Engine Code (P0506)

Thru this code last night, had it checked today. Code description was "The PCM determined that the engine RPM is lower than expected for the current engine operating conditions.". I have discounted the neg. battery terminal to attempt at reset. Has anybody ever seen this code before.

Truck has 51,000m ans NO mods.

I have it too. I think cleaning the throttle body out fixes it.

I just did mine. Had the light for p506 over a month and it finally warmed up enough to do it. Intake side looked ok...other side had a good amt of carbon build-up. Grabbed my chem gloves, some cleaner and sprayed/wiped away. Oiled the ends of the butterfly valve, and re-installed. Also picked up some MAF cleaner. Cleaned the K&N too. Put it all back together and BAM, no Check engine light and idle is up from 550 to 650. Loving life again. Its funny that the dealership always said my rough idle was normal....stupid mother fuckers!

GET IT DIRTY!!!!!
