INSPECT INSTALLATION OF COOLANT CONTROL VALVE
- Inspect installation of coolant control valve.
- Is the coolant control valve installed securely?
|
Yes |
Go to the next step. |
| No |
Retighten the coolant control valve, then go to Step 7.
(See COOLANT CONTROL VALVE REMOVAL/INSTALLATION [VIN M]
). |

INSPECT COOLANT CONTROL VALVE CIRCUIT FOR SHORT TO GROUND
- Verify that the coolant control valve/coolant control valve position sensor and PCM connectors are disconnected.
- Inspect for continuity between the following terminals (wiring harness-side) and body ground:
- Coolant control valve/coolant control valve position sensor terminal A
- Coolant control valve/coolant control valve position sensor terminal B
- Coolant control valve/coolant control valve position sensor terminal C
- Coolant control valve/coolant control valve position sensor terminal D
- Coolant control valve/coolant control valve position sensor terminal E
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- Coolant control valve/coolant control valve position sensor terminal A-PCM terminal 1CW
- Coolant control valve/coolant control valve position sensor terminal B-PCM terminal 1CX
- Coolant control valve/coolant control valve position sensor terminal C-PCM terminal 1D
- Coolant control valve/coolant control valve position sensor terminal D-PCM terminal 1I
- Coolant control valve/coolant control valve position sensor terminal E-PCM terminal 1BG
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to power supply.
Go to Step 7. |
| No |
Go to the next step. |

INSPECT COOLANT CONTROL VALVE/COOLANT CONTROL VALVE POSITION SENSOR CIRCUITS FOR SHORT TO EACH OTHER
- Verify that the coolant control valve/coolant control valve position sensor and PCM connectors are disconnected.
- Inspect for continuity between coolant control valve/coolant control valve position sensor terminals A, B, C, D and E (wiring harness-side).
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- Coolant control valve/coolant control valve position sensor terminal A-PCM terminal 1CW
- Coolant control valve/coolant control valve position sensor terminal B-PCM terminal 1CX
- Coolant control valve/coolant control valve position sensor terminal C-PCM terminal 1D
- Coolant control valve/coolant control valve position sensor terminal D-PCM terminal 1I
- Coolant control valve/coolant control valve position sensor terminal E-PCM terminal 1BG
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to each other.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to each other.

INSPECT COOLANT CONTROL VALVE CIRCUIT FOR OPEN CIRCUIT
- Verify that the coolant control valve/coolant control valve position sensor and PCM connectors are disconnected.
- Inspect for continuity between the following terminals (wiring harness-side):
- Coolant control valve/coolant control valve position sensor terminal A-PCM terminal 1CW
- Coolant control valve/coolant control valve position sensor terminal B-PCM terminal 1CX
- Coolant control valve/coolant control valve position sensor terminal C-PCM terminal 1D
- Coolant control valve/coolant control valve position sensor terminal D-PCM terminal 1I
- Coolant control valve/coolant control valve position sensor terminal E-PCM terminal 1BG
- Is there continuity?
|
Yes |
Go to the next step. |
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- Coolant control valve/coolant control valve position sensor terminal A-PCM terminal 1CW
- Coolant control valve/coolant control valve position sensor terminal B-PCM terminal 1CX
- Coolant control valve/coolant control valve position sensor terminal C-PCM terminal 1D
- Coolant control valve/coolant control valve position sensor terminal D-PCM terminal 1I
- Coolant control valve/coolant control valve position sensor terminal E-PCM terminal 1BG
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has an open circuit.
