Issues like high/low/intermittent voltages can set a “Circuit Malfunction” code on some applications. The causes of “Circuit Malfunction” codes are much the same as those for “Open Circuits” i.e., broken wiring, poor connections across electrical connectors or previously repaired wiring, loss of ground that prevents current flow, blown fuses, defective relays, faulty switches, or any of a host of other issues and problems that prevents a flow of current through wiring. This distinction between “circuit” and “sensor/component” is a great help to anyone trying to diagnose a circuit malfunction code, since it narrows the list of possible causes down considerably. With “Circuit Malfunction” codes, replacement of sensors and components in the affected circuit will almost never resolve the problem, since as the code suggests, the trouble is in the circuit. Note: “Circuit Malfunction” indicates that there is a malfunction in the control circuit, as opposed to a fault in a sensor or other component. The following Youtube video describes vane, analog or digital hot-wire, and vortex MAF sensors: There are a number of different MAF sensors including the most common – hot-wire sensors. Identifying the type of MAF sensor in your car will also aid diagnosis.

Please see the fuel trims article (P0171): When diagnosing MAF sensor codes, understanding fuel trims is very important. Troubleshooting will be the same for both codes. The difference between the two codes is the consistency of the malfunction in the MAF sensor circuit. This code is similar to P0104 – MAF sensor circuit intermittent.

The troublecode P0100 is set when the MAF sensor circuit is malfunctioning.
