Key ON. Within VCM Live, open the ECT sensor DTC parameter, does the ECT sensor parameter display a voltage of 4.9 volts or greater? |
≥ 4.9 volts |
Go to Step 2 |
Intermittent Issue - Refer to Intermittent Diagnostics |
| 2 |
Key OFF. Disconnect the ECT sensor connector and jump cavities "A" & "B" together. Key ON. Does the ECT parameter display a voltage of 0.05 volts or less? |
|
Go to Step 3 |
Go to Step 7 |

Using a DVOM (Digital Volt-Ohm Meter) check the resistance between the two terminals of the ECT sensor and compare the resistance reading to the ECT Resistance & Temperature Reference Table above. Is the resistance value correct according to the reference table? |
See ECT Resistance & Temperature Reference Table |
Go to Step 5 |
Go to Step 4 |
| 4 |
Replace the ECT sensor. Is the replacement complete? |
|
Go to Step 13 |
N/A |
| 5 |
Inspect the ECT wire harness connector terminals "A" & "B" for damages, corrosion or contamination. Any issues found? |
|
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
Go to Step 6 |
| 6 |
Key OFF. Disconnect ECU wire harness connector "D". Inspect the ECU connector Pin 11 for corrosion or contamination. Any issues found? |
|
Repair the circuit as necessary and fix any pins with corrosion or contamination |
Intermittent Issue - Refer to Intermittent Diagnostics |
| 7 |
Jump the ECT signal cavity "B" connector to the engine ground. Does the VCM Live ECT parameter display a voltage of 0.5 volts or less? |
|
Go to Step 8 |
Go to Step 11 |
| 8 |
Key OFF. Disconnect the ECU "D" connector. Using a DVOM check for continuity between ECT sensor low reference cavity "A" and ECU SP3. Do you have continuity between them? |
|
Go to Step 9 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
| 9 |
Inspect all of the connector "D" pins for corrosion or contamination. Any issues found? |
|
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
Go to Step 10 |
| 10 |
Replace the ECU. Is the replacement complete? |
|
Go to Step 13 |
N/A |
| 11 |
Key OFF. Disconnect the ECU wire harness connector "D". Using a DVOM check for continuity between the ECT connector signal cavity "B" & ECU connector "D" pin 11. Do you have continuity between them? |
|
Go to Step 12 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
| 12 |
Inspect the ECU connector "D" pin 11 and SP3 pins for any corrosion or contamination. Any issues found? |
|
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
Go to Step 10 |
| 13 |
Clear any DTC from the ECU. Turn the ignition off and wait 30 seconds. Start the engine and operate the engine to full operating temperature. Observe the Check Engine Light on the Menu bar in VCM Live. After operating the engine within the test parameters, check for any stored codes. Does the engine operate without any stored DTCs? |
