Hello and thanks for your question. My name is XXXXX XXXXX I will do all I can to help.
Let me first ask, is this car turbo or non turbo?
ok, First of all, I would check all the turbo hoses, the plastic ones and the rubber one and from the intercooler. Make sure all the hoses do not have holes, and make sure the rubber isn't deteriorated and leaking. Your codes refer to an internal fault in the ECM. which is rare but I have replaced a couple of them before. If all the hoses look good, I would remove the ECM and inspect all the pins underneath for corrosion and remove and reinstall the ECM about 5 times to clean the connection on the bottom. If that did not fix it, I feel you will most likely have to replace the ECM itself.
Let me know if you have anymore questions.
Where is the ecm?
And the intercooler? I have no idea what I'm doing? This is my daughters car. I'm a nurse...have basic car knowledge that about it :-)
Alright I understand, the ECM is in a cover under the hood. However, you will need an ECM removal tool specifically for Volvo's in order to get it out.
The intercooler is a cooler for the turbo assembly. It is in the front of the car, There are large plastic air hoses that go to it.
Make sure those hoses are indeed on the inlet and outlet of the inercooler.
Because sometimes they can come off.
under turbo boost.
Is there anyway I can get to the ecm? I can't get the car to a dealer.
So how will I know if it is the ecm? If I get it out and do what you said and it still doesn't work? How much are these things they sound expensive.
Is there a way to diagnosis the ecm trouble for sure? The car was running fine until the battery died. It will crank and start for a few seconds...then it acts like its not getting gas. Would the computer just stop working like that? Is there a way to reset the computer? And how likely is it that the ecm is ruined. I have been looking on line and purchasing one is unreal.
I understand, With your codes it points that direction, Let me ask, when you try to crank it, do you get a "Start Prevented" try again message or an Immobiliser message by chance.? Also, what kind of scanner is this? I've seen some cheaper OBD II scanners give weird codes before.
I don't know what kind of reader it was. It was reading bout 1/4 tank of gas so I put more in it. It started and she was able to drive it. It was doing ok then it started missing again. She said it will set and idle now but when u try to drive it it dies. ???
We are not geting any messages.
Do u think the computer needs to be reset since we replaced the battery? some one told me to put the battery cables together? Will that blow something up? Or clear it long enough to get to a dealer.
