I'm getting this code approx once a week........scanner says it's a low input. At first I thought the MAP sensor was bad, so I replaced it. Still get the code. It's a little irritating, since the truck runs a little weak after it pops that code. Mods are in my sig, with the exception of a Quadzilla boost fooler, which I haven't added onto the sig. I added the boost fooler over a year ago and have had no issues, this is a recent development...started a few weeks ago. Could the fooler have failed?

It could very well be the source of your problem. Completely disconnect the quad and clear the code and see what happens.Altoona has some good fishin!

Most likely is your quad. I have seen a few edge boxes fail and throw the 0237. Remove the quad, clear the code and I bet it runs good. There is a guy on cf trying to fix these quad boxes now.

He's also here... Look up Yankneck696 he'll help you out.

Thanks all! Just to note, it's only a boost fooler unit, not a Quadzilla box. I'm leaning toward it being the problem as, other than gauges, it was the only recent change I've made to the truck.
