Intermediate Sensor Inspection - FS5A-EL




INTERMEDIATE SENSOR INSPECTION [FS5A-EL]

Wave Profile Inspection

1. Inspect the power supply circuit for the intermediate sensor.
a. Disconnect the intermediate sensor connector.

b. Turn the ignition switch to ON.

c. Measure the voltage at intermediate sensor connector terminal B (wiring harness side).






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

Intermediate sensor voltage
- 4.5-5.5 V

d. Turn the ignition switch off.

e. Connect the intermediate sensor connector.

2. Inspect the GND circuit for the intermediate sensor.
a. Turn the ignition switch off.

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






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

Intermediate sensor voltage
- 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 AC
- (-) lead: TCM terminal M
- Oscilloscope setting: 1 V/DIV (Y), 2.5 ms/DIV (X), DC range

b. Start the engine.

c. Inspect wave profile when vehicle speed at 30 km/h {20mph}.






- If there is any malfunction, perform the Visual Inspection.

Visual Inspection

1. Shift the selector lever to N position.

2. Remove the intermediate sensor.
a. Disconnect the negative battery cable.

b. Disconnect the intermediate sensor connector.

c. Remove the intermediate sensor from the transaxle case.

3. Verify that the sensor is free of any metallic shavings or particles.

- If there is any malfunction, clean them off.

4. Inspect sensor rotor surface via intermediate sensor installation hole while rotating the front tire manually.

- Is sensor rotor free of damage and cracks?
- Is sensor rotor free of any metallic shavings or particles?

- If sensor rotor is normal, replace the intermediate sensor. Intermediate Sensor Removal/Installation - FS5A-EL
- If there is any malfunction, clean or replace the sensor rotor.
