DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
No.
7 CHECK HARNESS BETWEEN ECM AND
PRESSURE SENSOR CONNECTOR.
1) Turn ignition switch to OFF.
2) Disconnect connector from ECM.
3) Measure resistance of harness between
ECM and intake manifold pressure sensor
connector.
Connector & terminal
(B135) No. 19 — (E21) No. 2:
8 CHECK HARNESS BETWEEN ECM AND
PRESSURE SENSOR CONNECTOR.
Measure resistance of harness between
intake manifold pressure sensor connector
and engine ground.
Connector & terminal
(E21) No. 1 — Engine ground:
9 CHECK POOR CONTACT.
Check poor contact in pressure sensor con-
nector.
Step
Is the resistance less than
1 Ω?
Is the resistance more than
1 MΩ?
Is there poor contact in
pressure sensor connec-
tor?
EN(DOHC TURBO)-117
Check Yes
Go to step 8.
Go to step 9.
Repair poor con-
tact in pressure
sensor connector.
Engine (Diagnostics)
No
Repair open cir-
cuit in harness
between ECM
