What this block covers
Transmission
The gearbox, especially automatic ones: its sensors, solenoids and torque converter. A fault may lock it in one gear (limp-home mode) or cause harsh shifts.
Engine (mechanical, cooling and lubrication)
The engine's mechanics, timing (camshaft and crankshaft), cooling and lubrication. Many of these codes check that the engine is in time and at the right temperature.
Speed, idle and auxiliary inputs
The vehicle speed sensors and idle control, the speed the engine turns at when you are not accelerating.
