P0176 Ford Description

Fuel Composition Sensors are used to determine the amount of ethanol alcohol in the gasoline. Normally, a gasoline engine should not have more than 10% ethanol alcohol in the fuel for proper operation. Some vehicles have a Flexible Fuel (FF) system on them that allow them to run on up to 85% ethanol alcohol in the fuel. The fuel composition sensor sends a frequency modulated signal to the engine controller which is proportional to the alcohol content of the fuel. The injector pulse width and the ignition timing are modified for the increased alcohol content. It takes almost twice the amount of alcohol compared to gasoline to produce the same power.

Note:

1. Need to look up additional OBD-II Trouble Codes(DTC), use the search box. Enter the 5 character trouble codes in the search box and submit the search. You can repeat the search as many times as you need, one diagnostic code per search.
2. Don't assume a particular OBDii code means the same for other automotive manufacturers as there are many manufacturer specific codes in use.
3. If your trouble codes are for a different automotive, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other manufactures. The search only looks at OBD codes valid for the currently selected manufacturer.
4. This code is for reference only.
5. Help us improve CarObdCode.com. Tell us fix the code. Any information is appreciated. Thanks.
