(5)  Switch the ignition to OFF.

(6)  Connect the intermediate sensor connector.

2.  Inspect the GND circuit for the intermediate sensor.

(1)  Switch the ignition to OFF.

(2)  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.

(1)  Connect the oscilloscope to the following TCM connector terminals and set it as below.

•  (+) lead: TCM terminal 2L

•  (-) lead: TCM terminal 1P

•  Oscilloscope setting: 1 V/DIV (Y), 2.5 ms/DIV (X), DC range

(2)  Start the engine.

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

•  If there is any malfunction, perform the Visual Inspection. (SeeVisual Inspection.)

Visual Inspection

1.  Shift the selector lever to N position.

2.  Remove the intermediate sensor.

(1)  Disconnect the negative battery cable.

(2)  Remove the battery and battery tray.

(3)  Disconnect the intermediate sensor connector.

(4)  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.

(1)  Is sensor rotor free of damage and cracks?

(2)  Is sensor rotor free of any metallic shavings or particles?

•  If sensor rotor is normal, replace the intermediate sensor. (SeeINTERMEDIATE SENSOR REMOVAL/INSTALLATION [FS5A-EL].)

•  If there is any malfunction, clean or replace the secondary gear.
