P24D6
EVAP System Pressure Sensor or Switch B Circuit Range or Performance
Same as P24D5 with the signal in plausible range yet not matching the engine model. The evaporative system captures fuel vapor from the tank and purges it into intake; leaks or stuck purge valves leak hydrocarbons and cause emissions failures.
