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.
- (1) Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [MZR 1.8, MZR 2.0, MZR 2.5].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI].)
- (2) Disconnect the intermediate sensor connector.
-
- (3) Switch the ignition to ON. (engine off)
- (4) Measure the voltage at intermediate sensor connector terminal A (harness side).
-
-
• If there is any malfunction, repair wiring harness between intermediate sensor and TCM.

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

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: body GND
• Oscilloscope setting: 1 V/DIV (Y), 200 µs/DIV (X), DC range
- (2) Start the engine.
- (3) Measure the wave form when the following conditions are met.
