Hello everyone, i recently had my check engine light come on, got codes emc 100a (ecm internal fault, baro sensor faulty signal) and ecm 140a (map sensor faulty signal)

Where is the map sensor exactly on this car? I uploaded a picture of something I wasnt sure what it was and maybe that is it?

Car is getting increasingly worse gas mileage and surge at cold idle.

Thanks for any help

That's the camshaft position sensor in your picture. The MAP sensor is part #10 in this diagram. Follow the hose that connects to the intake manifold, I believe it's mounted ahead of the intake manifold but I'm not 100% sure.

Awesome thank you for the diagram and the identification of the camshaft sensor

I've been looking for couple days on a diagram but everyone I looked at was in a different spot I couldn't find.

I'm gonna go outside and see if it's there.

Found it, the vacuum hose was disconnected but sensor has no signal so I got to test the map connector and the map itself using a code reader

Thanks again for the diagram and response.

'04 V70, after changing oil and a dump and fill on the trans, CEL came on. Still runs OK with a slight hunting at idle. Oreillys read the code for me, P2227, MAP sensor. I bumped the hose off the manifold while filling/checking the trans. Thanks to bmdubya for the MAP sensor drawing!

Hey can someone tell me in that diagram what #14 is? I don’t think Iv never noticed that b4 on the left side
Of my engine? Also where does #17 go? It’s just randomly there on the print lol. And laaaaastly does anyone know if there MAP sensor the hose that come directly off the MAP sensor does that have a clamp? Or is it just there holding on by itself?
