What is the OBDII code for the Flex Fuel Sensor?
What is the OBDII code for the Flex Fuel Sensor?
This circuit is also referred to as the as the flex fuel sensor circuit and the OBDII codes that are triggered by the Engine Control Module (ECM) when this circuit malfunctions are P0176, P0177 and P0179. The fuel composition sensor circuit monitors the amount of ethanol in the gasoline on a flex fuel engine.
What does the fuel composition sensor ( FCS ) measure?
The fuel composition sensor (FCS), or flex fuel sensor (service parts term), measures the ethanol-gasoline ratio of the fuel being used in a flexible fuel vehicle.
What does the fuel composition sensor p0178 mean?
P0178 CHEVROLET Meaning. The fuel composition sensor (FCS), or flex fuel sensor (service parts term), measures the ethanol-gasoline ratio of the fuel being used in a flexible fuel vehicle.
Is the flex fuel sensor high volts or low volts?
P0178 – Fuel Composition Sensor. Sensor Circuit Low Volts P0179 – Fuel Composition Sensor. Sensor Circuit High Volts Can this really effect anything? Yes, It can cause your truck to run richer then it should. In my case I was also throwing an HO2 Sensor (P0141), this went away after I replaced the Flex Fuel sensor.
Where is the fuel composition sensor on my flex?

How to fix SES p0178-flex fuel sensor?
The new engine (2001) USED to be flex fuel. I used the old intake/fuel setup that was with my old engine (1999) After reading the description above… with the sensor that sits inline on the fuel line that reads fuels… can one get better gas mileage than the typical crappy gas mileage that using ethanol usually means with a regular fuel system???
What kind of fuel does a flex fuel vehicle use?
A flexible fueled vehicle (FFV) has a single fuel tank, fuel system, and engine. The vehicle is designed to run on unleaded gasoline and an alcohol fuel (usually ethanol) in any mixture. The engine and fuel system in a flex-fuel vehicle must be adapted slightly to run on alcohol fuels because they are corrosive.
How does the fuel composition sensor work on a car?
The amount of ethanol can very every time you fill up the tank requiring appropriate adjustments for optimal performance and fuel economy. The fuel composition sensor circuit sends a signal to the ECM based on the ethanol level. The ECM adjusts the ignition timing and fuel injector pulse width accordingly to burn the fuel more efficiently.
How to check and replace an oxygen sensor ( air )?
A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor. Nice O2 Sensor Socket Kit: http://www.amazon.com/gp/product/B005…
What does the fuel composition sensor code p0178 do?
The ECM adjusts the ignition timing and fuel injector pulse width accordingly to burn the fuel more efficiently. The end result is improved performance, reduced pollution and increased fuel economy. Code P0178 is set when the ECM detects a low voltage situation within the fuel composition sensor circuit.
