Faults In Sensor Cable, 940
GF. Fault in sensor lead, 940New sensor lead position, 940 with Rex Regina engine management system and control module, p/no. 9130197
On cars with the Rex/Regina ignition/fuel system and an ABS control module, p/n9130197-8, with OBD system, interference can occur in the sensor lead to the left front wheel. Interference can cause symptoms such as pulsing in the brake pedal when the car is stationary and the engine RPM is above idle. Normal braking function is not affected. If symptoms occur, modify sensor lead as per figure GF2 below. This measure was introduced into production from chassis number:
944- 125305
945- 075946
With the introduction of control module, p/n 9128853 in April '93, the risk of interference was eliminated. The sensor lead is now routed (in production) to the left front wheel as before, see figure GF1 below.
If symptoms appear: Check that sensor lead follows the right route in the engine compartment.
GF1. Old sensor lead position
GF2. New sensor lead Position
When re-routing lead, make sure that lead is against wheelhouse plate.
Fix lead to existing hole in wheelhouse plate with clamps (p/no. 945611) and flanged bolt M8x12 (p/no. 949887).
Fit rear tie strip over connector.
