Checking Cables and Sensors

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 Checking wiring and terminals. Permanent faults, a short-circuit to ground according to Checking wiring and terminals. Permanent faults and a short-circuit to supply voltage according to Checking wiring and terminals. 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 Checking wiring and terminals. Permanent faults , a short-circuit to ground according to Checking wiring and terminals. Permanent faults and a short-circuit to supply voltage according to Checking wiring and terminals. Permanent faults.

Remedy as necessary.
