What this block covers
Fuel and air metering
The engine measures the incoming air and meters the fuel so the mixture is right; the throttle, the accelerator pedal and the turbo are here too. A fault usually shows as higher fuel use, jerking, lack of power or hard starting.
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.
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.
