Checking cables and sensors
Check transmission speed sensor cable for power supply between control module #A59 and transmission connector #16 and between the transmission connector and the speed sensor connector for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
HINT: With control module connected and ignition on, the voltage between connector #1 and ground (breakout box #53) should be approximately 8-12 V.
Check speed sensor power supply between control module #A41 and automatic transmission connector #17 and between automatic transmission connector #17 and speed sensor connector for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
Remedy as necessary.
