1 |
- Key ON - Within VCM Live, open the ECT sensor DTC parameter, does the ECT sensor parameter display a voltage of 0.1 volts or less? |
≤ 0.1 volts |
Go to Step 2 |
Intermittent Issue (Refer to Intermittent Diagnostics) |
|
2 |
- Key OFF - Disconnect the ECT sensor connector - Key ON - Does VCM Live ECT parameter display 4.9 volts or greater? |
|
Go to Step 3 |

|
3 |
- Replace the ECT sensor - Is the replacement complete? |
|
Go to Step 7 |
N/A |
|
4 |
- Key OFF - Disconnect the ECU wire harness connector "D" - Check for continuity between ECT sensor connector signal cavity "B" and ECU signal connector "D" pin 11 - Do you have continuity between them? |
|
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
Go to Step 5 |
|
5 |
- Check for continuity between ECT sensor connector cavity "A" & ECU ground C28-A - Do you have continuity between them? |
|
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
