Intermediate Sensor Inspection

INTERMEDIATE SENSOR INSPECTION [FS5A-EL]

CAUTION:
- Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.

On-Vehicle Inspection

1. Inspect the power supply circuit for the intermediate sensor.
a. Set the battery and battery tray out of the way. Removal and Replacement

b. Disconnect the intermediate sensor connector.






c. Switch the ignition to ON (engine off).

d. Measure the voltage at intermediate sensor connector terminal A (harness-side).






- If there is any malfunction, repair wiring harness between intermediate sensor and TCM.

Intermediate sensor specification
- B+

e. Switch the ignition to off (LOCK).

f. Connect the intermediate sensor connector.

2. Inspect the GND circuit for the intermediate sensor.
a. Switch the ignition to off (LOCK).

b. Measure the voltage at intermediate sensor connector terminal C (harness-side).






- If there is any malfunction, repair wiring harness between intermediate sensor and TCM.

Intermediate sensor specification
- Below 1.0 V

3. Inspect the signal circuit for the intermediate sensor.
a. Connect the oscilloscope to the following TCM connector terminals and set it as below.

- (+) lead: TCM terminal 2L
- (-) lead: battery negative terminal
- Oscilloscope setting: 1 V/DIV (Y), 200 Microsecond/DIV (X), DC range

b. Start the engine.

c. Measure the wave form when the following conditions are met.

- Vehicle speed: 30 km/h {19 mph}
- Gear position: 3 GR





- If there is any malfunction, replace the intermediate sensor. Intermediate Sensor Removal/Installation
