looking for some advice, check engine light keeps coming on and off and restricting boost fault code says knock sensor,now ive just replaced my maf today due to old one being crap now she idles sweet but i was sort of hopeing that it may of got rid of the knock problem but no if anything it comes on more now.
im gona buy new senor soon but is there any safety mearsures i can take till then also where abouts is the knock sensor located on the engine.
cheers dan.

 

 

Knock sensor is under the intercooler.
I would get a new knock sensor ASAP and take it easy while driving IE as little boost as possible, not worth the risk of a hole in the engine for sake of a cheapish sensor

 

ive been quoted 101£ at the dealers but does any 1 know of a cheaper sensor thats any good

 

fleabay £69.99 brand new genuine subaru part apparently and its a shop

 

av i ever told u i love u

 

i've got a good used one for £22 shipped

 

I paid about £25 for a new one for a MY99 from a dealer

 

there a little more exspensive for the old imports

 

pm sent

 

I got a new one from AmericaRockAuto Parts Catalog
Just put the part number in the search it was only $40 + shipping but will have to wait about a week for it.

 

yeah whenever i give you a reach around

 

You probably do not need a new sensor.
Have your ECU read, then reset the ECU and clear the faults.
After thay, keep an eye on the check engine light but chances are it is OK.
If faults reoccur then take it from there but any CEL activity should be investigated promptly.
