That was a waste of time. The knock sensor's only function is to sense spark knock or internal noise and send a signal to the PCM which retards the ignition timing. It does not effect if the engine gets spark or not.

First you need to determine if your no start condition is fuel related or spark related. If it's spark related, you are going to want to scan the system to avoid swapping parts in the future as it will get quite costly. There are 4 components that will cause a no start condition. One being the cam sensor, the other a crank sensor, (some cars still have coils check for that) and the last an ignition module or ignitor as some cars have. (No spark issues).

If you have a fuel related problem, then you need to trouble shoot the fuel pump to make sure it's working, the filter isn't plugged, or that it isn't pumping too low of pressure to operate the injectors.

How do i change a knock sensor on a 1997 Nissan Altima?


Inspect/Test/Replace


A defective knock sensor may cause engine detonation or reduced spark advance and fuel economy. When a knock sensor is removed and replaced, the sensor must be tightened to its specified torque. If the knock sensor is installed tighter than it should be, it may become too sensitive and provide an excessively high voltage signal, resulting in more spark retard than required. When the knock sensor is installed looser than it should be, the knock sensor signal will be lower than normal, resulting in engine detonation.

To replace the knock sensor:


  • Disconnect the knock sensor wiring connector.

  • Then, unscrew the sensor.

  • Remove the knock sensor.

  • Reverse the procedures to install the part.

It is possible that damage will be done if you allow the vehicle to continue with those faults. Not so much the EGR, although that will reduce Gas Mileage, but the Knock sensor is part of the engine firing circuit and can cause the vehicle to fire the plugs in the wrong order. The knock sensor works with the cam position sensor to make sure the timing stays correct. It detects spark plug detonation.
