DTC P0340, P0345 CMP SENSOR (PHASE)

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

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.

Diagnosis Procedure

INFOID:0000000001326154

1.

CHECK STARTING SYSTEM

Turn ignition switch to START position.

Yes or No

Yes

>> GO TO 2.

No

>> Check starting system. (Refer to 

SC-8

.)

2.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Loosen and retighten ground screw on the body. Refer to 

EC-144, "Ground Inspection"

.

OK or NG

OK

>> GO TO 3.

NG

>> Repair or replace ground connections.

3.
