A malfunctioning or a dirty MAF sensor will not be able to properly judge and determine the airflow into the engine.
MASS OR VOLUME AIRFLOW A CIRCUIT LOW CODE
An engine that is facing a bad idle can mean several things but it is also a huge symptom of the error code P0102.Īnother one of the symptoms of having an error code P0102 is the fact that the engine doesn’t start easily. It can cause many car owners to think that there is something wrong with the engine. Rough IdleĪnother one of the common symptoms faced by car owners facing the problem P0102 is a rough idle. So a check engine light might be one of the symptoms that might indicate the error code P0102. The error code usually pops up when the mass airflow sensor has a low voltage output to the engine control unit.
Having a check engine light on can be absolutely nerve-racking and can cause a lot of stress to the owner of the car. The most common symptom of the P0102 error code has to do with the appearance of the check engine light. Here is a list of all the common systems that can help you diagnose the problem P0102. Not only does it result in poor performance from the engine, but it is extremely difficult to detect as well. The error code P0102 can be extremely problematic for an engine. This results in poor performance in the vehicle. The error code P0102 occurs when there is a breakdown in the communication between the MAF sensor and ECU. This process is then repeated every cycle. Once the information is collected from the sensors, the ECU passes this information to the car’s computer. This further communicates to the ECU the correct amount of airflow that allows the engine to work properly. The MAF and the oxygen sensors work closely in sync. The error code P0102 can be extremely problematic for an electronic fuel-injected engine. The engine control unit uses this information which further determines how much fuel needs to be sent to the engine. To put it in simpler or laymen’s terms, in vehicles with a fuel injection system, the mass airflow sensor determines the flow rate of air going into the engine from the intake valve. The error code P0102 usually pops up when the PCM determines that the signal is below specification for a certain amount of time. The MAF sensor generates a signal that is used by the power control module uses as a primary input for determining fuel control. The MAF sensor is usually placed between the air filter and the throttle body. The main responsibility of the mass airflow sensor is to measure the amount of air that enters the engine. An error code P0102 usually means “Mass Air Flow Circuit Low”.The code usually pops up when the ECU ( Engine Control Unit)/PCM ( Powertrain Control unit) senses a problem with the mass airflow sensor’s performance. The diagnostic trouble code P0102 is an error code that is not available in every vehicle’s library code. Conclusion P0102 Mass Or Volume Air Flow Circuit Low Input.A Diagnostic Trouble Code will not specify the part of the car that needs to be fixed or replaced. It can be a generic issue, manufacturing issue, or manufacturing issue.
MASS OR VOLUME AIRFLOW A CIRCUIT LOW SERIES
It can be one problem or a series of problems that might cause this code. Each combination of these codes relates to a different problem in the car. This five-digit diagnostic trouble code starts with a letter followed by four numbers (e.g. These codes are usually displayed on any OBD scanner when it is connected to the car’s system for diagnostics.
A diagnostic trouble code is a five-digit number that points out or identifies a part or parts of the car that may be malfunctioning or having problems. Mass Air Flow Sensor: A mass (air) flow sensor (MAF) measures the amount of air entering the engine to ensure proper combustion.The error code P0102 is classified or is a part of Diagnostic Trouble Codes (DTC). This can cause problems with engine performance and fuel efficiency.ĭecreased engine performance and acceleration.ĭirty or faulty mass airflow sensor (MAF)
