DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Engine speed check
1)Check that engine speed is correct referring to Engine Speed Check:D16AA.
Is check result OK?
|
Go to Step 3.
|
Repair or replace defective part(s).
|
| 3 |
CMP sensor power supply circuit and ground circuit check
1)When ignition is “OFF”, disconnect CMP sensor connector.
2)Check for proper terminal connection to CMP sensor connector.
3)If connections are OK, set ignition “ON”.
4)Check that voltage between “B1” and “B3” circuits is approx. 5 V.
Is check result OK?
|
Go to Step 6.
|
Go to Step 4.
|
| 4 |
CMP sensor ground circuit check
1)Check that voltage between “B1” circuit and ground is approx. 5 V.
Is check result OK?
|
Repair “B3” circuit.
If DTC is detected again, replace ECM and recheck DTC.
|
Go to Step 5.
|
| 5 |
CMP sensor power supply circuit check
1)When ignition is “OFF”, disconnect “D01” connector from ECM.
2)Check for proper terminal connection to “D01” connector.
3)If connections are OK, check the following points.
•Resistance of “B1” circuit: less than 1 Ω
•Resistance between “B1” circuit and ground: infinity •Resistance between “B1” circuit terminal and other terminal at CMP sensor connector: infinity •Voltage of “B1” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Replace ECM and recheck DTC.
|
Repair or replace defective wire harness.
|

CMP sensor signal circuit check
1)When ignition is “OFF”, disconnect “D01” connector from ECM.
2)Check for proper terminal connection to “D01” connector.
3)If connections are OK, check the following points.
•Resistance of “B2” circuit: less than 1 Ω
•Resistance between “B2” circuit and ground: infinity •Resistance between “B2” circuit terminal and other terminal at CMP sensor connector: infinity •Voltage of “B2” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 7.
|
Repair or replace defective wire harness.
|
| 7 |
CMP sensor check
1)Check CMP sensor.
Is check result OK?
|
Replace ECM and recheck DTC.
|
Replace CMP sensor.
