Delphi AS10263 Knock Sensor

Was getting 0325 code indicating bad knock sensor. Checked with Honda and they wanted $255 plus tax for theirs (which could be a rebranded Delphi or NGK). Anyway bought this from Amazon for 30% of that and had it installed. Works perfect. No CEL. By the way, (like the oil filter) its in a really dumb place, in this case behind the starter and you can't actually see it without a mirror, so getting it out involves fishing, cursing, bandaids and wasting a lot of time. The local garage charged an hours labour which is a much better idea than trying to do it yourself - trust me!

Took care of P0325 on Acura RDX. 1¹/¹⁶" Deep socket Short extension or 2 and ratchet with flex head is all that's needed, don't have to remove anything to get this replaced but the pigtail lead attached to it. If you still have an issue you need to check the wiring because this is dead simple single wire plug and sensor that grounds through the block. The only non Acura brand I would trust is Delphi or NTK for this application because most likely one of these two are the OEM supplier for Acura and this was $40ish shipped compared to $130ish shipped from online Acura dealer.

I really disliked changing this sensor more than once. You have to remove the intake plenum on the 2006 and 2007 honda accord to replace this part. The first time i replaced the original with the delphi the check engine light went off for. I drove to work a couple times and it came back on. I removed he intake plenum and double checked the that it was torqued to 16 ft-lbs and it was. I replaced with a honda knock sensor and it do not have a check engine light code for a faulty knock sensor,.

Just got an engine check and its my knock sensor again. After a year, it broke. It has no resistance but by knock test, it doesn’t produce any voltage..

My mechanic installed it on my 09 Honda crv and worked no issues since.
