How To Check Fault Codes

I keep reposting the fault code check so I though I would put a thread in to link to for everyone to refrence. The FAQ one is good but I like the video from YOUtube to show how it's done. Here are the links:

An this is what they mean:

12, 33, and 55 are normal and should happen every time you check the codes.

Thanks, Que. I've started giving that video also, especially to newbies.
Lately I've been researching and writing how to test various sensors with a multi-meter.
Mind if I add that to this thread when I get done with it?
Not to mention what you said about disconnecting sensors, and re-setting the ECU.

no start 95 wrangler 2.5 4cyl. cut off going down the road will not start bad its getting fuel just no spark replaced the coil twice and still no good. Checked everythings getting power but the tps, map sen 5v with key in on position. Codes 22,23,24 show up when I checked it. I know what they are but dunno why they would stop it from starting or getting spark they just control the fuel lean,rich part. Any ideas? Would greatly appreciate any.

Post up to a new thread. Yes they can stop you from running. You need to disconnect the battery for 10 seconds. Reconnect the battery, try to start it and rechec the codes. Post back in a new thread what you find.

Thanks Que! Can you also post the procedure for checking the PCM for codes with a trouble light for those of us with pre-CEL rigs? Maybe I'll be able to find it easier with the search function if it's in this thread.

The original video was a flash vid, I re-coded it into mp4 so now it should play on iPhones and Androids. Better quality than many other formats. I'll also up a vid about testing the IAC someday soon. BTW notice the youtube acct is owned by Oldtime Ironman. Here's to you, Que!
