Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

Basic error definition

Mass Air Flow Sensor 1 Circuit Low

Cause of DTC

The Mass Air Flow (MAF) Sensor and the Intake Air Temperature (IAT) Sensor are combined into one component. The Powertrain Control Module (PCM) provides a common 5-Volt Supply and sensor ground that is shared by both sensors. Each of these sensors sends feedback to the PCM on it #39;s own signal circuit. The MAF Sensor is a transducer that varies resistance according to changes in altitude and atmospheric conditions. With the ignition on and the engine not running, the MAF Sensor provides the PCM with the Barometric Pressure reading. When the engine is running, the MAF Sensor signal supplies the PCM with the current air pressure within the Intake Manifold. The IAT Sensor signal supplies the PCM with the temperature of the air entering the Intake Manifold. This information is used by the PCM, along with other inputs to calculate fuel delivery, and timing needs.
