Help needed, limp mode , etc...

[waveslayer]

So 2 days ago I head out with a few guys to hit up Anza-Borrego. As we get there I start to air down a bit and all these little alarms start to go off... truck goes into a total limp mode. I unplug the battery, clears the codes and we are off. It did it 5 different times, all at random, driving it, idling, etc.

The last time I was driving on the highway and it did it the 5th time. I take a video, know dealerships won't believe crap.

I go to lunch, it resets itself.

Dealership has had my truck for 2 days and can't find any problems, no codes etc... they told me to come pick it up and I'm SOL and their hands are tied. So I get to wait until I'm stranded in the desert...

you running a tune? mess with anything electrical at all? have you visually checked places where the harness is exposed to see if something damaged it?

what codes is it throwing ? might want to buy a cheapo obdII reader to catch the codes when this happens, that might give you an idea of where to start troubleshooting.

No tunes. I will check all the connectors. It's so random.

Another forum member had a collection of weird codes and limp mode. Turned out to be a rodent chewed harness. The codes would help us help you troubleshoot though. I'd also check the air box lid and the intake tubing .if a/f and throttle position don't line up, things get screwy.

What was flashing on the screen was , hill descent, advanced traction control, service code, collision control, hill start control, airbag light, and loss of power...

Only 6K miles.

check to make sure that you didnt kill an abs ( wheel speed) sensor. I had similar weird codes when my brake rotor ate one. ( i dont run dust shields anymore).

I was just about to type that in; didn’t we have someone just lose one of these to a rock or something?Not a giant boulder type rock, the kind that gets kicked up by your tires.

Using Pedal Commander?

I carry 2 spares on runs now. its a super quick 5 min swap of a sensor and carrying them has already saved a trail day for one of my buds. IIRC the replacements are $17.

It is also completely workable to splice the cut one in a pinch. they are literally 2 wires ( + and -) and when I first ate through one, my makeshift splice held for 2 subsequent runs ( while I waited for the spares to show up as no one semi-locally had them or could get them sooner than tasca.)
