| Complaint: | Engine jerking may occur while driving and while rough idling engine may stall. Engine - poor startability. |
|---|---|
| Cause: | Vibrations at connector of coolant temperature sensor cause contact problems. |
| Production: |
Remedy:
In case of customer complaint replace the wiring harness of coolant temperature sensor and replace mating connector on the wiring harness.
Working Procedure:
Note:
On account of new gold contacts on the coolant temperature sensor, it is necessary to use gold plated connector contacts on the mating connector.
1. Remove upper engine compartment cover.
2. Remove wiring harness connector of coolant temperature sensor (under thermostat housing).
3. Cut wiring harness of coolant temperature sensor with diagonal cutting pliers on the wiring harness connector (displaced intersections) (picture I).
4. Measure and cut the new wiring harness on a length of 170 mm - 180 mm with diagonal cutting pliers.
5. Allocate cable, mark and plug it on the wiring harness connector. (picture II).
Note:
At vehicles with dust cover on the wiring harness connector coolant temperature sensor, reuse it for new wiring harness connector.
6. Strip cable ends with crimping tool MKM-923-31.
7. Put shrink sleeve over both cables and crimp the marked cable ends with crimping tool MKM-923-31 (picture III).
8. Put shrink sleeves over connections and heat it up with hot- air blower (picture IV).
9. Insulate complete wiring harness (picture V).
10. Attach insulated wiring harness in a bow with cable strap on the transmission wiring harness (picture VI).
11. Replace coolant temperature sensor
