Justy ECVT Cable Adjustments

Before attempting to repair ECVT driveability complaints make sure the throttle cable from the gas pedal to the carburetor or MPI throttle body bell crank is properly adjusted. With the gas pedal at rest, carefully measure from the horizontal center of the pedal pad to the floor or carpet, the measurement must be between 3-7 mm or (0.12-0.28 in.) for the micro switches to disengage according to pedal depressions. Remember to remove the driver's floor mat before measuring. Then, adjust the ECVT cable from the carburetor or MPI injector (depending on fuel system) bell crank to the valve body. The specification is 0.5 mm (0.020 in.) of thrust freeplay.

If carbureted, the vehicle must be fully warmed-up (no choke interference). Have another Tech hold the gas pedal to the floor. Using a felt marker, put a mark on the cable just after the black rubber cable protector. Check the measurement against the spec.


Some helpful hints:

^ A cable which is TOO LOOSE may be disconnected or not positioned properly in the bell crank slot in the valve body. Up ratio of pulleys will be too fast.
^ A cable which is TOO TIGHT may cause the ECVT to have problems with the pulleys staying in low ratio longer.

NOTE: Always refer to the applicable Service Manual. Don't forget the ECVT Supplement for 1990 MSA5T9024D (ECU Diagnostics). Also use Bulletin 16-38-90, Dated 4-2-90 titled "Intermittent ECVT Check Lamp Illumination, Trouble Code 21" can be found in Service Bulletin Manual 12.
