So every day I start my truck, immediately, or within a few minutes the engine light lights up. I check and erase the following codes. Go on about my day. Codes do not reappear until the following morning.
P0069 Map-Barometric press Correction
P0237 Turbo Bost Sensor A Circuit Low
P0483 Cooling Fan Rationality Check Malfunction

Truck: ’06 CTD
Location: Arizona 40 deg + in the mornings, not really cold.
Mods: Currently I have everything off, although I had Quad boost fooler, bully dog, and I recently replaced the turbo, ’06 stock for ’06 stock swap.
Maybe I need to use dielectric grease at the turbo wire connection, and where the boost fooler pluged in???

Any Ideas?
