How to Fix P1102 MERCURY Code?

Start by checking the “possible causes” listed above. Visually inspect the corresponding cable harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

When is the Code Detected?

The Engine Control Module (ECM) detected a mass air flow sensor (MAF) signal below the calibrated limit

Possible Symptoms

P1102 MERCURY Meaning

The 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 engine startup, the air flow voltage signal is above 0.27 volts, the test fails. Similarly, if while the engine is running, an air flow voltage signal is not between 0.46 volts and 2.44 volts, the test fails.

P1103 Meaning

The Manifold Absolute Pressure (MAP) sensor provides instant manifold pressure information to the engine’s Engine Control Module (ECM). This data is used to calculate air density and determine the engine’s mass air flow, which in turn determines the required fuel delivery for optimal combustion. A fuel-injected engine may also use a Mass Air Flow (MAF) sensor to detect intake air flow. A typical configuration uses either one or the other, but rarely both. The MAP/BARO Switch solenoid switches the air flow passage based on the voltage signal sent by the ECM.
