So i bought this volvo a week ago. Its very clean. Almost new like.
Well i got a running issue.
Its 2004 volvo s80
2.9l non turbo.
Runs ok when cold. 30 seconds after starting it it has no power. Wont rev above 2500.
Wont go above 30mph
Codes coming up are
O2 sensro bank one sensor 2
Map/baro sensor
Brake sensor

So first can an o2 sensor make is run bad
And 2nd where is the map sensor for this vehicle.
Ive searched all over the internet and all over the car and cant find one.
Is it built into another sensor. And could the map sensor cause the car to not have any power.

I am very good with cars but this volvo has me stumped. I really would appreciate some help here on fixing this.

 

Sorry the o2 sensor is bank 2 sensor 1

 

The video link below should help you find your MAP sensor.

 

I dont have that sensor on my 04 volvo s80 non turbo.
Either some took mine out for some reason or it is located in a different spot.
Does anyone know if the mass air flow sensor acts as a map sensor also.

 

sorry. that was for a 2006.
A 2004 is a Mk1 (P2)
googling seems to come up with pics showing in contradicting locations.
It is confusing.

 

Yeah i know. Ive been looking for days. And ive looked at every spot online says and i dont have one. The only spot i havnt looked was one site shows a diagram of a part on top of the gas tank. I have taken the intake off and there is no place on it for a map sensor. And my intake only has 3 vacuum lines coming off of it. None going to anything looking like a map sensor.
So it brings me to either the mass air flow sensor does the job of the map.
2. The map is the one on top of the fuel tank.
3. Someone has removed it and all the lines to it.
I wouldnt think thats it but you never know.

 

MAP = manifold absolute pressure.

MAF = mass air flow.

 

Yeah i know thats what they stand for. I was just throwing out things i read online. I mean i have a map sensor code and there is no map sensor. So i was saying maybe ots built into another sensor. Idk i just really need to find something. Im dripping the fuel tank today to see if i see one on top of it.

 

The only sensor on top of the fuel tank would be evap related - should not cause a runability issue

 

I found another parts site that had diagrams of the fuel tank with a map sensor right on top. So if its not there where the heck is it. Ive pulled the intake off its not there. Ive followed all the vacuum lines off that come from the manifold and none of them lead to anything looking like a map sensor. Ive never had an issue like this locating a sensor.

 

Checked top of gas tank. No map sensor there.
I took the whole intake off. No mao sensor
Took whole air box assy out. No sensor there.
I fixed the o2 sensor code. Now its reading 420 and 430 code for a bad cat. Could i have 2 bad cats. Or just one. And y didnt it read them bad before.

 

I think I read that on the NA engines the MAP info can be read through the OBII port. That would at least verify it's presence.
