Trac off, check engine light on and 4 LO flashing

What’s up everyone? Just joined the forum. Have a 2013 tundra and installed an afe cold air intake on it and love it. Installed a air aid throttle body spaced and after driving the truck for about 6 miles, got in it to turn the engine over and fired up fine but had the check engine light on, TRAC Off lit up and 4 LO flashing. Anyone come across this issue at all?

 

Check for codes , an go from there but from the dash alone this thread has a link in it to it. But also OP referenced a code.

and welcome to the forum

 

Thank you so much for the info. And reply with the link! Much appreciated! I’ll look into the codes but I have a feeling that throttle body spacer the truck didn’t like

 

I had the EXACT same thing happen. Went to the auto parts store and had them read the codes. I had “lean fuel” on both banks. Seemed unusual to suspect the exhaust so I looked at the intake. After more research I found someone recommended ding I clean the MAF sensor in the intake. Plus they recommended a good battery post cleaning. I bought MAF cleaner and used 1/2 small can on the sensor. Then I let it dry while I serviced the battery.
So far so good. I only put about 50 miles in the truck and the issue had not returned.

 

Here is my current situation. The lights flashing on VSC OFF and 4Lo. On lights are everything else you see.


I have no idea where to start. I recently took off my 4Hi actuator (it was flashing on dash) and unjammed the motor and reinstalled. 4Hi still doesn’t work (reason for me doing the actuator) but the flashing stopped. Now all these lights pop up after driving 40 miles (i disconnected battery after doing work)

 

Go get yer codes scanned

I got the same issue. Lights came on yesterday ( VCS off and 4lo flashing, traction and CEL on) after pulling a log. I'll start by reading the codes and then disconnecting the battery. I hope it's an easy fix.

 

Have you tried re installing original parts? Throttle body spacers don't do anything on a NA vehicle.
