Question about my obd codes.

I've had my 95 Discovery for about 4 months. I really like it. Anyway my obd is showing a 15 and I cannot seem to find out what this code is. Can anyone help me out?

15 Fuel Temperature Sensor

Engine fuel temperature sensor

The engine fuel temperature sensor is located in the
rail on the RH side of the ram housing. The sensor
sends fuel temperature data to the ECM, the ECM on
receiving the data will adjust the injector open time
accordingly to produce good hot starting in high

ambient temperatures.

Hope this helps.

The fuel temp sensor is on the fuel rail. A 19mm wrench will loosen it up. It takes seconds to remove and install another. Remember to disconnect the battery before doing any electrical work. If you need one, I have several good used ones in stock. New, from places like Atlantic British they cost $115. I have them on sale right now for $28 including shipping anywhere in the US with a 60 day warranty.

Locate and remove the old sensor before buying a new one.
It only works during hot starts, like after driving on a hot summer day, stopping for gas and then starting again.
If/when bad the engine can be hard to start when hot, but letting the engine cool down a few min can usually remedy this.
But if your thermostat is stuck open and your engine never gets fully warmed up it wont be a issue. ;)

I would check local junkyards first, it is located on the drivers side just infront of and under the throttle body.

Rite. I've never had an issue starting my truck. Just trying to remedy the code.
