P1100 FORD 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 do I fix code P1100 FORD?
Check 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.
Tech Notes
- Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
Cost of diagnosing the P1100 FORD code
The cost of diagnosing the P1100 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. 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 above or below calibrated limit
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1100 FORD Description
The Mass Air Flow (MAF) Sensor circuit is monitored by the Powertrain Control Module (PCM) for sudden voltage (or air flow) input change through the Comprehensive Component Monitor (CCM). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory Diagnostic Trouble Code (DTC) P1100 is stored.
