check engine

when I turn ob the ignition, a sign check engine appears in red
what does this mean?

if it is a steady check engine light it is not as bad as a flashing one. Check all fluids...connections...spark plugs...MAF...etc... Take it to an auto parts store like Ato Zone that will check it for free to see what codes are being thrown.

If you get a code refering to the fuel system or emissions, then retighten your gas cap. The light may not go away immediately, but will if that was the problem. It seems to be the most common cause of the check engine light coming on.

I can tell you my light has been on for over 50,000 miles! Isuzu shop cant find any thing wrong and resets it,...comes back on within a few mins,I also have a Amigo and Rodeo,both of them the check engine light is on,well...not the amigo any more, i disconected it when i was in the dash!.My Amigo has over 200,000 miles on it and the light came on @ about 25,000 not saying you should disconnect yours..,but i think you will find out this is a on going program with Isuzu!

alobar05 - There is a red Check Trans light but I do not have a red one for Check Engine - only orange, please post a picture.

Lashsquat - what is the code number? If the problem is still there, of course it will still be on.

Just found a great place to mount the ScanGauge code reader/reset and multifunction gauge - removed my storage bin where the CD player was and it fits perfectly!

Tone....Sorry for the delay on replying to you,had been out of town,
There is no code error ,it just reads no signal....?

What reads no signal? If the check engine light is on, there will be a code. If the reader says no signal, the reader is bad or imcompatible.

Tone,
What happened to the round multi function display and code reader/reset?

Still offering them but no takers - boost will be added later but manufacturer is too busy at the moment. Jay is running one installed at the top of the A pillar with a simple bracket and loves it!

Tone,
I'll probably be interested when they're able to display boost.Keep us posted.
(oops, sorry for the hi-jack)
