sonique 0 Posted March 9, 2006 Can anyone with a 9a engine confirm if you have this sensor fitted it's #4 in the attached picture. I was looking at mine and there is no sign of it and no wiring for it. Why would it not be fitted? Quote Share this post Link to post Share on other sites
bcstudent 0 Posted March 9, 2006 I'm sure it was there on my friend's 9A engine. I don't have the car here anymore though so I can't say for definite. There'll definitely be one on that end of the cylinder head somewhere as it controls the 'on' time of the cold start valve. Quote Share this post Link to post Share on other sites
