Uk Turbo 2000 Hesitation
Hi folks, got a 2000 plate uk turbo 2000 which is holding back threw boost, engine CEL is on flashing code 22 which I belive I knock sensor? Would this cause this issue? Thanks all

Yes 22 faulty knock sensor will cause issues
|
Thanks for the reply, feels like a pretty big power loss so hopefully changing knock sensor should fix the issue Then.
Another quick question, can my car be remapped, it has a Y7 ecu. Thanks |
Yes I do believe the post 1999 cars can be mapped. Check out the ecutek Site.
|
My knock sensor was causing big power issues too, replacing it and resetting the ECU made a huge difference.
|
Thanks for all the info guys! Where is the knock sensor located?? Thanks again!
|
It's a tricky one. If you have a top intercooler I'd imagine it's gotta come off first, I don't so I can access mine easily enough. You'll need a 12mm socket and some various extension bars to reach it. It's at the rear of the engine slightly right of centre down behind the intake manifold. On my V3/4 engine it's nearly directly below the idle air valve. There's plenty of threads on it and loads of photos on Google.

Cheers guys! When I plug in the 2 black connectors under the steering collum it shows the fault code, when I connect the 2 green connectors with the 2 black still connected to clear fault codes the engine light just keeps showing the fault code? Any idea why. Thanks
|
Have you replaced the sensor yet? If not, it'll just keep coming back I'd have thought.
|
Yes sensor is replaced just cant clear codes, thanks
|
When the 2 black and 2 green connectors are together I turn ignition on at check engine light is solid, soon as I start the car engine light goes off and it starts showing the fault code?

Yes followed procedure by driving car etc but it just keeps flashing the engine code

I'm sure you have this info and have followed it correctly but I have posted just too be sure. If it's still showing 22 knock sensor then perhaps it's the wiring that's faulty? You might have to get a mechanic(preferably Subaru specialist) to get it looked at. Unless anyone else has suggestions?
Ensure engine is at normal operating temperature, turn engine off Locate the two ECU connectors, located under the steering column and consist of a black plastic male and female connector, and a green male female connector With the ignition OFF connect black to black and green to green. Turn on ignition, do not start the engine, depress the accelerator pedal to full throttle, then return it to the half-throttle position and hold for a few seconds, and then release Engine Check lamp turns on Start engine and then drive for at least one minute, keeping road speed above 11 Km/h. ECU is now re-set. At this point the check engine light should start to flash the all clear signal (steady 1/2 second interval flashes). If the check engine light does not flash, or indicates some other sequence, there is a fault present in the system, and should be professionally checked for necessary repairs. Stop the car and turn off the engine. Disconnect the black and green connectors. Job complete |
Disconnect the battery and leave it off overnight, might do the job. Sounds like you haven't followed the reset procedure just right though.

Thanks for all help guys, cleared the code now car pulls how it should, thanks again guys
