quick and dirty CEL test?

I have some oooolllldddd OBD2 software with a serial cable that I was wondering if it worked with my truck. I tried it this afternoon and was able to get a NO CODES response, and log MAP and RPM to the little digital gauges.

My question is, what is an easy and safe test that I can do to trip a CEL to see if it pulls the code correctly?

I tried unplugging the IAT sensor in the air box, but the dash light never came on, and the software didn't seem to notice either.

I am debating which way to go with my tuning and diagnostics modifications and code pulling is a big piece of the puzzle. If I already have that solved then

Pull the MAP sensor plug off and drive it. It will set the "Low Boost" code... Don't ask.......

Thanks!

Is that the two pin green plug, in the "spider" manifold in front of the turbo?

NO, it is going to your map sensor over the passenger valve cover. It has the rubber line going to it from the spider. It is your boost sensor.

I think I found it. It is hanging from a bracket, has the rubber vacuum line, and the electrical plug has a red slider piece.

Follow that rubber hose from the spider towards the passenger side -- it's right next to the cold-side I/C pipe on a bracket.

EDIT: Late as usual. Y'all got it...

Look at this pic. The hose just under my trans dip stick is the map hose going to the map sensor.

Thanks for the help guys.

I got it unplugged, started the engine and saw the light on the dash. I ran the software but still got the NO CODES response.

Would I have to drive like that for a bit to trigger an actual stored code?

If this doesn't work I'm going to have to decide between an Aeroforce Interceptor gauge or the AutoEnginuity software.

Our trucks are not OBDII compliant so there are not a lot of code readers that will pull the codes.

That's what I figured, even the almighty AE needs the Powerstroke add-on.

It was worth a shot but oh well.

Scan GuageII, Aero something from Terminator Engineering. Some of the after market tuners for our trucks, Superchips, Edge will read and clear the codes also. Best bet is an AE. Not only does it read codes but it does different tests also.
