Code P0183

Hey 04EXPLORER,

The P0183 code relates to the Fuel Temperature Sensor A - Circuit High Input.

This can be potentially due to a faulty sensor or shorted/broken wiring.

The first stage would be to check the current temperature the sensor is reading.

Do you have access to a scan tool with live data?

Hey 04EXPLORER,

The first step is to work out whether or not you currently have a currently present fault or if it an intermittent fault. To do this you will need to access a scanner that can has this function. You can try deleting the code and seeing how long it takes it to return, that will give you a good idea of it is constant or sporadic.

The fuel temperature sensor on this vehicle looks like it is integrated into the fuel pressure sensor (on the fuel rail) I can get you the location and wiring diagrams for testing, but before doing this you will need to confirm you have an incorrect reading from the sensor.

Hey 04EXPLORER,

If you can find a way to get a read out from the fuel temperature sensor and give me the current value please. This would be very quick for someone with a scanner with live data.

The sensor in question is shown in the attached picture.

It states you need to remove part of the intake to replace the sensor but you may be able to unplug it without intake removal for testing.

If you can inspect and find the sensor, trace the wiring to see if there is any obvious damage. Areas where is can rub through or be pinched.

Let me know how you go locating the sensor and I can provide further diagrams if required.

Are you comfortable with wire testing?

Hey 04EXPLORER,

Awesome, please do let us know if this solves your issue.

Look forward to your response.
