Check Engine Light
Anybody know how I can obtain codes on a 99? I have a check engine light issue and it's done it twice in about 5 days. Would like to know what is going on before I go to the dealer. I know there are some threads on this, but I can't find them. Any help would be appreciated.

Autozone has code readers, they should pull them for free for ya.
I think with the 99, you are stuck using a code reader, no simple ignition sequence to read them.

Re:Check Engine Light
Thanks for the tip. Went to Advance, P0237. I don't know if that's MAP sensor or turbo boost sensor voltage too low. The reader said boost sensor, but the book of codes that I have says MAP sensor.
Anyone have a clue? Am I going to be stranded if I don't get this fixed like right away?

Re:Check Engine Light
According to my source, its
P0237 MAP Sensor Voltage Too Low
Might just try disconnecting, then reconnecting (will clean the connectors), maybe a little dialectric grease.
If that doesn't work, replacement might be needed.
Could be the Comp (Edge) messing up too though, not sending the right info, I think I've heard of that code in relation to Comp or EZ problems.
Might just disconnect the Comp if it gives you big problems, you'll have less power of course.
I don't think it will leave you stranded or anything.
Hope I'm right

Disconnected comp. Code went away and truck actually runs much better. Oh well. I can deal without the power for a while. Maybe I'll get a new comp later on down the road, or just replace it with an EZ and call it good. Thanks for the help

Re:Check Engine Light
Jack if you just want to know what the code numbers are turn the ignition on and then off 3 or 4 time in a row and that will show the code numbers. Maybe you already knew this but I thought I would mention it anyway.

I dont believe that method will work on a 99. At least it doesent on mine. Thats why i bought a code reader.
