Mass Air Flow Sensor 01 02 Error

After cleaning my IACV and changing my plugs my check engine light came on and I recieved an error message of 01 02. I am not sure where the MAFS is and what to check to fix the problem. What do I need to do?

You probably forgot to plug one of the wires in. Check to see if they are any hanging wires. MAFS is the little black square thing on the left of the air filter. It's on top of a hose that go to the air filter.

I rechecked all the wires and now I notice my idle is at about 1500 RPMs. Does that have anything to do with me cleaning the IACV because I didn't touch the screw at the top. What's my next step???

try doing hte Maf ground mod/fix it might fix it



0102
Diagnostic Trouble Code 0102 points to a problem with the Mass Air Flow Sensor. The MAFS is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a thin film that is supplied with electric current from the Engine Control Module. The temperature of the hot film is controlled by the ECM a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to the hot film as air flow increases. This maintains the temperature of the hot film. The ECM detects the air flow by means of this current change.

This malfunction is detected when an out-of-range voltage is sent to the ECM. That voltage might be too high or too low.

a) An excessively high voltage from the MAFS is sent when the engine is not running.
b) An excessively high voltage from the MAFS is sent under light load driving conditions.

Possible causes include...
- Harness or connectors (the sensor circuit is open or shorted.)
- Faulty MAFS

c) An excessively low voltage from the MAFS is sent when the engine is not running.
d) An excessively low voltage from the MAFS is sent under heavy load driving conditions.

Possible causes include...
- Harness or connectors (the sensor circuit is open or shorted.)
- Intake air leaks
- Faulty MAFS

With DTC 0102 the ECM is supposed to switch into Fail Safe mode and limit engine speed to 2400 rpm.
