DTC Troubleshooting

NOTE
Before this trouble shooting is performed, read the precautions for DTC troubleshooting referring to 
“Precautions for DTC Troubleshooting”.

 

Step

Action

Yes

No

1

Was “Engine and Emission Control System Check” 
performed?

Go to Step 2.

Go to “Engine and 
Emission Control 
System Check”.

2

CKP sensor and connector for proper installation check

Is CKP sensor installed properly and connector connected 
securely?

Go to Step 3.

Correct.

3

CKP sensor power supply voltage check
1) Disconnect connector from CKP sensor with ignition 

switch turned OFF.

2) Check for proper terminal connection to CKP sensor and 

ECM connectors.

3) If connections are OK, turn ignition switch to ON 

position.

4) Check that CKP sensor power supply voltage is battery 

voltage between CKP sensor connector and vehicle 
body ground.

Is it in good condition?

Go to Step 4.

Repair or replace CKP 
sensor power supply 
circuit.

4

Wire harness check
1) Turn ignition switch OFF position.
2) Disconnect connector from ECM.
3) Check that CKP sensor circuit is as follows.

• Wiring harness resistance of CKP sensor signal circuit 

is less than 3 

Ω.

• Insulation resistance of each CKP sensor signal and 

ground circuit between CKP sensor connector and 
vehicle body ground is infinity.

• Insulation resistance of wire harness is infinity 

between CKP sensor signal terminal and each other 
terminal at CKP sensor connector.

• Circuit voltage of each CKP sensor signal circuit and 

ground circuit is 0 – 1 V with ignition switch turned 
ON.

Are they in good condition?

Go to Step 5.

Repair or replace 
defective wire harness.

5

CKP sensor signal circuit voltage check
1) Check that CKP sensor signal circuit voltage is 5 V 

between CKP sensor connector and vehicle body 
ground.

Is it in good condition?

Go to Step 6.

Substitute a known 
good ECM and recheck.

6

CKP sensor check
1) Check CKP sensor and sensor rotor referring to 

“Camshaft Position (CMP) Sensor and Crankshaft 
Position (CKP) Sensor Inspection in Section 1C”.

Are they in good condition?

Go to Step 7.

Replace CKP sensor 
and/or sensor rotor.

4) Check DTC by using scan tool.

DTC Troubleshooting

7

CMP sensor and its circuit check
1) Check CMP sensor and its circuit referring to Step 2 to 6 

of “DTC P0340: Camshaft Position Sensor Circuit”.

Are they in good condition?

Substitute a known 
good ECM and recheck.

Repair or replace.

Step

Action

Yes

No

DTC detecting condition

Trouble area

CKP sensor outputs signal of less than 10 pulses for continuous 3 times within 
CKP no-teeth reference signal (120

° crank angle).

• CKP sensor and/or sensor rotor
• ECM

Step

Action

Yes

No

1

Was “Engine and Emission Control System Check” 
performed?

Go to Step 2.

Go to “Engine and 
Emission Control 
System Check”.

2

CKP sensor and connector for proper installation check
1) Turn ignition switch to OFF position.
2) Check for proper terminal connection to CKP sensor and 

ECM connectors.

3) If connections are OK, check CKP sensor for installation 

condition.

Is CKP sensor installed properly?

Go to Step 3.

Repair.

3

CKP sensor check
1) Check CKP sensor and sensor rotor referring to 

“Camshaft Position (CMP) Sensor and Crankshaft 
Position (CKP) Sensor Inspection in Section 1C”.

Are they in good condition?

Substitute a known 
good ECM and recheck.

Replace CKP sensor 
and/or sensor rotor.
