P1102 - Mass Air Flow Sensor In Range But Lower Than Expected
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Ford RV Cutaway, 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Econoline.

P1102 - MASS AIR FLOW SENSOR IN RANGE BUT LOWER THAN EXPECTED
| Description: | The powertrain control module (PCM) monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If, during a key on engine running (KOER) self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a DTC is stored in continuous memory. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | Drive the vehicle and exercise the throttle and the TP sensor in all gears. A TP PID (TP V PID) less than 4.82% (0.24 volt) with a LOAD PID greater than 55%, or a TP PID (TP V PID) greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a concern is present. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
