Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

2.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Loosen and retighten two ground screws on the body. Refer to

EC-159, "Ground Inspection"

.

OK or NG

OK

>> GO TO 3.

NG

>> Repair or replace ground connections.

3.

CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY CIRCUIT

1.

Disconnect camshaft position (CMP) sensor (PHASE) harness connector.

2.

Turn ignition switch ON.

3.

Check voltage between CMP sensor (PHASE) terminal 3 and
ground with CONSULT-II or tester.

OK or NG

OK

>> GO TO 5.

NG

>> GO TO 4.

4.

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors E12, F3

●

Harness for open or short between CMP sensor (PHASE) and ECM

●

Harness for open or short between CMP sensor (PHASE) and IPDM E/R

>> Repair open circuit or short to ground or short to power in harness or connectors.
