I want to replace the knock sensor on my 2003 honda crv where is it located on the engine the code for it came up when my check engine light came on and was tested
Just done this on a 2002 (mk2) CR-V with 2 litre ivtec petrol engine. The knock sensor is screwed into the engine block underneath the inlet manifold. The best access to it is by removing the inlet manifold but this takes time. I replaced it from below by:
1) remove the undertray that is fastened to the front bumper, to do this its two bolts and lots of plastic rivets - lever the centre pins out of the rivets and they will come out.
2) from underneath the car you can now see the knock sensor in the centre of the engine block, it has a 27mm AF hex and a cable going to it.
3) disconnect the cable from the knock sensor, it has a latch on the plug that needs to be pressed, if like me you can't reach to press the latch don't worry move on to the next step.
4) Get a large 27mm open end spanner and undo the knock sensor, if you wern't able to disconnect the cable in the previous step it is possible to take the sensor all the way out of the block with the cable still attached. It is then much easier to unlatch the cable.
5) to refit the new one you need small hands or better access - there is a plastic clip holding a cable to the engine on the left hand side of the engine I found that by removing this clip (a single 10mm bolt) I could move the bundle of cables and get better access to refit and connect the new knock sensor.
6) Fit the new knock sensor into the block, tighten it to the recommended torque (can't get a torque wrench in so just nip it up, do not overtighten).
7)reconnect the cable.
8) refasten the cable clip holding the bundle of cables you removed to get access.
9) refit undertray.
10) I don't have a code reset device and the check engine light was still on after this work but it went out after three complete engine cold,hot,cold cycles. and has stayed out since.
SOURCE: Engine light came on - yellow. Code: P0134 02
there is either a problem with the wiring going to the front oxygen sensor, or with the oxygen sensor itself. good luck!

These knock sensors are hard to get into. If thats a V6 it is underneath the intake manifold. make sure you cover the intake port when you take it apart, so a screw or a bolt don't accidentally drops in there.
SOURCE: Engine light is on and
What happens, is you get a check light on.
You have the code read for free
If you get the code,you replace something
not knowing the system your working on
and that codes don't tell you what to change
Your best bet is to always have a professional
shop with a data base, that can access anything
they need pertaining to your vehicle,diagnose and
repair it.
