How does the fuel temperature sensor work on a flex fuel vehicle?

How does the fuel temperature sensor work on a flex fuel vehicle?

Flex fuel vehicles function normally even if fuel composition levels are as high as eighty-five-percent ethanol. Fuel temperature is recognized by the PCM as pulse width or the horizontal portion of the waveform. The thicker the pulse width signal, the higher the temperature of the fuel passing through the fuel composition sensor.

What to do if your fuel temp sensor is damaged?

Damaged, burnt, or corroded wiring and connectors will need to be repaired or replaced. Next, clear the codes and retest the system. Utilize the OBD II readiness mode when multiple failure cycles are required for MIL illumination. Simply complete your repairs and clear the codes, then drive the vehicle normally.

Very interesting, A 05 Mazda tribute 3.0L listing a P0183 code (Fuel temp sensor circut). Upon research, this tribute has NO fuel temp sensor. The code may be set by intake temp sensor, there is NO intake temp sensor.

Where is the fuel composition sensor on a car?

The fuel composition sensor is computerized and is found in-line between the fuel tank and the fuel rail. As fuel passes through the fuel composition sensor, the percentage of ethanol, water, and other contaminants are assessed. Square waveform voltage patterns are input to the PCM according to the level of contamination in the fuel.
