Anyone know what code p226b is. Truck threw that code tonight but smarty and our list doesn't say what it is

 

Its turbo related...


1st cousin to the p2262 and the new p2563 codes...

Not sure but I think its an excessive boost code. Probably sensor related.

 

"New DTC P226B - Turbocharger Boost Pressure Too High - Mechanical - indicates
incorrect airflow and can be caused by the turbocharger, which should be cleaned if
it is the cause for this DTC. This DTC can also be caused by other air handling
system components. Refer to DTC-Based Diagnostics to properly diagnose and
resolve this concern."

Stock guys can take it to the dealer and have them clean the turbo. For us modified guys, drive with the EB on and hope it cleans it up.

 

I was just going to delete this week! Is turbo clean free under warranty? Earlier this week I just had some throttle control valve issues. We shall see

 

If you are still stock and under 100k it should be covered.

Get it taken care of and then delete it.

 

The dealer will clean your turbo under warranty. I would get that code resolved before deleting being there is a slim chance that you may need your turbo replaced.

 

The exhaust brake still operates. So we shall see. Smarty will stay in wrapper one more week! Trucks got 90 k. Cutting it close

 

Id take it to the dealer and let them clean the turbo for ya. Get all that EGR crap out of there before you throw the Smarty on.

 

Well the **** dealer cleared code said all is well. I'm all paranoid haha.

 

Well, at least the code is gone.

 

I wouldnt be paranoid, just see if it comes back up, if it does make them FIX it.

 

No doubt you have a sooting up turbo and exhaust. Their is a new reflash for the PCM that should help. I did one yesterday. I posted the turbo
and exhaust cleaning bulletin on my site under the tips and info page.
