Code P0102 KIA Description

The Mass Air Flow (MAF) sensor is placed in the stream of the intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM). The ECM controls the temperature of the hot film by a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAF Sensor Signal is less than the factory specifications.

  • swapped engines. maf sensor bad. changed it. seems to idle ok,maybe a little rough.the longer it runs,the worse it runs. no power at all in gear. ???

  • Any other codes? did you use a new sensor? check the wires to the MAF, try wiggle the wires with the engine running, if there is a NEW MAF and still getting the code, it's possible that the problem is the wire.

  • kIA Jeep I scan it this is what I get how can I fix it P0102 the Kai is counsunfule
