I have a 2002 S60 2.4T w 105k (haven't replaced timing belt etc.... yet).

My car started acting up and had trouble starting (check engine light came on). It idle rough for a while and giving a little gas also seemed like it was misfiring.

I used a generic ODBII scanner and it read the following: P0236/P0235. Could this be the issue starting the vehicle? I cleared the code, and it ran fine for a while, but it finally came back and started having issues again when starting.

I thought my trouble would be the throttle body being dirty (have not looked at it).

Any suggestions (Based on a similar thread it suggests the MAP sensor)?

Thanks in advance......

Thanks blackbrick,

Could that cause start up issues based on the turbo sensor?

 

I believe so but I am not expert. Wait for experts opinion.
Also do that timing belt ASAP

 

MAP sensor - its on the charged air pipe coming out of the intercooler (right behind it actually) open your hood and it will stare you in the face!

90 dollars or so at the dealer and literally a 90 second swap out.
