DIAGNOSIS-ENGINE CONTROL SYSTEM 62-577

5. Check the ground circuit of intake phase sensor

(a). Ignition switch: LOCK。
(b). Disconnect the battery negative cable.
(c). Disconnect the intake phase sensor connector E52 respectively.。
62
(d). Measure the resistance between the inlent
position sensor E52 pin 3 and the ECU
connector.
Standard resistance:

Connect the pin by Standard value
pmultimeter

E52(3)-Grounding Approx 0Ω

Is the inspection result normal?
YES>To step 6。
No >Repair or replace the wiring GND harness of inlent phase sensor.

6. Replace and check the intake air phase sensor

(a). Replace the intake phase sensor.
(b). Using the diagnostic tool performs the DTC confirmation procedure.
(c). Perform the step of reading the sensor data stream. Indentify whether the check
result is normal or not.

Is the inspection result normal?
YES>Replace the intake phase sensor.

No >To step 7。

7. Check the signal panel of intake phase sensor

(a). Ignition switch: LOCK。
(b). Check whether the signal panel is looser damaged; whether the surface of the
signal panel has a foreign body.
(c). Check the intake phase sensor mounting clearance. Clean the foreign body; replace
the damaged signal plate.
Standard clearance:

Clearance Standard value

Signal panel of intake phase sensor 0.3~1.5mm
