Hi guys, i started my car up this morning and my CEL lamp illuminated straight away and stayed on for about a mile, it went out but when i started the engine later today the CEL lamp was on again. I carried out a flash code readout and it was indicating a knock sensor fault. Is there a way to test the sensor, i know from Subaru the little knock sensor is nearly £180 Has anyone else come across this fault on theres?? I'm going to try and clean the terminals and check the wiring just in case. Cheers. Daz

 

Had mine changed 2 years back by a "Subaru Specialist" for about £85, never had any problem since. They're PC diagnostics will get crazy reading's from it if it's gone dicky.

 

That sounds cheap, i think Subaru might of priced the wrong part! Thanks for that mate.

 

got mine from subaru last year cost 118 inc vat fitted myself i tested mine by bolting it to the inlet manifold and no cel this was suggested by a mechanic friend of mine and worked

 

had the same problem,got a quote for new from subaru at £115,then found second hand for £20,fitted myself and has been fine ever since .

 

All sorted guys, cheers for your help. I got one from subaru 4 u, it only cost £75 for the genuine sensor. All faults cleared, weeeheee!!
