Checking Map Sensor Circuit:
Test NS-3A continued, Part 2 of 2.
1. Turn ignition OFF.
2. Disconnect the engine controller.
3. Disconnect the MAP sensor connector.
4. Using an external ohmmeter, measure the resistance of the VT/WT wire, (Figure 2).
- If the resistance is above 10 ohms, repair the wire, and perform Verification Test 1. Verification Test VER-1
- If the resistance is 10 ohms or less, go to step 5.
5. Check valve timing and compression.
- If the valve timing and comporession are within specifications, replace the MAP sensor.
- If the valve timing or compression is not within specifications, repair the engine as needed, and perform Verification Test 1. Verification Test VER-1
