P1102 MERCURY - Mass Air Flow Sensor In Range But Lower Than Expected
P1102 MERCURY Possible Causes
- Faulty Mass Air Flow Sensor
- Air leak before or after sensor
- Mass Air Flow Sensor harness is open or shorted
- Mass Air Flow Sensor circuit poor electrical connection
How is the P1102 MERCURY code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
What is the cost to diagnose the P1102 MERCURY code
Labor: 1.0The cost to diagnose the P1102 MERCURY code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?The Engine Control Module (ECM) detected a Mass Air Flow (MAF) sensor signal below calibrated limit
- Engine Light ON (or Service Engine Soon Warning Light)
P1102 MERCURY MeaningThe Mass Air Flow (MAF sensor circuit is monitored by the Powertrain Control Module (PCM) for an out of range air flow (or voltage) input. If during key ON engine OFF the air flow voltage signal is greater than 0.27 volts the test fails. Likewise, if during key ON engine running, an air flow voltage signal is not within 0.46 volt to 2.44 volts, the test fails.
