By a cheap OBD2 (95 or newer) scanner (Kragen auto) and retrieve the fault code(s), if it is a 1995 or newer many of the basic codes are common to all cars, reference this code to a repair manual at your local libary or go on line and type in the fault code, many times an explation and common parts that fail to set the code will be posted, remember the code tells what system is at fault, it can be wiring or a hard part like an O2/Cat sensor or the power train control module to name a few.

Toyota echo check engine gas cap

In my wife's case it was that the neck of the filler (where it contacts the gas cap) rusted. It didn't allow a good seal. Since it was a 2005 we also replaced the gas cap in 2013.

Fuel filler neck

Clean off the rust

The Check Light doesn't mean the
filler neck is the issue, unless you got
a code for a small Evap Leak & then
it could be any of 10 things & maybe
a bad gas cap

2007 subaru forester: why is check engine light on?

The CEL and Cruise blinking is the error indication. Could be any of several issues.
1. The gas cap is loose, or leaking. This is a VERY common error and is written up in the owners manual. The fuel filler neck could have a leak or rust hole.

2. A small exhaust leak on the "donut" gasket in front of the catalytic converter can cause a"cat inefficiency error", fixable by replacing the donut. For an '07, it unlike that the $200+ fuel/air O2 sensor or the cat needs replacing.

Check engine light comes on, will be on for couple days up to two weeks then goes off only to come on again after a while. code po420. I've replaced both o2 sensors and replaced the gas cap, the...

The after market cat is the likely problem. Catalytic converters are not all the same and over time our shop has learned which aftermarket ones will work and which ones will not.

The computer is looking at the downstream O2 sensor (the one after the cat) to determine cat efficiency. If the downstream O2 sensor is switching simular to the upstream O2 sensor (the one before the cat) than the computer interprets this as a bad cat. The rear O2 sensor should hold a steady voltage at idle once the car is warmed up.

Check engine light is on, on my 2002 honda accord ex v6

Could be as simple as a loose gas cap or cap seal or a bad o2 sensor. A falty cat. converter will also cause the check engine light to come on. Either way, you need to go either to a dealer or some auto parts stores will plug in the dioegnostic sensor and can tell what is wrong. your gas milage will suffer until you get this fixed. Your engine computer uses the inputs from your o2 sensers to adjust the fuel air mixture of the engine for optimum engine performance.

Missing flapper valve on an 06 town & country van's gas tank

I doubt if that is the reason your check engine light is on. It is more likely an o2 sensor. However make sure your cap is tight when you add gas and don't leave the engine running while the cap is off. That can trigger the light
