TP Sensor DTC P1122
 

Is this a vacuum tube linked to the throttle position sensor? or something else? As you can tell, it is split completely in half. This view is from the driver side closest to the door. I wrapped duct tape around it, maybe that will fix it until I get a new tube.

Not 100% on this, but I think that is the VAC line for the 4x4 actuator...

Is you 4wD working?

It was working a few days ago when I last used it. Good ole Nashville flooding.

Just replace it with some more vacuum line. It's cheap.

Also, it has nothing to do with your throttle position sensor.

Yea, that's what I figured. My acceleration is still messing up.

Well, I got a new Delco TPS for $45 shipped. Installed it today, and now the blazer is running like a hot rod. Especially with the new Hypertech max energy programmer!
