Question no boost

Hi

Yet another code(s) for my truck.

I am showing p1247 , p1248 and p603. The 603 doesn't concern me at the moment but the other two are very apparent when driving.

I have checked all the boots and none seem to be leaking. Maybe a possible MAP sensor?
Any suggestions ?

Re: no boost

It could very possibly be the MAP sensor. Do you have a scan tool that will monitor it? Did you ever unplug it with the key on?

Hi

I haven't disturbed it yet. On a gamble, I ordered a new one several days ago and it should be here today .

Re: no boost **fixed**

Hi

I installed the new MAP sensor last night and today, I can hear the turbo whistle and what difference in performance.

Thanks for the help.
