Intermediate Sensor Inspection - FS5A-EL

INTERMEDIATE SENSOR INSPECTION [FS5A-EL]

On-Vehicle Inspection

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






b. Turn the ignition switch to the ON position.

c. 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
- 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 (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), 2 ms/DIV (X), DC range

b. Start the engine.

c. Measure the wave form when vehicle speed at 30 km/h {19 mph}.






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