P1100 Code - Mass Air Flow Sensor Intermittent
Repair Importance Level: 3/3
Repair Difficulty Level: 2/3
|P1100 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 P1100 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.
|P1100 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 P1100 code
Labor: 1.0
The cost to diagnose the P1100 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 P1100 code detected?
The Engine Control Module (ECM) detected a Mass Air Flow (MAF) sensor signal above or below calibrated limit
|What are P1100 code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|What is P1100 code meaning?
The Mass Air Flow (
MAF) Sensor circuit is monitored by the Powertrain Control Module (
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) P1100 is stored.
