I currently have a check engine light which is giving me code P2228.

The technician that serviced my car said it was for the map sensor.

When I accelerate in my car there is no difference between roughly 70-75% throttle vs wide open throttle and the needle on my turbo gauge will not move past the 'o' in turbo under any circumstance. My car has 141k miles when this started happening.

Ive been searching the forums and I cant seem to find a picture of where the map sensor is located. I think I found it but it looks different than the part I purchased.

Welcome to SC..
P2228 is the fault code for the barometric sensor not the MAP..

Thats what I have figured out from googling the code myself. When I looked up both the barometric pressure sensor and map sensor online they appear to be the same sensors except one has a rubber O-ring.

Do you know where the Barometric Pressure sensor is located?

Did you replace the ECM/ECU? This can throw that code also.

 

[santiagoa526]

I recently had my ECU upgraded. It is possible i had the code before as I didnt check my codes before having my ecu tuned.

 

[Djfremen]

Who tuned it?

Brew City Boost. They are trying to help me with my issue but I thought I would also do a little research myself

the sensors are completely different.don't know why there showing them as the same...see link for location..http://www.saabcentral.com/forums/showpost.php?p=3975154&postcount=47

Thank you, I will order the correct part today after work

not all the 9-3 were fitted with the sensor,if everything was ok before the tune,then the tune has thrown up a glitch..give casey time to sort it out before doing anything yourself..

 

[santiagoa526]

Sounds fair enough, thanks

I was told I needed this part for my 9-3 2.0T ARC convertible, I have the same part and part number, but the sensor is so much different.

im having same problem...I bought the one with the O-Ring and it says it doesn't fit mine.

IIRC 2003 was the only year with an external barometric pressure sensor. The rest of them were internal to the T8 ecm.
