I guys I've just brought a Subaru impreza turbo 2000 with 157k on the clock car drives fine and starts first turn of the key. Pulls really hard in all gears seems to be slurrry(spelling) when off boost but pulls like a missile on boost the heat shield is loose I it sound like a very high pitch tinny tattle like metal on metal.. Just recently it's started to show the check engine light thankfully I have a code reader built in and it showing code 22 apparently this is knock sensor the warning is never on for more than 3mins or so. The engine idles a bit lumpy when it's on but a blip of the throttle she levels out then purrs like a kitten.

Any ideas guys/girls.??

Possibly wiring to the sensor or sensor itself. I had a similar issue a couple years back.

Happend to my bug eye sport years ago..... Garage said been run on low grade petrol for too long( octain levels were low) they changed the sensor ect ran on v power there after, never came back on!! It might be that?

Was told by scooby clinic mine had gone and to drive car steady as it could detonate engine if driven hard. My advice is change it asap

Get a second hand one mate from a breakers. Easy enough to fit just have to remove intercooler. Personally I wouldn't risk not changing it mate

Very common problem, the knock sensors crack and break up causing them to fail. Very easy fix, just one bolt and pretty easy to get to.

what years that? lol us over here in N.Ireland never had the english reg prefixes!


yeah handy enough changed but CRITICAL that you DO NOT over torque the securing bolt! i also placed a small washer between bolt head and top of knock sensor

cause you'll crack the casing on the knock sensor and in turn end up with another busted knock sensor

its something like 19lbft
