SOURCE: 2003 Nissan Altima 2.5S, Check Engine Light Problem.

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

SOURCE: Gas smell when starting and small dripage when back up from under engine

It sounds like the return fuel line is leaking. There are two fuel line and one is the high pressure line which goes to the fuel pressure regulator then to the fuel rails. There is then a return line from the fuel rail to the gas tank.
With the amount of fuel leak, it's going to be the return line since it's not that bad compared to the high pressure side. Follow the fuel lines from the drivers side around the steering shaft to the engine. The high side and low side (return) run side by side and you should see it leaking when the engine is running.
Good luck and hope this helps.

SOURCE: Check engine light is on. EVAP small leak

You need to check the purge and vent solenoids for proper operation. You need to check the pressure sensor for out of range ( defective ). You need to check the filler neck for cracks and make sure the clamps are tight. You need to check the vapor lines for loose fit. I've seen at the charcoal cannister where the lines connect it may not be on strait. A smok test will reveal this if its not sealing. You may have a leaking rollover valve or fuel pump seal on top of the tank. You may just have a vacuum leak under the hood, These trucks have an Evap management valve also that can be leaking or out of specs. Look on the emmisions lable or vacuum chart under the hood. This will show you the underhood components.

SOURCE: Check Engine Light won't go off

If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!

SOURCE: 2003 Mitsubishi Montero (full-size) check engine

The engine is probably making a knocking sound because the oil needs to be changed or replaced. The check engine light is indicating that you will need regular dealership servicing soon, however you can still drive the vehicle but depending on mileage it will determine what services are required.

Why is my check engine light on

Be sure you did blow a head gasket!!. Check for antifreeze loss, or white milky stuff in the oil. Look under the oil fill cap and radiator cap for white greyish goo. That will be a blown gasket from over heating.

To reset the engine light, there should be a toggle switch located somewhere under the dash, just switch it to the other side and your done. it is a very tiny switch, so you may need to look pretty hard for it.

My 1999 montero sport has a check engine light that reads P0455 , what does that mean?

well LISACOXFLORE this code is to do with the emissions control ,,, (EGR) exhaust gas return or the MAP sensor (manifold absolute pressure sensor ) it should be a soft code meaning the it wont prevent the vehicle from driving, normally this is caused when the sensors needs to be changed or based on the type of fuel you use causes the cheak light to come on

Have po442 and po456. What does this mean? check engine light is on.

Hi, both codes mean: Evaporative Emission Control System Leak Detected (very small leak).
This may be a very tough issue to diagnose or it may be a simple problem like a loose gas cap. Check the gas cap, and visually check for any loose hoses under the hood and under the car.
Take care

I have a mitsubishi montero sport utility truck and my servic engine light came on, i noticed that it was leaking when i parked it, what do you think it can be?

As far as the engine service light, I'd go to Autozone and have them read the engine codes2_bing.gif. They'll do this for free at most autozone parts places. The codes will indicate what's wrong and you can then decide if you really need to fix it. As far as the leak, it all depends what is leaking and how quickly it leaks. Leaking a little engine or trans fluid is not a big deal. Leaking any brake fluid is always a big deal.

I have a 2003 montero sport leaking oil on the alternator. Is there any thing I could do to prevent this?

Find the oil leak and fix it
If coming from the timing case replace the gasket.
If from rocker remove it and replace the gasket
as if you have a oil leak then its fixable
1st check oil is it engine oil (black) or something else??????????

2003 montero sport. will not idle since battey boost

sit with foot on gas at steady 3000 rpm, then turn on all your lights, hazard warning lights, heater, and window defrost, if the power drops , then you need a new battery....sometimes the battery power can control the engine idle, the alternator is only for charging the battery, not for running the cars electrics, this is the battery's job
