- If connections are OK, check that transfer oil temperature sensor signal circuit (A1) and transfer oil temperature sensor ground circuit (A2) are as follows.
- Resistance of "A1" and "A2" circuits: less than 1 Ω
- Resistance between "A1" circuit and ground: infinity
- Resistance between "A1" circuit terminal and other terminal at transfer oil temperature sensor connector: infinity
- Voltage of "A1" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition? |
Go to Step 3. |
