The P0102 code is the code for a problem with the Mass Airflow MAF Sensor.

P0102 Mass Or Volume Air Flow Circuit Low Input

3 to 240 depending on whether you clean the MAF first or replace it.

. Most auto repair shops charge between 75 and 150 per hour. It gives off a low voltage output to the Engine Control Unit. The Mass Air Flow MAF sensor is placed in the stream of the intake air.

When P0102 OBD2 error code is set it means that the powertrain control module ECM has detected a failure of the MAF sensor or its circuit. It is important to complete the entire diagnostic process when diagnosing the P0102 codeThis DTC can be. Engine-Codes - Mazda - P0102 MAZDA P0102 MAZDA Code - Mass Air Flow Circuit Low Input - Code Popularity.

Check for damaged components and look for broken bent pushed out or corroded connectors pins. The MAF sensor must be within the correct voltage range for the Engine Control Unit ECU to function correctly. Fault Codes P0100 Air Flow Sensor Circuit Malfunction P0101 Flow sensor signal output from the permissible range P0102 Air Flow Sensor Low Output Level P0103 High flow sensor output P0105 Air Pressure Sensor Fault P0106 Air.

The difference between the two codes is that the PCM has identified the sensor output as faulty for a P0102 code. Service engine soon light Poor idle. Code P0102 is set when your vehicles Engine Control Module ECM or Powertrain Control Module PCM detects a problem with the performance of your Mass Air Flow sensor MAF sensor.

The troublecode P0102 is set when the MAF sensor signal voltage or frequency is below expected values. It measures the intake flow rate by measuring a part of the entire intake flow. Check the Possible Causes listed above.

This is an important component of electronic fuel injected engines. This code is similar to P0100 MAF sensor circuit malfunction. Mass Air Flow Sensor harness is open or shorted Mass Air Flow Sensor circuit poor electrical connection How do I fix code P0102 code.

Your PCM and ECM use the MAF sensor. Hot-wire MAF sensors often become dirty causing a P0102 code. Since P0102 has to do with the Mass Airflow Sensor which is a huge part of the S10s engine combustion process metering it is going to cause noticeable symptoms.

Get this code fixed within the next month. P0102 Trouble Code Symptoms The most common symptom of P0102 is a Check Engine Light. Usually one or more of these symptoms will occur but its not uncommon to have no symptoms other than the check engine light.

Leakage of left air into the engine after the flow meter can also be a problem. The cost to diagnose the P0102 CHEVROLET code is 10 hour of labor. Since P0102 has to do with the Mass Airflow Sensor which is a huge part of the Silverados engine combustion process metering it is going to cause noticeable symptoms.

Your MAF sensor is mounted between the air filter and throttle body and measures the amount of air entering the engine. Usually one or more of these symptoms will occur but its not uncommon to have no symptoms other than the check engine light. The P0102 can often be seen together with the P0100 P0101 P0103 or P0104 trouble codes as they are closely related to the MAF sensor.

OBD-II Code P0102 is defined as a Mass or Volume Air Flow Circuit Low Input The Mass Airflow Sensor MAF measures the amount of air entering the engine and the Engine Control Module ECM uses the information to determine the proper amount of fuel quantity and ignition timing. This can happen for multiple reasons that include bad connections from previously required wiring corrosion in electrical connectors and improper installations of aftermarket components. If the input or output signal isnt right or its low for a specified amount of time this code will set.

Visually inspect the related wiring harness and connectors. Symptoms of the general failure code P0102 The Check Engine lamp lights up. Service engine soon light.

P0102 is a diagnostic trouble code for Mass Air Flow MAF sensor Circuit Low Voltage Input This means a problem with the MAF sensor. Code P0102 sets when the ECM detects a low voltage output from. The smoke coming out of the tailpipe is black.
