P0104 - MASS OR VOLUME AIR FLOW A CIRCUIT INTERMITTENT/ERRATIC
| Description: | A fault exists in the mass air flow (MAF) A circuit, or the air tube containing the sensor, causing an incorrect air flow reading. | ||
| Possible Causes: | Intermittent circuit A open or short. Air leaks in the tube from the MAF sensor to the throttle body. | ||
| Diagnostic Aids: | VERIFY the integrity of the Mass Air Flow Sensor circuit A, for intermittent fault. CHECK the Mass Air Flow Sensor tube for air leaks. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
