A dirty, or contaminated mass airflow sensor (MAF) can cause the engine to run poorly. The Check Engine Light may or may not illuminate. MAF sensor related fault codes P0102 and/or P0103 may be stored. In some cases, carefully cleaning the sensor element will fix the problem. If not, replacement of the sensor may be required.
