4low flashing and check engine light with Trac off

Hi There I had the 4 low flashing with check CSC system. I recall it was error code P033 which means knock sensor or a short in the knock sensor.

Mine ended up being a cut wire of knock sensor # 4. These sensors are located under the manifold there are 4 of them.

I have another post showing the cut wire and the locstion.

Thanks

Jay

Truck has gone into "limp" mode a.k.a safe mode. you need to have a dealer read, then clear the code/s for you. only then will you know why they came on. if however you have your own reset tool, then you can manage this yourself.

Yep
When the dealer changed the oil they turned the supercharger off.
Thanks
Limp mode sucks btw

How does one "turn off" the supercharger? i ask because in recent testing my truck would not even start when the UNICHIP was unplugged

Very easy to clear the code if you have an iphone/andorid with dashcommand software

Simple on off switch mounted to fuse box.

I don't understand the simple switch. I changed fuel supply, plug heat ranges, air induction, added SC, changed injectors, custom mapped a new ECU and changed exhaust. And this can be neutered by a simple switch? How?

 

[John]

Got me. I'm guessing based on where the wires go the switch controls the new o2 censors and possibly the supercharger module. Maybe I can get Micah to chime in on this

the only switch that i have under the hood is the one for the UNICHIP and that is for high ("1") and normal ("0") octane gasolines. i am at a loss with re to the switching the SC "off" as that would change a lot and the car would feel totally different when driven.

LOL at the Back and forth.... a Switch to turn a SuperCharger off?!

The switch is for the fuel mapping on your chip ( perhaps its a three-position with a null+ two fuel maps). There is absolutely no way to "turn off" a roots style belt driven supercharger.

Agreed and also confirmed by Sparks TRD
