Subject
SPEEDOMETER INOPERATIVE AND/OR MIL ILLUMINATION W/CODE P0500
APPLICABLE MODEL(S)/VINS
All 1994 - 1998 626 FS (A/T) with VINs lower than 1YV GF 22C7W5704801 (built before 11/7/97).
DESCRIPTION
The speedometer may become inoperative and/or the MIL may illuminate with the Diagnostic Trouble Code (DTC) P0500 stored in memory. This may also be accompanied by fail-safe shift mode (locked in third gear), and a lack of power.
This subject may be caused by insufficient clearance between the speedometer drive gear on the differential and the driven gear of the speedometer gear set. This insufficient clearance causes excessive force to be applied to the speedometer driven gear shaft, resulting in contact between the shaft and magnets or premature wear of the speedometer gear set. A modified speedometer gear set is available which allows the correct clearance between the gears.
Customers complaining of this subject should have their vehicle repaired using the following procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Remove the speedometer drive gear and inspect the gear teeth for any missing, burred, or severely damaged teeth.
If the teeth appear normal, install the revised speedometer gear set. See PART(S) INFORMATION.
If the teeth are severely damaged, the drive gear on the differential will also be damaged, requiring transmission replacement. Contact the Technical Assistance Hotline for authorization if necessary.
3. Verify the repair.
