My Escort wagon runs fine, but the speedometer and odometer never move. Speedo stays at zero. No fluctuation. Odo never changes. The rest of the instrument cluster works fine.
OBD II code P0500 (details below).
This car does not have cruise control, so it's not related to that.
Has automatic transmission. Drives fine. I've heard a bad VSS would cause the engine to hesitate. So I'm doubting the VSS itself needs replacement. I've also read the VSS can be very difficult to extract.
I've looked directly at the VSS (removed the battery and air box), and the wires to it look fine and intact. Not even brittle. I gently wiggled the wires--they're solid.
I removed and checked the connectors at the battery's negative terminal. The plastic connectors look fine; not brittle; still have a little bit of that clear gel that I assume Ford puts on them to keep the metal clean.
But I suspect a wiring problem.
I'm skilled with a volt-ohmmeter, DVM and ammeter. Can I probe for certain signals on certain wires to troubleshoot this?
Ford circuit diagrams, schematics, and WIRES' LOCATIONS would be great to have!
Autozone provided this OBD II code: P0500. "Vehicle speed sensor circuit condition."
"The ECM has detected a fault in the vehicle speed sensor circuit."
"1. - Poor electrical connection or short circuit condition."
"2. - Failed vehicle speed sensor."
"3. - Drive gear mechanical fault."
What do you recommend?
have the same problem?
