2014 4Runner SR5 4x4 w 1900mi, just 3 months old. Went to drive it today and the Check Engine and TRAC Off lights are on. Feels like limp mode with limited acceleration.

Took it to the dealership and they didnt have time to look at it today, so went by an auto parts store and plugged in an OBD scanner. Three identical codes P1613 Secondary Air Injection System Driver.

Anyone seen this?

Sounds like it is an ECM issue. It use to be the engine will only go into limp mode when there is a risk of failure. But thanks to CA, it now will shut down because of emissions is many cases.


Below is a description of what system causes the code you are getting.

MONITOR DESCRIPTION
After the cold engine starts and it is in the short time, the ECM transmits command signals to the Air Injection Control Driver (AID) to drive the air pump and Air Switching Valve (ASV). AID detects an open or short in the air pump and ASV circuit according to the AID terminal voltage and sends a signal as the diagnostic in- formation to the ECM.
If the Secondary Air Injection (AI) system circuit or the AID itself has a malfunction, the AID sends a malfunc- tion signal (duty signal) as a diagnostic signal to the ECM (when the system is normal, a system normal signal is sent). The ECM sets the DTC based on the diagnostic information from the AID.
The ECM sets the DTC based on the diagnostic information from the AID.

Thanks for the info. I'll post here after I get more details from the dealer tomorrow. This is the first real issue Ive had with a Toyota, ever.

Interesting code with such a new vehicle...

This is going to sound odd, but check your gas cap. Take it off and put it back on with the one "click".

Is/was the truck in "limp" mode the entire time or did it go away after restarting and just leave the "check engine" light on?

Super lame dealer.

Tried that first thing, no luck.

Entire time, several restarts later, same thing.

NICE !!!!!!!!!!!!!!!

Mice? Squirrels?

I dont know what kind of varmint, but he did a nice job on it! Dealer quote is $4300

Man I am so sorry.

Looks like a I need just the light blue harness, mostly contained to the engine bay with a little bit of work inside the vehicle behind the kick panels and instrument cluster. Toyota p/n 82111-35Q10 MSRP $2,653.43.

Insurance is going to cover it, but I hope there's no long term issues.

Nice that insurance is covering it. Reminds me of a friend with a C32 AMG. Critter chewed up the wiring harness between the motor and firewall. Engine had to be removed to replace.....it was not cheap :-) Darn squirrels!

Sorry to hear that! $4300!!! Glad insurance is covering it! Still you're out the deductible, which stinks.

Maybe it's time for a Havahart trap...or a .22LR :P
