P0328 Mazda -

Question

Hi,

Have a P0328 problem on a mazda 2. Have replaced the Knock sensor and it is still displaying the fault. Is there anything else I can do?

Thanks

Answer 1

P0328 Knock sensor circuit high input

Circuit high input mean it is disconnected this can be from the harness pin to the sensor itself, what you need to do is measure the knock sensor voltage harness with the sensor disconnected key on engine of the voltage should be about 2.4 volts ,
