Hi Guys

(1.9TDI PD engine)

Hopefully you can help!

Recently had my check engine light come on with the code P0183 fuel temp sensor. I have changed the sensor and reset the light but the fault light comes back.

Have now tested the old sensor with a multimeter and it appears to work with the resistance changing during a temperature input.

Have checked other sensors on the engine with the ignition on,they are all getting a 5V supply.

However my fuel temp sensor is only getting a 2.5V supply but it is showing a good earth. So the wires not broken.

Any ideas on a next step. I'm stuck for ideas.

Should it actually be a 5V supply?
ECU fault?
Is there two fuel temp sensors?

Man many thanks in advance!!
