62-576 DIAGNOSIS-ENGINE CONTROL SYSTEM

Is the inspection result normal?
YES>To step 3。
No >Maintenance related faults.

3. Check the signal circuit of intake phase sensor.

(a). Ignition switch: LOCK。
(b). Disconnect the battery negative cable.
(c). Disconnect the intake phase sensor connectorE52andthe ECUconnectorE01
respectively.

(d). Measure the resistance between the inlent
position sensor E52 pin 2 and the ECU
connector E01 pin 53.
Standard resistance:

Connect the pin by Standard value
pmultimeter

E52(2)-E01(53) Approx 0Ω

Is the inspection result normal?
YES>To step 4。
No > Repair or replace the wiring harness of inlent phase sensor.

4. Check the power circuit of crankshaft intake air phase sensor

(a). Ignition switch: LOCK。
(b). Disconnect the battery negative cable.
(c). Disconnect the intake phase sensor connector E52 respectively.
(d). Ignition switch: ON。

(e). Measure the voltage between the inlent
position sensor E52 pin 1 and the ECU
connector.
Standard voltage:

Connect the pin by Standard value
pmultimeter

E52(1)-Grounding Approx 5V

Is the inspection result normal?
YES>To step 5。
No > Repair or replace the wiring power source harness of inlent phase sensor.
