Symptoms of a bad mass air flow sensor
As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.

P1095 Mass air flow ahead of throttle valve implausible (too high) Possible fault causes: - Hot-film mass air flow meter faulty (battered) - DME control module faulty (ambient pressure sensor at fault detection threshold)
P0103 - Mass or Volume Air Flow Circuit High Input
Possible causes- Dirty mass air flow sensor - Dirty mass air filter - Mass air flow sensor harness is open or shorted - Mass air flow sensor electrical circuit poor connection - Intake air leaks - Faulty mass air flow sensor
P0101 ISUZU - Mass Air Flow Circuit Performancehttp://engine-codes.com/p0101_isuzu.htmlForum CodePossible causes- Dirty mass air flow sensor - Dirty mass air filter - Mass air flow sensor harness is open or shorted - Mass air flow sensor electrical circuit poor connection - Intake air leaks - Faulty mass air flow sensor Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or 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
P0103 HYUNDAI - Mass or Volume Air Flow Circuit High InputPossible causes- Dirty mass air flow sensor - Dirty mass air filter - Mass air flow sensor harness is open or shorted - Mass air flow sensor electrical circuit poor connection - Intake air leaks - Faulty mass air flow sensor Tech notesBefore replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or 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. P0112 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Low InputPossible causes- Dirty air filter - Intake air temperature (IAT) sensor harness is open or shorted - Intake air temperature (IAT) sensor electrical circuit poor connection - Faulty intake air temperature sensor When is the code detected?An excessively low voltage from the sensor is sent to ECM.
P0068 Symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of power - Engine rough idle Possible causes - Large vacuum leak - Leaking air duct system - Mass Air Flow (MAF) poor electrcial connection - Manifold Absolute Pressure (MAP) poor electrcial connection - Faulty Mass Air Flow (MAF) sensor - Faulty Manifold Absolute Pressure (MAP) sensor - TP sensor not seated properly. - Faulty Throttle Position (TP) sensor. - Dirty throttle body When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
P0103 - Mass or volume air flow circuit high input.
Symptoms: Engine stalls, running rough, excessive fuel consumption, excessive smoke from the tail pipe, check engine light on.
Possible Causes: Dirty mass air flow sensor, dirty mass air filter, mass air flow sensor harness is open or shorted, mass air flow sensor electrical circuit poor connection, intake air leaks, faulty mass air flow sensor.
P0116 - Engine coolant temperature circuit range/performance.
Symptoms: Check engine light on.
Possible Causes: Low engine coolant level, ECT sensor harness open or shorted, ECT electrical circuit poor connection, faulty engine coolant temperature sensor (ECT), faulty engine coolant thermostat.
P0172 - Fuel Injection System Too Rich Bank 1
Symptoms- Engine Light ON (or Service Engine Soon Warning Light) - Excessive Fuel ConsumptionPossible causes- Intake air leaks - Front Heated oxygen sensor may be faulty - Injectors may be faulty - Exhaust gas leaks - Incorrect fuel pressure - Lack of fuel - Mass air flow sensor may be faulty - Incorrect PCV hose connecPossible solutionDirty air filter of faulty air flow sensor are common causes of the problem.
P0174 - Fuel Injection System Too Lean Bank 2
Symptoms- Engine Light ON (or Service Engine Soon Warning Light) - Excessive Fuel ConsumptionPossible causes- Intake air leaks - Front Heated oxygen sensor may be faulty - Injectors may be faulty - Exhaust gas leaks - Incorrect fuel pressure - Lack of fuel - Mass air flow sensor may be faulty - Incorrect PCV hose connectionPossible solutionDirty air filter of faulty air flow sensor are common causes of the problem.Bottom line possible defective Mass airflow sensor and or O2 sensor in cylinder bank number two.
