Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for choosing Just Answer.
Do you have the specific codes that you pulled from the diagnostic?
Thank you. If you are getting the P0328 you should replace the knock sensor. I would hold off on the IAT, first change the knock sensor (common sensor that goes out) reset the codes and see if the p127 comes back.
Trouble Code: P0328 Knock Sensor Circuit High Input (Bank 1)
Actually that is the only way to test it manually.
Start engine and run at idle.
Measure voltage at ECM pin 64.
Voltage should be approximately 2.4 vDC.
The way we would measure it here at the shop is by doing a freeze data on the car.
