P0104

Mass or Volume Air Flow "A" Circuit Intermittent

DTC P0104, sometimes indicated as P010400 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing mass or volume air flow "a" circuit intermittent.

The Mass Air Flow (MAF) sensor measures the amount of air flowing into the engine. The P0104 code means that the MAF sensor is reading too little air. This can be caused by a vacuum leak, a dirty MAF sensor, or a problem with the electrical connection to the MAF sensor.
To fix the problem, check for a vacuum leak, clean the MAF sensor, and make sure the electrical connection is good.

2006 FORD EXPEDITION with 41480.0 miles

My wife, three kids and myself were in our 2006 Ford Expedition limited coming down a mountain pass in lake tahoe when all of a sudden the engine stopped! A code on the dash read "fail safe engine mode". The steering wheel locked and there was no power, no acceleration. I was lucky to pull to the side of the road. The following day, i took the truck to the carson city, nv Ford dealer and paid for a diagnostic. Notes from dealer: road test could not verify. Performed eec self test, has code P0104. Performed wiggle test and pinpoint tests. Performed recorder-monitor test all the pids looked good. Removed the maf sensor. Has debris on the maf sensor wires. Recommend a new maf sensor." i put in a new maf sensor and air filter. In driving less than 3 miles after this was done, the truck did the same thing. The "fail safe engine mode" came on, loss of power and acceleration. I had to turn the truck off completely, remove key and restart. Then the truck did not hold the idle and died. After a second time, the truck restarted. I am still driving with the check engine light off and have another appointment with the Ford dealer tomorrow morning (6-24-10) to see what is going on. We are supposed to leave tomorrow and drive 1100 miles to return to denver.
