DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
ENGINE (DIAGNOSTICS)
Step
CHECK HARNESS BETWEEN ECM AND
PRESSURE SENSOR CONNECTOR.
1)Turn the ignition switch to OFF.
2)Disconnecl the connector from ECM.
3)Measure the resistance of harness between
ECM and pressure sensor connector.

CHECK POOR CONTACT.
Check poor contact in pressure sensor con-
nector.
0 CHECK CURRENT DATA.
1)Turn the ignition switch to OFF.
2)Disconnect the connector from atmospheric
Check
Is the resistance less than 1
a?
Is the resistance less than 1
a?
Is there poor contact in pres-
sure sensor connector?
Is the value more than 140 kPa
(1,050 mmHg, 41.34 inHg)?
Yes
30 to step 8.
30 to step 9.
