Po463 po183 nissan versa

It's a 2008 nissan versa. 150k. I imagine this pump is original. Already replaced fuel pressure regulator. Are these two codes identical, or are they tripped by separate things?

Code p 0183 refers to fuel temperature sensor A --high input===causes --wiring short to positive ---fuel temp sensor--ECM
code p 0463 refers to fuel tank level sensor --high input===causes --wiring short to positive fuel tan level sensor ---ECM
if the temp sender and the fuel level sensor ( both located in the same fitting in the tank)are in the same wiring harness then there may be a connection as the wiring short to positive is common
check for the harness rubbed through somewhere causing the problem or an after market screw screwed into the harness some where

How do i fix my 2002 Altima that will not start?


Depends on the make but most likely i would say it is a bad connection, so i would check to see if the wires are possibly damaged. The two codes dont really relate problamatically.

If you have a volt meter you can check to see if the connections are grounded or damaged. I would start there. If you dont have a volt meter a cheap one is about 20$ and you can find on youtube how to use it.

Trying to find out how to check fuel relay in 2007 nissan versa


Had this problem last summer: car wouldn't start, though turned over, so I bought new battery. The problem turned out to be the fuel pressure regulator, which sits atop the fuel pump beneath your back seat. For a full (if bloody and funny) repair documentary, see http://www.youtube.com/watch?v=0FaJlkQlkTg.

How to change a 2005 nissan sentra fuel pressure regulator


If you want to replace the fuel pump regulator you are better off getting the whole fuel pump module I know its expensive.The problem is you went on line and there is a bunch of chatter about the fuel pump causing delayed starts. They are right. There is a TSB Nissan put out this includes the fuel pump and there is no mention of the regulator that I know of.

I know my fuel pressure regulator is not working properly where is the regulator located?


its inside of the fuel tank and is part of the fuel pump basket. remove rear seat (bottom) and you will see access hole. remove access hole cover and you will see top of the fuel tank. this is where specialty tool is needed to remove tha retaining ring for the sennding unit or you can use flat head screw driver and hammer and just go around the retainer as you are hammering to take the ring off. once you get it off, you can take it out of the fuel tank and replace regulator. its held in by snap ring. remove snap ring and remove regulator. reverse procedure to install.

My 2004 nissan sentra will not start, just turns over.obd code po455,po183 and po463 not sure what to check. I tried gas cap, took gas line off and turned car over but no fuel, it my be my fuel pump but...


P0183 = Fuel temperature sensor A circuit, high input

P0455 = evaporative emission (EVAP) control system leak detected (no purge flow or large leak)

P0463 = fuel level sensor circuit, high input.

Check to see if the charcoal (evap) canister is full of fuel. If so, empty it. Check for a faulty canister vent valve. Check for a short to ground in wiring to fuel temp sensor and fuel level sensor.

Nissan Almera 52 plate. not starting when it stalls.


One of the items you can try is to turn on the ignition switch, so the dash board lights come on, and wait 10 seconds before you start the engine. You have an electric fuel pump and it must build up pressure so you have the correct volume of fuel going to the fuel injectors. The fuel from the fuel pump goes to the fuel rail that supplies fuel to the fuel injectors. There is a pressure regulator to keep the fuel at the proper pressure. The excess fuel is then returned to the gas tank. On my 2003 Nissan Sentra SE-R SPEC V, I had similar problems. By waiting this amount of time I have ensured the pressure was up in the fuel delivery system and it was working as designed. I may have a bad check valve which then allows the gas to drain from the fuel rail, but I have not gotten this far yet in my own repair. This has allowed my car to start and not flood out, if it stalls as I had seen before. You may be experiencing the samething.

If your check engine light is on, you may have fouled spark plugs, check these out also, especially if you are seeing cylinder misfire in one or more cylinders.

Nissan versa gas treatment


I agree with Gary, it's not likely the regulator. More than likely it is the check valve in the fuel pump that doesn't hold the pressure after the car is shut off. Adding a treatment won't do anything but drain your wallet.
