I own a 2004 S60 2.5T, Vehicle has 66,000 miles on it. I decided to have the spark plugs and timing belt/tensioner/idler changed as a precaution due to other posts that I have read.


I recieved the car back, started and drove it 4-5 times before the CEL came on. Took the vehicle to Auto Zone for a quick code pull and the following codes were identified:

-P0193
-P0299

I have read that the P0193 is most likely the fuel rail pressure sensor, but
I am up to any suggestions
The P0299 code is what bothers me the most. Low boost pressure code. Any suggestions would be great in resolving my problem.

 

Make sure they did not knock any hoses loose while doing the work.

 

I do not get CEL but every now and then when I check for DTCs
I see P0299 (low boost). I guess it did not occur often enough to cause
CEL.

What hoses do I check ? ALL the ones connected to the TCV
seems to be fine.

Is this a sign that CBV might be failing ?

 

It is possible but I doubt it. I would also check the intercooler hoses.
