Question about 2007 Nissan Versa 1.8 Sl Hatchback

1 Answer


I went to Autozone to get the code of P2A00 what is it most likely out f the list : gas cap fuel pump, vaccum leak either the rear or front O2 sensors the car only has 45k. and it runs like a charm but seems lately that the gas mileage has gone down a little but I have been doing more in the city too.The performance is still good so could it be the O2 senors. I would like to reset this code and see if it comes back real soon or if it was a possible gas cap loose. Then what if the tire low light is still on even though the pressure is at the proper pressure?

The PA200 code is for a front A/F sensor, not an O2 sensor. This is a fairly accurate code and I am 99.99% sure that if you simply clear the code, it will come back. Is the car out of warranty?

The tire light will not go out on its own if the tire went really low. There are two codes the low tire pressure warning system can set and they are low tire and flat tire. The low tire code will go away once the pressure is corrected, the flat tire code has to be cleared with the computer at the dealership.

Just went to autozone to see what could be wrong with my car. So far, I see the gas cap was not placed on properly after pumping and the gas was probably topped off. Got these codes. p0420, p0441, p0446

PO420- Catalyst System Efficiency Below Threshold (Bank 1) More than likely a plugged converter or exhaust.Remove the upstream O2 (it'll set a code and be real loud) and then take it for a spin and see if power is restored.
vacuum switching valve may fix the PO441 code. Replacing the charcoal canister could be another thing also. Then your PO446 is EVAP emission control system incorrect purge flow. which could a gas cap, could be a fuel pump seal or pressure sensor, filler neck.

Siphoning gas

The fuel tanks have protective baffles in the fill stem and they block hoses from entering the tank.
There is an easy way to remove fuel. Two things you will need to do are Look up the fuel pump RELAY wiring in the Powerbox under the hood and buy a tire valve removal cap. Some tire stem caps made of metal have removal tools incorporated in the stem cap, inexpensive, Walmart or Kmart.
Why do you need a tire valve stem cap? To remove the stem valve in the fuel rail test port on the engine. Once this is removed you have an opening for fuel to come out. Remove the valve and slide a rubber hose over the stem and clamp it down. Around a 1/4 inch or 3/8 inch internal diameter hose, long enough to reach an empty gas can. Now you are ready to pump.
To pump, remove your fuel pump Relay. Look at your obtained diagrams of the Fuel pump relay Layout. Jump the 2 terminals. Maybe 27 and 34, Look for Yourself as Layouts differ. The fuel pump will pump when jumped.
I removed 17 gallons in about 15 Minutes with a blocked pump. Do this on a COLD engine. Outside, well ventilated. It works.
Suggest topics like-"Fuelpump Relay Bypass", "2000 Lincoln Town car Powerbox Layout". Or See Autozone Help section on Web after registering your car.
Tire stem caps will cost about $3 for 4 pack, fuel hose about $7 for enough. small clamp $?.

When the Fuel Cap is not attached, your fuel tank loses pressure and a sensor detects this. This causes your Check Engine Light to come alive. Replace the cap and wait for the code to disappear or go to Autozone and have them clear the code for you.

Had my check engine light checked at a autozone and came up with a u110c... Any ideas for this code?

Code u110c ( no fuel level) Remove the gas cap from the van. Reinstall and make sure to give the gas cap a full 5 to 6 turns. The code set in the system was set by the gas cap not being tightened enough or a faulty fuel cap. If it continues to reset code then replace fuel cap on van. Hope this will help.

2004 Pontiac Grand Prix, check gas cap

Could possible be the Fuel Tank Pressure Sensor. It is located on top of the fuel pump. The fuel pump access is located in the trunk, under the carpet, behind the back seat. The AutoZone part number is SU 1390.

I had check engine light and TRAC OFF. OBD-II MIL code was P1133 which is Air Fuel Ratio Sensor Response Malfunction and scanned by AutoZone. After disconnecting the battery for 10-15 minutes, the lights went off. I cleaned the gas cap and tightened it firmly. For the last 400 miles, the lights have not come back. When scanning using Snap-on one, no code was detected. I think gas cap was the reason for the lights.
