Diagnostic Steps🔗
| Step | Action | Value (s) | YES | NO |
|---|---|---|---|---|
| 1 | - Key on, Engine running - Within VCM Live, open the knock sensor DTC parameter, does the knock sensor parameter display 0.1 volts or less? |
Go to Step 2 | Intermittent Issue — Refer to Intermittent Diagnostics | |
| 2 | - Key OFF - Disconnect the Knock 2 sensor connector and the ECU harness connector "D" - Using a DVOM check for continuity between the Knock 2 sensor signal cavity "A" (for Drive-By-Wire Harness) & the ECU connector "D" pin 8 (for Drive-By-Wire harnesses) - Do you have continuity between them? |
Go to Step 3 | Repair the circuit as necessary, locate any wires that need to be repaired or replaced | |
| 3 | - Key OFF - Disconnect the Knock 2 sensor connector and the ECU harness connector "D" - Using a DVOM check for continuity between the Knock 2 sensor low reference 2 cavity "B" (for Drive-By-Wire harness) & the ECU connector "D" pin SP3 (for both Drive-By-Wire harness) - Do you have continuity between them? |
Go to Step 4 | Repair the circuit as necessary, locate any wires that need to be repaired or replaced | |
| 4 | - Replace Knock 2 sensor - Is the replacement complete? |
