Gambit Posted September 9, 2014 Share Posted September 9, 2014 I think it's near the throttle body down at the side of it maybe need to take the Topmount off to see it, but I'm not 100% sure so hopefully Savage or tlag might be able to shine a bit more light on it for you :) Quote Link to comment Share on other sites More sharing options...
wrxweston Posted September 9, 2014 Author Share Posted September 9, 2014 Had a quick look couldn't spot it will take top mount off bit later and see cheers gambit 1 Quote Link to comment Share on other sites More sharing options...
Tlag Posted September 9, 2014 Share Posted September 9, 2014 Its bolted to the deck of the short motor. Gambit is thinking of the right area. It's almost directly under the idle control valve. You may see the wire/plug easier than the actual sensor. It's usually a single black wire with a white plug. You will definitely need to take the top mount off to change it. 1 Quote Link to comment Share on other sites More sharing options...
Tlag Posted September 9, 2014 Share Posted September 9, 2014 It goes just under the pale green dot: 1 Quote Link to comment Share on other sites More sharing options...
wrxweston Posted September 9, 2014 Author Share Posted September 9, 2014 Thanks tlag ! What sort of symptoms would this sensor being faulty be giving me ? 1 Quote Link to comment Share on other sites More sharing options...
Tlag Posted September 9, 2014 Share Posted September 9, 2014 Could be a number of things but usually just running rough. Sensor usually cracks and the crack opens when warm and closes when cold so until it's up to temp, everything can sometimes appear normal. Even when hot, the gap can close and give periods of normal running. 1 Quote Link to comment Share on other sites More sharing options...
