9000 L4-2290cc 2.3L DOHC Turbo EFI (1992)
2.
Attach a digital multimeter to the plug attached to the transducer. Set the meter to the AC volts range.
3.
Drive the car and observe the meter. The voltage reading should increase as the speed increases. If not, proceed with checking the gears.
4.
If the transducer and gears are correct and operating properly, the cause of the fault lies elsewhere in the wiring, speed sensor, or speedometer.
To test out of the car:
1.
Remove the transducer from the gearbox, if fitted.
2.
Connect a multimeter to the 2-pole connector. Set the meter to the AC volts range.
3.
Spin the transducer input shaft by finger and watch the meter display. If the voltage changes, the transducer is functioning. If not, replace the
transducer.
4.
If the transducer and gears are correct and operating properly, the cause of the fault lies elsewhere in the wiring, speed sensor, or speedometer.
Speedometer Gears Inspection Procedure
(Gearbox in or out of car)
1.
Remove the electronic speed transducer from the guide sleeve, if fitted.
2.
Remove the roll pin or screw securing the guide sleeve into the transmission housing.
3.
Remove the guide sleeve, together with the plastic driven gear, from the housing.
Warranty Information:
For warranty claims, use Failure Coding 47320-02-W-01. Time allowance is Operation No. 47320 (0.3 hr).
4.
Determine which type of metal drive gear is fitted to the differential housing by inserting a finger into the hole for the guide sleeve. Try moving the
drive gear with your finger. If it is possible to feel the gear move up and down, about 1/4 inch, the early-style drive is fitted. If not, it is the
late-style press-fit gear.
5.
Inspect the plastic driven gear by counting the number of teeth. Gear 87 23 892 has 13 teeth and should be used with the early-style (loose) drive
gear. Gear 87 27 240 is slightly larger in diameter, having 15 teeth, and should be used with the late-style (tight) drive gear.
6.
If an incorrect driven gear is fitted, replace it with the proper type, using the gear out of the original transmission if possible. The driven gear can
be removed from the guide sleeve by pulling the two pieces apart. Insert the new gear into the guide sleeve and snap the two parts together.
7.
Ensure that the o-ring and seal on the guide sleeve are not damaged and refit the gear/guide sleeve into the gearbox housing, securing them into
place. Apply thread sealer to the screw, if used.
