P0183

I am getting this diag code for the Fuel temperature Sensor High. (P0183)

I had a few questions as I look at diagrams. It looks like the fuel level is on the driver side and I know the pump is on the passenger side. Is the fuel temp with the sender on the driver side. I know some pics are universal but it looks like there is a level unit on both sides??

Some history on the problem:

On Thursday evening I did the deadly sweeping right turn with about 2.5 gallons of fuel. Car sputtered and died. I tried starting again and it would kind sputter and run rough. I pushed the car a block to my house and put in a gallon of fuel.

The car started up fine. I took it and filled it up. 14 gallons. (so I know there was some in there). I drove it before and after work and at lunch on Friday. And back and forth to work on Saturday. (I did my transmission service, drain and fill). (I work at a Chevy Dealership).

Sunday morning when I got into the car is when I had the light on. Runs as normal. I clear it and it comes back after the next start up. I put 100 miles since the last fill up so I decided to fill it up again and see if it made a difference (4 gallons) Light still came on.

I was going to pull out the two units and check the condition of them and try to locate which side the temp sensor is on. I hope to just change that but I know Nissan probably sells it as a full unit. If anyone can save me some time or had this issue on which side needs to be replaced. Thank you!

Download the FSM. It should be able to answer your questions. Link in my sig.

The temp sensor is integrated with the fuel level sensor. One of the members that's doing an LS swap posted a picture showing the temp sensor and the fuel level sensor wiper contacts.

Perfect. FSM was pretty similar to what I found in prodemand.

Is there a part number for just the sensor? It looks like Nissan only sells it with the whole assembly.

I have seen them sell the fuel level sensor and temp sensor on ebay/ parts store. Has anyone ran these? Not sure if it is worth risking dropping 100 buck on one if I end up having to get the whole thing. Luckily it pretty simple to get out.

A quick search through rock auto and a couple other websites shows that the fuel temp sensor & fuel level sensor are part of the same assembly.

This appears to be the best price. Hope this helps.

Did you do the voltage/resistance checks as shown in the FSM?
This will verify sensor issue or wire/harness/connection issue.

The type of temp sensor used (NTC thermistor) is VERY durable and generally don't fail.

If the fuel temp circuit is open (as in broken wire/loose connection) it will set a P0183 "An excessively high voltage from the sensor is sent to ECM" due to the voltage divider circuit on the ECU circuit board.

The link above shows the wrong part and does not have a fuel temp sensor. Just 2 wires for the variable resistor to indicate the fuel level.
The fuel temp sensor is *ONLY* on the fuel pump assembly as show below.

Thanks for the pic, Sonic. I was just doing a quick 'hunt & peck' type of search.

No worries

The only reason I know where the fuel temp sensor is from picking up a complete fuel system (fuel pump, rail, injectors and manifolds) at the scrap yard last year for research.

Find a member with a spare or dead fuel pump module and buy at pennies on the dollar to swap sensors.
