Install knock sensor 98 subaru 2.5 - 1994 Subaru Legacy Outdoor

if the engine has a knock sensor it is attached to the block between cylinders on the outside.

You replaced the knock sensor and not the fuel pump?? Change the fuel pump.

this code means Knock Sensor Low Input. This answer comes for Subaru Codes and Definitions. Hope this helps you

go have your catalatic converter checked, it may be plugged causing your car to suffocate when you accelerate

Replace knock sensor.

Hiya,

Here you go:

2.5L Engine To Remove:

1. Disconnect the battery ground cable.
2. Remove the air cleaner housing.
3. Vehicles with 5-spd transmission: Remove the clutch slave cylinder and set aside.
4. Disconnect the knock sensor wire harness retainer from the coolant hose.
5. Disconnect the knock sensor (KS) wire connector.
6. Remove the mounting bolt and knock sensor from the engine block.

Hope this helps...

Cheers,

the knock sensor itself can be faulty if there is a code showing for it.

CEL lights only come on if a sensor fails its diagnostic, it is nothing to do with the particular sensors readings, but telling you the sensor itself is bad.

The knock sensor is a little microphone attached directly to the cylinder block side wall.

As far as there being no knock sensor on a 99 2.2 I beg to differ. I have a 99 legacy and just had a diagnostic done and mine is bad. If there is no knock sensor why would it say it was bad and why does Auto Zone, Advanced Auto and my local Subaru dealer sell them. Mine is located under the throttel body and they are rather hard to get to. No offence to who ever said ther is no knock sensor but maby you should recheck your information becuse I know there is a knock sensor since I just changed mine.

at the top of the block under the plenum runners.
please leave feedback
cheers
