Light trifecta today

Fired the truck up today and check engine, maintenance required and traction control off lights popped on. Brought it to the shop and they said vacuum leak and return truck after it cycles through. Any ideas?

 

What was the DTC?

 

They didnt say. Just told me me to cycle and return if light comes back on. I just swung by at lunch and they threw it up on the lift for 20 minutes.

 

Without a code it could be anything ​

 

Id put money on an ABS or wheel speed sensor.

 

Thanks i will look into it as soon as a get home

 

No code number but its tripping evac code. I am thinking some bad gas or left my cap open. I didnt read my slip but they want me to go back next week after cycle to complete my yearly inspection.

 

I too just had the Check Engine Light and Trac Off Light come on , scanned and got a P0441 code for Evap Leak! Changed Gas Cap with OEM from Toyota. After market does not help sometimes! Light was out for 3 days and then came back! Next solution was the EVAP Canister Purge Solenoid next to PCV and changed that out! Been a week and recanned, no codes ,no Lights ! Hopefully Fixed for good!$22 for OEM Cap,$50 for EVAP Canister Purge Solinoid! If a P0411 Code ever comes on, it will be the Secondary Air Pump next to Air Filter House. That would cost $80 on Amazon and $800 at Stealership or Parts Stores! For Air Pump, Go to AMAZON !

 

bing bam boom

 

I ended up with just a new evap cannister.

 

Just an FYI the secondary air pump has nothing to do with the evap system MILs. They have to do with a fuel system leak. The air pump is some BS that the government added to reduce emissions, that in reality does nothing because the system breaks and is full of non organic products that are constantly required to be replaced due to poor design hence it completely negates their "emissions reduction initiative"
