Using a Scan Tool

HARNESS INSPECTION

STEP 1. Check for continuity of the ground circuit
-

Fuel lank differential pressure sensor connector: Disconnected

OK: GO TO STEP 2
NG: Repair the harness (A2 - 92)

STEP 2. Check for open-circuit, or short-circuit to ground between the engine control module and the manifold absolute pressure sensor.
-

Fuel tank differential pressure sensor connector: Disconnected

-

Engine control module connector: Disconnected

OK: GO TO STEP 3
NG: Repair the harness (A1 - 77)

STEP 3. Measure the sensor impressed voltage to the manifold absolute pressure sensor.
-

Fuel tank differential pressure sensor connector: Disconnected

-

Engine control module connector: Connected

-

Ignition switch: ON

Voltage (V): 4.8 - 5.2 V

OK: STOP
NG: Replace the engine control module.
