Engine light

Have over 107,000 miles and my engine light came on. My neighbor has a code reader so hopefully we can figure out whats wrong. Any ideas? This is the first time the light has come on. Just changed the oil and plugs.

Also a something i figured out with some newer vehicles, including kjs, if you dont have a reader you can turn your key on/off/on (or was it on/off/on/off/on) anyways it will show you the engine code on your odometer reading. from there you can ask around what it means, or google it to figure out what it correlates to.

Thats where my Dealer Service Manual comes in handy at :wink:

since you just did a tune up , check to make sure you did not knock anything loose, just an idea

i was able to pick up a haynes from auto zone. i have a similar code im hunting for on my jeep. i know there is at least one cracked hose i need to replace, just not positive if its loose enough or cracked enough to cause a leak, followed it best i could and only found one spot. i think theres also some places where they lead above the gas tank that are harder to see.

Could it be as simple as the gas cap?

could be, I have heard of people taking them off and then back on and its OK then

yes, if you didnt tighten it all the way, or if its not getting a tight seal. i think the computer pretty much reads for any loss of pressure in the system and throws codes based on that. im sure other people on here know about it in more detail than i do.

I took off the gas cap and put it back on. Will check under the hood and make sure nothing is loose.
