Specification data are reference values and are measured between each terminal and ground.
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.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
Diagnostic Procedure

3.
CHECK 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.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 5.
NG
>> GO TO 4.
4.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors M71, F45
●
Harness for open or short between camshaft position sensor (PHASE) and ECM
●
Harness for open or short between camshaft position sensor (PHASE) and ECM relay
>> Repair open circuit or short to ground or short to power in harness or connectors.
5.
CHECK CMP SENSOR (PHASE) GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch “OFF”.
2.
Disconnect ECM harness connector.
3.
Check harness continuity between ECM terminal 29 and CMP sensor (PHASE) terminal 1.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 6.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
6.
CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Check harness continuity between ECM terminal 14 and CMP sensor (PHASE) terminal 2.
Refer to Wiring Diagram.
2.
Also check harness for short to ground or short to power.
OK or NG
OK
>> GO TO 7.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.

>> Replace camshaft position sensor (PHASE).
8.
CHECK CAMSHAFT (INTAKE)
Check the following.
●
Accumulation of debris to the signal plate of camshaft rear end
●
Chipping signal plate of camshaft rear end
OK or NG
OK
>> GO TO 9.
NG
>> Remove debris and clean the signal plate of camshaft
rear end or replace camshaft.
