P0102 Trouble code

Mass Airflow (MAF) Circuit Low Voltage Input

  • The code P0102 code is often associated with P0100, P0101, P0103 or P0104 trouble codes as they are closely related.

  P0102 code means

P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the ECU (engine control unit)

 

The MAF Sensor has low voltage output problems which may have several causes.

  • The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly.
  • The most obvious problem is restricted airflow from the air cleaner to the MAF sensor which can be a clogged air filter.
  • The wiring or MAF sensor may be too close to higher voltage consumption components, especially alternators, ignition wires, etc. which can give false readings.
  • The MAF sensor can also be dirty or partially plugged with carbon causing a low reading. Many MAF units have screens and they can get clogged up easily, clean using a CRC 05110 spray cleaner.
  • MAF sensors must operate within specific ranges to send correct signals for the ECU to adjust correctly for proper engine operation and inputs from other sensors..

 symptoms of the P0102 code?

  • P0102 code will be normally preceded by the Check Engine Light coming on the dashboard display.
  • The engine can run near normal but it may run slightly erratically, have less power and idle inconsistently.
  • The vehicle may have too low of fuel consumption, which could cause internal engine problems.

How does a mechanic diagnose the P0102 code?

  • P0102 is diagnosed with an OBD- II scan tool. A qualified technician should then reset the OBD- II fault codes and road test the vehicle to see if the code returns. He can observe this by watching it live on his scanner while driving.
  • If the code does comes back, the mechanic will need to do a thorough visual inspection to determine any electrical connector, wiring, sensor, air cleaner, is plugged or damaged MAF unit.
  • If no problems are noted, then the next step is to have the mechanic do a circuit test with a millimeter that has a digital display to show sampling rate and sensor range readings to determine if the MAF sensor output is really too low or there is another cause.

how can fix the P0102 code?

  • Verify the code with a scanner. Reset the fault codes and perform a road test with normal driving.
  • If the P0102 code comes back, then it is important to follow the test procedure.
  • Inspect the electrical connector to the MAF to insure it is attached correctly. Disconnect it and then reinstall to insure fresh electrical connection to remove any corrosion on the contacts.
  • Thoroughly inspect for wiring being frayed, damaged, or broken on the connector. Repair or replace as necessary.
  • Check for vacuum leaks on the intake manifold hose and fittings, especially on older cars.
