hi looking for help
engine check light comes on when car up to temp it goes off anyone with advice for me
thanks clive

 

You can check for error codes here www.JollyGreenMonster.com - Engine management specialist on the help page (only if it's a classic shaped impreza though)

 

right done a check it come up as 22 knock sensor any ideas how to cure fault

 

anyone got detailed advice on fiitting a knock sensor

 

Remove intercooler and and blow off valve,look on the left hand of the block(the cars left not yours) you will see and round sensor bolted down with one 12mm through the sensor,use a snap on shallow magnetic socket on a 12'' extension to remove the bolt undo the small white multi plug to the sensor and pull out the sensor,clean the engine block where the sensor bolts down(important as the sensor earths to the block) set your new sensor over the bolt hole,lube the bolt and gently wind it in to 15nm any more will damage the sensor,connect multi plug and re install all the componets,clear the memory and done...easy

 

Mine had the same error code when I got the sensor off it had a split in the casing.
I ordered one from the US saved a fortune. About $65 just over £30 with the postage. Dealer in UK wanted about £120.

Should be here Monday so hopefully all running again then
