Top 10 2005 Nissan Frontier Questions & Answers

P0455 is a evap gross leak. your vent control valve is stuck open you will need new vent valve and a water separator kit to resolve the P0455/evap gross leak.

The problem with your truck is not the fuel pump. Its the sending unit for the pump, which is on top of the fuel tank and feeds POWER to the fuel pump. Nissan has a campaign for it, because those units corrode internaly inside of the connector, that sends power to the fuel pump to power it up. Have the dealer run DCS check , to see if you have a open campaign for the sending unit. If you do, it will be free of charge and in some cases the whole fuel tank needs to be replaced also. However, that may not be your problem. I have seen ECM/computer getting flooded by the heater box. There is a drain tube, that drains your heater box, that tube gets clogged up by debriss/stuff and that's when water has no place to go and it leaks on top of you ECM/computer and fries it. Have you noticed any wetness on pass. side floor?? Right by the fire wall. Check it and make sure that its dry/carpet area at the top of the carpet behind the glove box. If its wet, that's not good. Let me know what you have found and will take it from there. Is the "Check engine light on" by chance?? Let me know.

Make sure you have 12 volts from the positive side of the battery to the starter. Check the small wire on the starter solenoid and make sure you have 12 volts when cranking engine. If voltage is correct, the starter is bad

Built in the gas tank. It is cleanable. Don't have to buy a new one.

It is built into the pump so if it would have to be replaced then you would have to replace the whole pump. To me thats pretty crappy design.

Crawl under the truck, you should have two or three lines coming off the fuel tank, one will have the filter, one is the return, and one is emissions.

Just because the code states it's a sensor, does not mean the actual part is defective. The code could be set off by something else in the circuit or wiring. I would have a good repair shop look at this before making any repairs or purchasing any parts.

A code P0430 may mean that one or more of the following has happened:

• The catalytic converter is no longer functioning properly
• An oxygen sensor is not reading (functioning) properly
• There is an exhaust leak

It is most likely that an O2 sensor just prior to the catalytic converter has gone "lazy" and is not reading properly. To remove the O2 sensor, I would soak the sensor first with a rust penetrant and then you will need a 7/8" wrench or socket (depending on the sensor's location).

any time two or more electircal gadgets die together a common item, such as a fuse, is to be checked. in your case seems the light circuit, excluding the headlights, has a fault. if the fuse blows again i would examine the wiring harness, especially to the rear lights, for damage and then each of the light sockets for dampness. if no fault is found, i would replace the light switch relay and then the switch itself.

it depends if it is a 4 or 6 cylender, if its a 4 cylender bank 2 would be the oxygen sensor closest to the converter. if its a v6 bank 2 is usually the passengers side.. is it bank 2 sensor 1, or?? they code them in a few different ways so its hard to explain... but on a 4 cylender bank 1 is cosest to the engine, and bank 2 is closest to the cadalatic converter..
