|P1101 2001 FORD F150 code tech notes

The MAF sensor circuit is monitored by the 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.

|What is the cost to diagnose the P1101 2001 FORD F150 code?

The cost to diagnose the P1101 2001 FORD F150 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P1101 2001 FORD F150 code detected?

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

|What are P1101 2001 FORD F150 code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)

|What Does the P1101 2001 FORD F150 Code Mean?

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 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.
