I bought a 1999 2500 extd cab 4x4 auto with 40k on it. (Stock) I have had a check engine light. I pulled the codes and came up with these:
P0236 Turbocharger Boost Pressure Sensor Performance / Rationality
P0238 Turbocharger Boost Pressure Sensor High
I am at a loss of where to start. Is this a MAP sensor problem? Wastegate?
