Code P1100 2002 Ford F150 Description

The P1100 diagnostic trouble code (DTC) for a 2002 Ford F150 indicates an intermittent issue with the Mass Air Flow (MAF) sensor. The MAF sensor is a critical component of the vehicle's engine management system, responsible for measuring the amount of air entering the engine. This information is essential for the engine control unit (ECU) to calculate the correct air-fuel mixture for combustion, ensuring optimal performance and fuel efficiency.

Tech Notes for P1100 2002 Ford F150

The MAF sensor circuit is monitored by the 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) is stored.

When is the Code Detected?

The Engine Control Module (ECM) detected a Mass Air Flow (MAF) sensor signal above or below calibrated limit
