I got check engine light and vtm 4 light on my

wow no engine told at all.nor VIN, double wow
cylinder bank shut downs are a feature to save fuel and is complex
read why here/.
part of VVT and guess what bingo that, may be failing.

https://www.obd-codes.com/p3400

the VTM-4 relates to torque management for the 4 wheel drive / all wheel drive part of the transmission. I have had people tell me more than once that that VTM-4 issue went away after having the cylinder head valves adjusted.
A little google search may back this up.

Yes, the VTM-4 module will light up.

Here's the deal; when you manually turn on the Variable Torque Management-4 system, the light to the console switch is illuminated- letting you know that the vehicle is in traction control mode- and it is functioning properly.

However, if you did not manually activate the VTM, and your cruising along under normal driving conditions, but you start experiencing engine problems, like when the Exhaust Gas Recirculation valve starts to malfunction, this malfunction will cause the engine to misfire and lose engine power.

When this loss of engine power occurs, the VTM perceives that the engine power is being reduced to restore traction to the car's drive line (axle and wheels)- so it triggers the light to go on.

The triggering of the VTM could also happen when the idle speed control valve malfunctions.

So once you have the EGR valve replaced, the codes on the OBD module should be cleared; the check engine light will turn off; and the VTM system light will turn off too.

wow, 2007 and 2012 in one blue box....
or open the glove box, extract operators guide,

VTM-4 lamp (your 4wd?)
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. If it comes on at any other
time, there is a problem in the 4WD
system. Take the vehicle to your
dealer to have it checked.
If the indicator blinks while driving,
the VTM-4 fluid temperature is too
high. Pull to the side of the road
when it is safe, shift to Park, and let
the engine idle until the indicator
goes out.
Continuing to drive with the VTM-4
indicator blinking may cause serious
damage to the system. (end page70)

if really DIY guy?
the then the FSM elaborates this to no end.

buy the FSM and read that. (most things on most newer cars are anything but simple)

Hi, An '09 should be under warranty or I'd least take it in and 'nicely' ask that it be covered under warranty.

This LINK may help w/the VTM-4 info...but not sure about the EGR.

VTM-4 LIGHT is the 4x4 option you can use when your in the auto shift gears 1 and 2. When you put the shifter in 1 or 2 gear, you can push the VTM-4 button on dash and you will engage the 4 wheel drive constently. If you switch out of 1st or 2nd gear it will disengage automatically. The VTM-4 also works in reverse gear. Hope this helps.

If it says VTM-4 that is your VTM-4 indicator:

This indicator normally comes on for a few seconds when you turn the ignition switch to ON (II). If this indicator comes on at any other time, there is a problem in the 4WD system. Have your vehicle checked by a dealer.

The Variable Torque Management 4WD System (VTM-4) automatically transfers varying amounts of engine torque to the rear wheels under lower traction conditions.

You can try the following:

To Disengage the VTM-4 Lock, do one of the following:

1. Press the VTM-4 Lock button.

2. Move the shift lever to D or D .

3. Turn the ignition to LOCK (0).

The VTM-4 Lock will temporarily disengage when the vehicle speed exceeds 18 mph (30 km/h). It will automatically engage again as the speed slows below 18 mph (30 km/h). The button light will remain on.

Hope this helps you understand the light. If not, leave a comment and I will try to help you further.

Your wheel bearing is the fault.Get it changed ASAP.Good luck hope that was helpfull.

Sounds like the EGR valve's gone. Not a terribly expensive fix.

Bring it to a dealer immediately. VTM-4 means the 4WD is off, possibly because of the engine line or vice versa.
