P1101 MERCURY Code - Mass Air Flow Sensor Out of Self-Test Range
|P1101 MERCURY code 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 is the P1101 MERCURY code repair?
Start by checking 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.
|P1101 MERCURY code 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.
|What is the cost to diagnose the P1101 MERCURY code
The cost to diagnose the P1101 MERCURY 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 MERCURY code detected?
The Engine Control Module (ECM) detected a Mass Air Flow (MAF) sensor signal above or below calibrated limit
|What are P1101 MERCURY code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|What is P1101 MERCURY code 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 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.
