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 the ECM terminals, such as the ground.

: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

Diagnostic Procedure

UBS00DJR

1. 

RETIGHTEN GROUND SCREWS

1.

Turn ignition switch OFF.

2.

Loosen and retighten engine ground screws.

>> GO TO 2.

2. 

CHECK CKP SENSOR (OBD) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Disconnect crankshaft position (CKP) sensor (OBD) and ECM
harness connectors.

2.

Check continuity between ECM terminal 47 and sensor terminal
2. Refer to Wiring Diagram.

3.

Also check harness for short to ground and short to power.

OK or NG

OK

>> GO TO 4.

NG

>> GO TO 3.

3. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors F38, F102

●

Harness for open or short between ECM and crankshaft position sensor (OBD)

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

4. 

CHECK CKP SENSOR (OBD) GROUND CIRCUIT FOR OPEN AND SHORT

1.

Reconnect ECM harness connector.

2.

Check harness continuity between sensor terminal 1 and engine ground. Refer to Wiring Diagram.

3.

Also check harness for short to power.

OK or NG

OK

>> GO TO 6.

NG

>> GO TO 5.

5. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors F38, F102

●

Harness for open between crankshaft position sensor (OBD) and ECM

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

6. 

CHECK CRANKSHAFT POSITION SENSOR (OBD)

1.

Disconnect crankshaft position sensor (OBD) harness connector.

2.

Loosen the fixing bolt of the sensor.

3.

Remove the sensor.

4.

Visually check the sensor for chipping.

5.

Check resistance as shown in the figure.

OK or NG

OK

>> GO TO 7.

NG

>> Replace crankshaft position sensor (OBD).

Continuity should exist.
