What does the p0101 code on the mass airflow sensor mean?
The powertrain control module (PCM) then uses that information to calculate how much fuel should be delivered to the engine. The P0101 code indicates that there is a problem with the mass airflow sensor or its circuit.
Why do I get p0101 on my VW?
One common engine code Volkswagen owners get is P0101. Whether it is a gas or diesel, the cause is the mass air flow (MAF) sensor, which measures the amount of air flowing into the engine. The sensor is likely overly sensitive.
What does ECM mean on Nissan p1217?
P1217 NISSAN Meaning. The Engine Control Module (ECM) controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant pressure, and air conditioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
What does the p1217 code on a thermostat mean?
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. What does this mean? The coolant system thermostat it’s the most likely cause of the P1217 code.
What does the p0101 code on the MAS mean?
What the P0101 code means. P0101 is the general code for a problem with the Mass Airflow Sensor (MAS) operating range and/or an engine performance issue.
What are the possible causes of p0101 Nissan?
P0101 NISSAN Possible Causes. Faulty Mass Air Flow (MAF) sensor. Intake air leaks. Dirty Mass Air Flow Sensor. Dirty air filter. Mass Air Flow sensor harness is open or shorted. Mass Air Flow sensor circuit poor electrical connection.
What causes the MAF sensor to throw p0101?
Intake Manifold/Vacuum Leak – If there is a leak in the intake manifold, it will be impossible for the MAF sensor to get an accurate reading. Without knowing how much air is really getting into the engine, P0101 will be thrown. MAF Sensor Wiring – Make sure to check around the MAF sensor for opens or shorts.
What does p0101 mean on a VW Beetle?
One common engine code Volkswagen owners get is P0101. Whether it is a gas or diesel, the cause is the mass air flow (MAF) sensor, which measures the amount of air flowing into the engine. The sensor is likely overly sensitive. If the sensor detects the flow is more than 18% out of spec, it will trigger the engine light.
