ec5780 Posted December 17, 2022 Share Posted December 17, 2022 (edited) Hello Just wanted to share my experience. 2006 Honda FR-V, 2.0L petrol. Started to get this code coming up. At first I ignored it for a while hoping it was a one-off (there was also another possibly unrelated fault as well that was also causing the yellow light to come on). I decided to investigate it so I had the mechanic reset it and within 15mins it had already come back on again, before I had even gone home. Seeing that the part from Honda costs around £150 I ordered this one from eBay and asked my mechanic to fit it. Two days later the light came back on again. I am not sure that the above is as genuine as it seemed, so I decided to bite the bullet and buy one directly from Honda and hope for the best. Sent the one back from eBay and received a prompt refund, and so far all good with the new one. Only loss really is that I've had to pay the mechanic to do the job twice.

Trevor Posted December 21, 2022 Share Posted December 21, 2022 What was the lamp and also do you have any information of the fault code generated? Quote Link to comment Share on other sites More sharing options...
ec5780 Posted December 21, 2022 Author Share Posted December 21, 2022 (edited) Quote What was the lamp Do you mean which warning light? It was the yellow 'engine malfunction light' which looks like the outline of an engine The fault code was as per the thread title, except I got two digits swapped round, it should have been: P0325 Knock Sensor 1 No Signal Edited December 21, 2022 by ec5780 clarify and update with response to the question Quote Link to comment Share on other sites More sharing options...
Trevor Posted December 23, 2022 Share Posted December 23, 2022 Sorry, serves me right for not reading the title correctly Sometimes, knock sensor signals can become corrupted by electrical interference and a classic one for causing this is stray High Tension lead/coils breaking down and leaking HT into the wiring loom (especially if in the immediate vicinity) Also, check the fuel octane you're using and maybe jump to 98 Super Unleaded to see if this makes a difference on the engine knock Quote Link to comment Share on other sites More sharing options...
ec5780 Posted December 25, 2022 Author Share Posted December 25, 2022 Thanks. In this case, replacing the sensor (2nd time, with the genuine one as I mentioned in my first post) seems to have done the trick but it's good to know about the potential issue with HT Leads. 1 Quote Link to comment Share on other sites More sharing options...
eddie42 Posted April 27, 2023 Share Posted April 27, 2023 I have the same exact issue, I've replaced the knock sensor twice whith an after market sensors but the light continues to persist. I'm not in the position to purchase a genuine part so I've just been drive for a while whith the light on, bit the car now hesitates when pulling of and my mpg display 26mpg average.

iceman2010 Posted August 27, 2023 Share Posted August 27, 2023 I had the same issue and replaced with a genuine part and the light hasn’t been on since. 1 Quote Link to comment Share on other sites More sharing options...
JimmyD82 Posted January 11 Share Posted January 11 (edited) I have the same problem and the aftermarket part is not working for me either 😞 I'll order a knock sensor from Honda then!! Edited January 11 by JimmyD82 1 Quote Link to comment Share on other sites More sharing options...
