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???
How do you replace a fuel rail sensor?
Clean the fuel rail sensor harness with electrical cleaner to remove any debris. Step 8: Install the new fuel rail sensor onto the fuel rail. Screw in the mounting hardware finger tight. Tighten up the mounting hardware to 12 inch pounds then a 1/8 turn. This will secure the fuel rail sensor to the fuel rail.
What should the Octane be on a flex fuel sensor?
From dyno testing…the use of E85 will increase hp instead of removing. E85 octane is rated between 100-105 when gas is between 87-91 or 92 depending on what part of the country your from.. and running high octane doesnt mean squat if you dont need it.
How to change the fuel level sensor on your car?
How to Change a Fuel Level Sensor. 1 Step 1 – Close the Gas and Power Lines. Remove negative battery cable. Raise the rear hatch or open the trunk and take out the spare tire if you have 2 Step 2 – Detach the Tank. 3 Step 3 – Remove Transmitting Device. 4 Step 4 – Remove Fuel Level Sensor. 5 Step 5 – Fit New 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.
When to use the low voltage code p0178?
Code P0178 is set when the ECM detects a low voltage situation within the fuel composition sensor circuit. In most circumstances the presence of a P0178 or P0179 is a very good indication that the problem is electrical in nature. Code Severity & Symptoms The severity of this code is moderate.
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.
