P1100 FORD F150 Possible Causes
- Faulty mass air flow sensor
- Air leak before or after the sensor
- Mass air flow sensor harness is open or shorted
- Poor electrical connection in the mass air flow sensor circuit
How to Fix P1100 FORD F150 Code?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
What Does It Mean?
The MAF sensor circuit is monitored by the PCM for a sudden change in voltage input (or air flow) via the comprehensive component monitor (CCM). If, during the last 40 key-on engine warm-up cycles, the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored.
When Is the Code Detected?
The engine control module (ECM) detected a mass air flow (MAF) sensor signal higher or lower than the calibrated limit
Possible Symptoms
Check engine light illuminated (or service engine soon warning light)
P1100 FORD F150 Meaning
The mass air flow (MAF) sensor circuit is monitored by the powertrain control module (PCM) for a sudden change in voltage input (or air flow) via the comprehensive component monitor (CCM). If, during the last 40 key-on engine warm-up cycles, the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) P1100 is stored.
