Complaint: |
While driving engine jerking may occur and
in case of irregular idle speed, the engine may stall. The engine
shows bad starting characteristics. |
Cause: |
Relative movement in the area of the coolant
temperature-sensor resulting in damaged contact pins. |
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. Disconnect battery.
2. Disconnect wiring harness plug from coolant-temperature-sensor
(pic. I, 2).
3. Disconnect wiring harness plug from mass air flow meter (pic.
I, 4).
4. Remove cover wire channel (pic. I, 1).
5. Remove ribbed plastic tube from wiring harness (pic. I, 3).
6. Remove insulation tape from wiring harness.
7. Cut sensor cable in cable duct (shifted cuts) and remove
wiring harness plug sensor.
8. Hold new wiring harness sensor temporarily into position new
wiring harness sensor and measure.
Minimum cable length from beginning of plug to exit of cable
duct is 120 mm.
9. Assign, mark cable and install new connector (pic II).
10. Strip cable.
11. Slip heat-shrinkable tube on ground cable and crimp cable
ends with each other.
12. Slip heat-shrinkable tube on positive battery cable and crimp
cable ends with each other. Crimping connection of mass and
plus cable shall not be on the same position (shifted
position).
13. Slip heat-shrinkable tube on crimping ground cable and heat
up with hot air dryer.
14. Slip heat-shrinkable tube on crimping positive battery cable
and heat up with hot air dryer.
15. Route ribbed plastic tube from center cable duct around
wiring harness in direction cable branch sensor water
temperature approx. 30 mm. This is absolutely necessary since
the cable duct exit is sharply edged where it takes up the
ribbed plastic tube. Route wiring harness, insert ribbed
plastic tube into cable duct exit, install cover wiring
harness duct and secure with 2 cable binders. Minimum cable
length from beginning of plug to exit of cable duct is 120 mm
(maximum 140 mm).
16. Insulate wiring harness completely new and connect wring
harness plug mass air flow meter. Cable length from exit
cable duct to split coolant temperature-sensor shall not
exceed 30 mm.
17. Remove coolant-temperature-sensor and absorb draining coolant.
18. Install new coolant-temperature-sensor - torque to 18 Nm.
19. Connect new coolant-temperature-sensor electrically.
20. Check and correct coolant level.
21. Connect battery.
22. Program volatile memories.
