i have a P1400-EGRC solenoid valve
and P0440- small EVAP leak

everytime i clear them they keep coming back, anywho what's the best way to get them fixed.

Btw, my gas tank lid doesnt close on the hinge perfectly if that makes a difference with EVAP? like i have to push it in when im closing it and i have to pull it out with like a coin or key to open it and fill gas for example...

Oh and my gas mileage is like 9-10 MPG on premium =/

all suggestions would be great ! thanks

 

I don't know about the codes but I do know the lid will NOT make a difference AS LONG AS your cap is fully secured! My lid doesn't close fully either what's important is the cap. Good luck

 

oh alright thanks
yes its very old, ill be swapping it tonight
=]

 

what about the other problems, does anyone know anything about them lol

 

you need to change the EGRC solenoid valve. Its next to the engine on the side the airbox is on. There is a brown connector and a black connector and a green connector. One of them is it, but I cant remember which is it.

 

ok i see,thanks i just found it online for like 25$ no problem ill be changing this then. but hmm, what does it actually affect?

what about the evap problem, i think that i have to change a fuel filter, but im not sure =/
what do u think

 

The P0440 is for a small Evap leak. Your fuel filter is not part of the evaporative emissions. My first check would most definately be a gas cap. Check to see if its tight. If it is tight, and the light stays on, you have a faulty gas cap.

 

oh snap!
im changing the gas cap first thing 2mm morning. thanks guys ill let u know what happens asap! =]

 

can an o2 sensor be bad but not throw a code ? because im really suffering from filling the car with premium gas and getting about 9/12 city/highway mpgs >.<

 

Egr solenoid valve is P1400 and thats the green plug on the right of the middle of the engine if your standing and facing the engine.

 

The leak is likely a bad hose. Check the vacuum hoses in the evap system. motor, valve, tank, and charcoal canister. I'm at wotk now or I would post a diagram for you. If the cap is tight and has a good looking oring/gasket it likey NOT the cap.

 

ok i see
i changed the cap anyways but still the same problem, and yes i just bought an egr solenoid valve online, and hopefully this will solve that problem

now the leak, i did check vacuum hoses but i dont see anything near evap system or motor or charcoal canister so idk =/ what else could be at fault?

 

Take it to a shop for a smoke test, locate the leak, take home and fix it your self. If they dont have the equipment take it somewhere else. Without smoke, a shop cold mess around all day and not find it.

 

will do !
thanks

 

just swapped out my egrc valve solenoid, did a ecu reset with a scanner and no more cel light.

i was able to get to the 10mm nut out with a stubby ratchet type wrench (no flex)

getting the hoses out was a little harder. i used a door remover tool to get the hoses loose and slowly twisted as i pulled. (btw, this tool works wonders when changing the fuel filter)

when it was time to get the nut back on, i used some tape to temporarily attach the nut to my middle finger to get it positioned right.

very quick fix. i have no more cel. and immediately noticed more power and smoother shifts.

i've been getting 230-250miles a tank (usually fill 14-15 gallons) of sunoco 93 octane. i'll update my mpg after a couple of tanks.

 

Wait, what door remover tool?

Like this tool?

 

yes, exactly like that one. almost the same price at auto zone

 

alright ill be working on this first then. ill keep everyone updated

 

Just a couple points on your mileage, which no-one addressed. If you live in NYC and do a lot of city stop and go, you'll get poor mileage. Still shouldn't be that bad. If your tires are under inflated you'll lose 1-2 mpg, s/b 31 psi or so. Quick take-off and holding gas on too long also loses 1-2 mpg. you can let off about a block early and still not go too slow. I drive mostly inside Halifax, and rarely get over 35 mph, and and rarely more than 2-3 blocks at a time - I get about 17-20mpg. Highway I get about 25mpg. of course, out here in Nova Scotia they don't sell over 91 octane ( if you can believe the dealers) - I usually toss in a can of octane booster. Also make sure you change your air filter in spring and fall - 6 months of pollution can block a lot of airflow.
