P1101 Ford - Mass Air Flow Sensor Out of Self-Test Range

[wickedstangs]

Has anyone dealt with this fault code, during key ON engine OFF test? I replaced my MAF sensor and still have this code.

The air flow voltage signal is greater than 0.27 volts the test fails. Is there a way to lower this voltage?

no symptoms, I only drive the car once a year and its time for its Smog.. When I went to the smog place he put it on a code scanner and that P1101 popped up with KOEO test..

Possible causes:

- Faulty Mass Air Flow Sensor
- Air leak before or after sensor
- Mass Air Flow Sensor harness is open or shorted
- Mass Air Flow Sensor circuit poor electrical connection

I would check intake at the TB...

That was it a leak on the rear of the sensor.. Now I have a P1000 and need to clear with drive cycle.. thanks for the help..

right on bro!

For the drive cycle: let car idle for 1 min. then turn on AC full blast. Let idle another minute. Turn off AC. Let idle 1 more min. Turn off car. Open door, let overhead light come on, then close door.

For some reason this helps the computer "relearn" itself. If you did it correctly you will notice the RPMs fall down to the correct 800 RPM give or take a few. :beer:
