What does this mean?
OBD2 Code P0506 Alfa Romeo definition:
This P0506 Alfa Romeo code is one that’s sometimes triggered on vehicles that have electronic throttle control. That is, they don’t have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0506 Alfa Romeo DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is lower than the desired (pre-programmed) RPM.
Symptoms
