Vtm-4 light, check emissions light, sluggish, loud engine.

Customer Question

vtm-4 light, check emissions light, sluggish, loud engine. Happened with previous 2 Honda pilots as well when pulled very small trailer in mountains. frustrating
JA: Does the light stay on, or does it blink?
Customer: vtm-4 light doesn't blink, but not always on, just intermittent, check emission controls is steady on
JA: What year is your Pilot?
Customer: 2014
JA: Are you fixing your Pilot yourself? What have you tried so far?
Customer: been to my mechanic 2x, first time he changed oil and pulled codes - P3400 VPS stuck off. Cleared, thought was good, but lights came back on after short drive. Back in today, they manually reset the VPS (does that make sense?) thought it was good, but I was running errands and lights came back on after short drive. Scheduled to leave car with them next Monday, just trying to research
JA: Anything else you want the mechanic to know before I connect you?
Customer: don't think so...

Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

The vtm 4 ight is an indication that the computers think the vehicle is losing traction.This is also related to the sluggish issues since the computers will start to pull back power from the drive wheels as it thinks it is slipping on a slippery surface.Is this code still setting?

Let me know,thanks Pete.
