What should I do if my car shows P0B24?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather).

If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
