DTC P0102: Mass Airflow (MAF) Sensor Input Low: Condition

PCM monitors input signal of MAF sensor at terminal No. 88. If PCM input voltage is less than .24 volt, DTC is set. Causes may include the following:

• Faulty MAF sensor.
• Open or short to ground in Blue/White wire between MAF/IAT sensor harness connector terminal "E" and PCM harness connector terminal No. 88.
• Open in wire between main relay harness connector (Yellow wire) and MAF/IAT sensor harness connector terminal "B" (White/Red wire).
• Poor connection at MAF/IAT sensor connector or PCM connector.
• PCM malfunction.
