Was "Engine and Emission Control System Check" performed? |
Go to Step 2. |
Go to ENGINE AND EMISSION CONTROL SYSTEM CHECK:J24B . |
| 2 |
DTC check
- Check DTC.
Is there DTC(s) other than P0335? |
Go to applicable DTC (s). |
Go to Step 3. |

CKP sensor power supply circuit check
- Turn OFF ignition switch and disconnect connector from CKP sensor.
- Check for proper terminal connection to CKP sensor connector.
- If connections are OK, turn ignition switch to ON position.
- Check that CKP sensor power supply circuit (B1) is battery voltage.
Is it good condition? |
Go to Step 4. |
Repair or replace defective wire harness. |

CKP sensor signal circuit and ground circuit check
- Turn OFF ignition switch and disconnect connectors from ECM.
- Check for proper terminal connection to ECM connectors.
- If connections are OK, check that CKP sensor signal circuit (B2) and ground circuit (B3) are as follows.
- Wiring harness resistance of each CKP sensor signal circuit and ground circuit is less than 3 Ω.
- Insulation resistance between CKP sensor signal circuit and vehicle body ground is infinity.
- Insulation resistance of wire harness is infinity between CKP sensor signal circuit terminal and each other terminal at CKP sensor connector.
- Insulation resistance of wire harness is infinity between CKP sensor ground circuit 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 in ON position.
Are they in good condition? |
Go to Step 5. |
Repair or replace defective wire harness. |

CKP sensor and sensor plate check
- Check CKP sensor and sensor plate.
Are they in good condition? |
Substitute a known-good ECM and recheck. |
Replace defective parts. |
