What does MAF code on Check Engine light mean?
MAF codes that light up the check engine light (CEL) on your instrument cluster. MAF sensor malfunction that DOES NOT light up the check engine light (CEL). Lean and/or Rich code (s). Fuel Trim code (s). A tremendous lack of power upon acceleration. Black smoke coming from the tail-pipe. Bad gas mileage. Vehicle may idle rough and stall.
How does MAF affect the current in an engine?
Whenever the temperature difference between the two sensing wires changes, the MAF will either increase or decrease the current to the heated wire. This equates to more air into the engine or less air into the engine.
What happens when a MAF sensor goes bad?
Whenever the temperature difference between the two sensing wires changes, the MAF will either increase or decrease the current to the heated wire. This equates to more air into the engine or less air into the engine. There are a number of driveability issues that arise from faulty MAF sensors. 1. Runs rich at idle or lean under load
What are the symptoms of mass air flow sensor malfunction?
This list covers the majority of symptoms I’ve seen with this type of Nissan mass air flow sensor: MAF codes that light up the check engine light (CEL) on your instrument cluster. MAF sensor malfunction that DOES NOT light up the check engine light (CEL). Lean and/or Rich code (s). Fuel Trim code (s). A tremendous lack of power upon acceleration.

Can a faulty PCM cause low fuel mileage?
Since the fuel pressure regulator is given specific air/fuel mixture directions from the PCM, it should always maintain the proper mixture. A faulty fuel pressure regulator can also be to blame for a sudden decrease in fuel mileage. These symptoms can also occur with a plugged fuel filter, failing fuel pump, or faulty PCM.
What should I do if I get an error code for MAF?
The most common repairs for this error code are as follows: Check all the electrical connector and wirings to the MAF sensor and make sure everything is attached to their designated ports. Then, disconnect and reconnect connector to refresh electrical connection of the MAF wiring harness. Repair any broken or frayed wirings on the connector.
What does error code p0100 mean on MAF sensor?
Because this error code affects the MAF sensor, it most definitely causes several drivability issues such as sluggishness and general decrease of power. That’s of course, aside from the triggered Check Engine light on the dashboard display.
