The check engine light also monitors the deairate system of the gas tank. On the undercarriage (below the drivers seat) are 2 rubber tubes which get briddle over time check those for cracks. If you don't find any it is probably necessarry to empty the gas tank complety, make sure the engine is cold and pressurize the whole fuel system with smoke in order to find that leak.

A blinking air bag light might indicate a broken insulation on one of the wires of the wire harness wrapped around the steering column(inside a black plastic cover). To access it it would be necessarry to remove the steering wheel.

Is E85 safe to use in the 2002 Dodge Grand Caravan Sport?


If your vehicle is equipped with a Flex-Fuel engine it is safe to use E85. If your vehicle is not equipped with a Flex Fuel engine, E85 will cause all kinds of driveability problems including a no-start. The vehicle should say "Flex-Fuel" on it or there will be a green "Leaf" emblem somewhere on the body.
For a 2002 Dodge Caravan, the best way to positively identify the engine is to look at the VIN. The only engine code that is Flex-Fuel is engine code "G". The engine code is the 8th digit of the VIN. The 10th digit is the year of manufacture and should be a "2" on your vehicle. If there is ANY OTHER engine code, DO NOT put E85 in the tank.

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!

Trouble code po456 evap small leak ? could it be the gas cap ?


Can't say 100% obviously, but quite often that is the cure, but try to take some time to make sure all your hoses , in the system are in good shape & tight.

Check engine light


you were told your vehicle has small/large evap leak detected? The leak could be coming from any number of components. Fuel tank seal, evap purge valve, check valve. The best way is to find the leak with a smoke machine. It is designed to find leaks in the evap system. There is a port with a green cap in the engine compartment. This is where the hose from the machine attaches to. Turn machine on. Where ever you see smoke, this is where the leak is.

2005 dodge grand caravan has check engine light code PO507


RE: Check Engine Light

The check engine light may come on for several reasons.

It is not necessary to worry as it may be as simple as putting the gas cap on without fully clicking it shut!. If this is the case it will go away by itself in about a week at most!
You can take your car to an auto parts store to have them run a diagnostic (Some will do this for free).
If your car is running fine, re-tighten the gas cap, give it a week or have it diagnosed if you still feel uncomfortable with it.
