Hi guys, have a problem with my Impreza MY95 Wrx.

On cold start the 'engine check' light comes on & the revs tend to bounce up & down. Once started & left running for 5 minutes light disapears & all back to normal!!?

Had it diagnosed and comes back as Fault code 41 Atmospheric Pressure Sensor Or Circuit??? where are these on the car?

Cheers guys

 

Anyone

 

MAP sensor.. little square sensor on the drivers side suspension turret..

has an electrical connection of 3wires and a small vacuum pipe connection.

It is black.. lol I might have a picture somewhere..

It is bolted to the manifold above the yellow powersteering cap..

TB on the front? Interesting

 

Here's a couple of pics of the MAP sensor in it's original location, tucked away in front of the off-side front suspension turret. It also looks as though it's mounted upside down.

This picture shows it top centre, with the vac pipe looping down to go up into it.


The second picture shows it bottom centre, with the silver label on it.


I would try and get a second hand one from a scrappy, because I seem to recall Subaru wanting £200 for a new one!

 

Cheers Dave,

Only trouble is i still can't notice the MAP sensor can you please place an arrow on the pic...Thanx a million
