P05XX Codes – Vehicle Speed, Idle Control, And Auxiliary Inputs

Review all P05XX codes affecting vehicle speed regulation, idle control systems, and electronic throttle or cruise control malfunctions.

Table take note:

1) For DTCs P0540 – P0543 also see P2604 – P2609

2) For DTCs P0578 – P0581 also see P0564

a) The “A” camshaft shall be either the “intake,” “left,” or “front” camshaft. Left/Right and Front/Rear are determined as if viewed from the driver’s seating position. Bank 1 contains cylinder number one, Bank 2 is the opposite bank.

b) The “B” camshaft shall be either the “exhaust,” “right,” or “rear” camshaft. Left/Right and Front/Rear are determined as if viewed from the driver’s seating position. Bank 1 contains cylinder number one, Bank 2 is the opposite bank.
