What does code P1211 mean?

Q: What does code P1211 mean?

Mass Air Flow Circuit Intermittent High. P1211 on Chrysler vehicles means the engine computer detected an intermittent high signal from the mass air flow (MAF) sensor circuit, where the sensor output voltage momentarily spikes above the expected range. The computer flags the fault when the high signal is not consistent enough to set a hard circuit code but occurs often enough to be stored as intermittent.
