Hi,


Regarding Rough Idle, that might be due to misfire. a tight valve would set random miss fire codes and cause a rough idle but since this just started after the timing belt replacment it leads me to that area first. but if your 100% positive then you can look at the valves but the fuel trim is lean on both lt and st which i have seen this same condition and has been resulted to belt timing. Check and let me know.

Thanks for using "Fixya".

My husband said that the VTM-4 light is on in his 2001 Acura MDX. We were on our way to the transmission shop because the transmission is being rebuilt. What causes this light to come on?


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.

My check engine light and vtm light are on in my 2008 Honda Pilot I checked the codes it's saying the egr valve is bad would that cause the Vtm light to come on to


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.

My question is on my acura mdx 2003. The left front wheel was worked on and somehow the mechanic damaged the sensor there. I guess the abs sensor. This made the ABS, VSA,VTM-4 and a triangle light came on....


When you clear the codes and the problem has not been fix after 10 miles of driving the warnings return. I am sorry but I am not sure what is causing the indicator lights. Have you looked up all the remaining codes?

WHAT IS VTM-4 LIGHT?


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.

Vtm & check engine light on same time vehicle idles 25K, 2001 MDX


Im not quite sure about the lights but when changing the alternator the battery cables would have been off resetting the settings in the engine computer. let it run for a little bit to get readjusted and it should idle down on its own and be fine.
