What are the symptoms of a bad mass airflow sensor?
These symptoms indicate a MAF that has a contaminated hot wire. The contamination can come in the form of spider webs, potting compound from the MAF sensor itself, dirt that gets attached to oil on the MAF from an over-oiled aftermarket air filter, and more.
What should I do if my MAF sensor is failing?
A MAF sensor that behaves like this will require replacement. Before replacing the sensor, however, the rest of the circuit should be checked for proper operation. If the circuit has an issue, replacing the sensor will not solve your problem. 3. Rough idle or stalls A completely failed MAF sensor will not send any airflow information to the PCM.
Which is MAF sensor does the PCM use?
The PCM uses this input to calculate engine load. There are several designs of MAF sensors, but the most common by far is the hot wire MAF sensor. The hot wire MAF has two sensing wires. One wire is heated and the other is not.
What does p0102 mean on a Dodge Ram?
P0102 is a very common trouble code with the Dodge Ram. It means the the Mass Air Flow (MAF) circuit is low, and that it is not performing within its specified operating range.

What does the code p0102 mean on a MAF sensor?
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. What the P0102 code means P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU).
What does a low MAF sensor mean on a Dodge Ram?
Dodge Ram P0102: MAF Sensor – Circuit Low November 26, 2018by Jason P0102 is a very common trouble code with the Dodge Ram. It means the the Mass Air Flow (MAF) circuit is low, and that it is not performing within its specified operating range.
What to do if your p0102 is thrown?
Without knowing how much air is really getting into the engine, P0102 will be thrown. MAF Sensor Wiring – Make sure to check around the MAF sensor for opens or shorts. Start by inspecting the wiring harness for obvious damage. If you don’t see any you can use a multimeter to test the wiring.
