluster and not a digital one. Turning off the key does not reset the speedometer or odometer.
Thanks for your help.
SPEEDOMETER & ODOMETER INOPERATIVE 1. Verify Cruise Control Operation - Drive vehicle and check cruise control operation. If cruise control operates properly, go to next step. If cruise control does not operate, see appropriate CRUISE CONTROL SYSTEM article. Repair as necessary. 2. Check VSS PID - Using New Generation Star (NGS) scan tester, access GEM. Select VSS PID. Monitor VSS PID while driving vehicle. If VSS PID seems to indicate actual vehicle speed, go to next step. If VSS PID does not indicate actual vehicle speed, go to step 4). 3. Check Gray/Black Wire For Open - Turn ignition off. Disconnect NGS scan tester. Disconnect instrument cluster harness connector C237 and VSS harness connector. Measure resistance of Gray/Black wire between C237 pin No. 7 and VSS harness connector. If resistance is less than 5 ohms, repair/replace instrument cluster. If resistance is greater than 5 ohms, repair open Gray/Black wire. Check speedometer operation. 4. Check VSS - Turn ignition off. Disconnect NGS tester. Disconnect VSS harness connector. Measure resistance between VSS terminals. If resistance is 200-300 ohms, go to next step. If resistance is not 200-300 ohms, replace VSS. Check speedometer operation. 5. Check Pink/Orange Wire For Open - Measure resistance of Pink/Orange wire between VSS harness connector and ground. If resistance is less than 5 ohms, repair open Gray/Black wire. If resistance is greater than 5 ohms, repair open Pink/Orange wire. Check speedometer operation. Page 1 of 1 INSTRUMENT PANEL - ANALOG (EXCEPT F250 HD & F350) -1997 Ford Pickup F1. 6/20/2009

Your answer does not help. The truck does not have cruise control. Please refund my money.

I sent you a file, did you read it? Also if it has ne cruise, follow the part where it says if cruise does not work. It's all there. I mistakenly assumed you wanted to check it out b4 you started to throw parts into it, I guess not. So go ahead and replace the IP. And the VSS, that ought to get it working.
