DIAGNOSTICS - ENGINE CONTROL SYSTEM 04-81

(f) Use a multimeter to measure the resistance 04
between the pin 2, 3 of the atmospheric
pressure sensor connector E20 and the
ground.

Standard resistance

Multimeter connection
Standard value
pin
E20（2）- ground ＞ 10 MΩ

E02（3）- ground ＞ 10 MΩ

Is the inspection result normal?
YES>To step 4.
No > Maintain or replace the harness.

4 . Replace atmospheric pressure sensor
(a) Replace atmospheric pressure sensor.
(b) Use a diagnostic apparatus to perform DTC verification procedures.
(c) Implement the steps to read sensor data stream.
(d) Check whether DTC exists.
Is the inspection result normal?

YES> Replace atmospheric pressure sensor
NO >To step 5.

5 . Replace ECM

(a) Replace ECM.
(b) Use a diagnostic apparatus to perform DTC verification procedures.
(c) Implement the steps to read sensor data stream.
(d) Verify that no DTC exists and the data are normal.
