Knock sensor code po325

Recommended Posts

Hi All

 anyone out there suffered code po325 knock sensor on v6 3ltr 2004 Alphard? 
I’ve got just 41500 miles on clock and that’s the code that’s come out .

I have had a AC Stag gas conversion done just 500 mls ago and simply wondered could there be a link to that or not? 
thank you in advance for any information regarding this subject.

Hi lpg conversion would not affect knock sensors it's just wear and tear there are 2 knock sensors get both done at same time you will need 3 gaskets there are kits on ebay if you want item no. Let me know and will find it for you best to replace wire harness at same time as they get brittle from the heat .

I’m getting both done , they’re not too expensive either but it’s the labour that spoils the pot! But it has to be done and I’ll call my garage in the morning ref wiring harness too .

many thanks for the sound advice
