DTC P0328 - Knock Bank 1 Sensor Circuit High

Conditions for setting dtc P0328

￭

Engine Running

￭

Knock Bank 1 Sensor ≥ 4.9 volts

￭

The above must be present for a period of 128 instances/cycles or greater to trigger DTC P0328

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 4.9 volts or higher?	≥ 4.9 volts	Go to Step 2	Intermittent Issue (Refer to Intermittent Diagnostics)
2	- Key OFF - Disconnect the Knock 1 sensor connector and the ECU harness connector "D" - Using a DVOM check for continuity between the Knock 1 sensor signal 1 cavity "A" (for both Drive-By-Cable & Drive-By-Wire harnesses) & the ECU connector "D" pin 1 (for both Drive-By-Cable & 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 1 sensor connector and the ECU harness connector "D" - Using a DVOM check for continuity between the Knock 1 sensor signal 2 cavity "B" (for Drive-By-Cable harness) cavity "B" is the low reference signal (for drive-By-Wire) & the ECU connector "D" pin 8 (for both Drive-By-Cable harness) & C19-B(for 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 1 sensor - Is the replacement complete?		Go to Step 5	N/A
5	- 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 store codes - Does the engine operate without any stored DTC's?		System is now operational and ready to be tuned	Contact HP Tuners Support
