I have a 2005 Dodge Ram 3500, 600 series Cummins, and today after bringing my truck into the shop for a hour, I went to drive out, and the Check Engine light was on. Plugged in the code reader and get these 2 codes

P0236 Turbocharger Boost Pressure Sensor Performance / Rationality
P0238 Turbocharger Boost Pressure Sensor High

and 2 P/D of the same code.

Anyone have any insight for me? I have a Bully Dog outlook monitor on the truck and the rest is stock.

Thanks

 

Do you have the Outlook plugged into the MAP sensor for reading boost? If you do the connection or the Outlook is failing. If you don't then you just may need the sensor cleaned or the harness is damaged in some way. You can unscrew it from the manifold and try some sensor cleaner from the local parts store. I wouldn't use any other non-approved cleaner on it though.

 

Dammit, its back. I bumped the OBD pluggin on the bully dog when I was working under the dash last night. Go to work in the morning and the Check Engine Light is on.

Last time it went away, is it OK to do that again?
