What is this part and why does it matter?
The fuel temperature sensor measures the temperature of the fuel, which the ECU uses to fine-tune fuel injection calculations, since fuel density changes with temperature.
If you notice any of the following, the part likely needs replacement:
Check Engine light with a fuel temperature fault code
Slightly inaccurate fuel trim or minor performance fluctuations
Poor cold-start behaviour in some cases
Installation information
Screws or plugs into the fuel rail or tank with a seal, and connects to the engine wiring harness.
Frequently asked questions
Fuel expands and contracts with temperature, changing its density — the ECU uses this reading to fine-tune the exact amount of fuel injected for accurate combustion.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
