Vtm-4 and check engine light on honda pilot

The Honda Pilot's all-wheel-drive system is pretty clever, with variable torque distribution between its front and rear axles, as well as between the left- and right rear wheels. It generally works well and ensures strong traction on difficult roads - but some issues have been reported over the years. Their modes of operation are very similar, though, with the newer i-VTM4 essentially just adding more intelligence to the rear-axle torque distribution algorithms for improved agility and better stability in extreme driving conditions. But what if something goes wrong? First, let's look at what VTM-4 is. However, it's important to note that there is a clear distinction between the gauge-display-mounted VTM-4 or i-VTM4 warning light, and the confirmation light inside the dashboard-mounted VTM-4 switch, to the left of the audio system. The VTM-4 warning light in the Honda Pilot's instrument cluster should only illuminate when starting up the engine, following which it should extinguish within a second or so. Thereafter, it's supposed to remain off, even if the clever rear differential is called to action. If the VTM-4 cluster warning light switches on while driving, it indicates something amiss with the rear differential operation, which can be due to a surprisingly wide array of possible causes. However, the confirmation light should only be illuminated when you have purposely engaged Lock mode, and the button should be pressed again to disengage Lock as soon as it is no longer necessary or when returning to hard surfaces. Doing so will turn off the confirmation light, and all will be well. Reasons why the VTM-4 light on a Honda Pilot could illuminate vary; from easily-remedied issues with the wiring harness or sensors to being part of a much larger set of problems, including:. First-generation Honda Pilots will most likely illuminate the VTM-4 warning light due to insufficient differential fluid or a sensor error, with and model year examples reportedly being most prone to these ailments. Second- and third-generation Pilots and model years, respectively share these possible causes but add the possibility that there may be engine- or emission-control problems, in which case the AWD system will automatically disengage and switch the warning light on.

The problem my car had was fixed by replacing the plugs at around 93k instead of the recommended k. Heard something "snap" and the loud flutter sound like a belt snapped.

Take apart and clean. I've gone online to view this 02 Sensor. Email this Page. My solution has been to buy an inexpensive reader tool and keep it in the car so if a problem shows it's self I can read it on the road and reset it as needed. I didn't stop until I got home. If the O2 sensor doesn't come off with the O2 sensor tool, just clip the wires and use a deep socket. Everything is working well. This alone is enough reason to pull over when the VTM-4 warning light starts flashing!

In about a day or so they both will go away? The check engine light is on on my Honda Pilot. Mine was a code specifically for misfires that was tracked down to some dummy "professional" repair shop installing the upper intake manifold gasket upside down. The CEL is still lit. I like to have an O 2 socket, because not only can you use one to remove the O 2 sensor, which can also be done with a deep enough socket and snipping the old wires if necessary, but it's gosh-diddly useful for installing the new one. It came on when I was driving one day. Posting Quick Reply - Please Wait. Can I replace the sensor myself? So i change my car injector but vtm-4 light still Ep3 Check engine light problems.
