You are watching: 2003 honda pilot vtm 4 light on

I have a 2003 Honda Pilot130,000 MilesAll Maintenance performed on scheduleNew timing belt & spark plugsENGINE INDICATION LIGHT and VTM-4 light come on simultaneously - both are SOLID lights (freeway
60 Mph)VTM-4 Light will go off when engine is restarted & come back on about 10 minutes into driving it.I had to wait a week to get it in to the mechanic. During the week, the Engine light went off on it"s own ... hmmmWent to mechanic to find the codes were clearedToday, Engine indication light started flashing and the VTM-4 light came on SOLID. (traveling on freeway at 60Mph)Stopped the car, turned it off ... felt abandoned ... waited 10 minutes, restarted the car:ENGINE LIGHT: SOLIDVTM-4: OFFWhat is going on????? Dealer said I have to wait a week to get it in ~ they don"t seem concerned ... perhaps they"re hoping it"ll breakdown & I"ll by a new car?????? Any ideas????
Mine did thatMine did that, when a RAT made a nest under the intake manifold. Apparently the anti-knock sensor is right in the middle of Mr. Rat"s nest, so he chewed it off. The dealer told me this was not uncommon for Pilots and Odysseys. I think it was close to $400 to fix.Jeff
Run to your auto parts store and get a OBD II code scanner. I hemmed and hawed about those lights coming on and borrowed a code scanner. It turned out to be the EGR valve in my case but it could be something as simple as a tired gas cap seal. Get the code and you"ll know if it"s major/minor consider that the code reader paid for itself when it"s something simple like the gas cap.I ended up buying what I borrowed. A scangauge II. It"s a real nice toy to tweak your driving habits into getting better mileage.

I also had this same problem, but in my case it happened on a road trip, 300 miles from home. I had just fueled up at a gas station where the mid-grade was cheaper than the regular, so I used it. It must have been cheaper because it was so old they were trying to get rid of it. The lights came on less than 5 minutes later. Some normal gasoline and they eventually cleared themselves.I"m not saying this is the only possible cause - only that those two lights coming on SEEM really serious, and they may not be. My guess is something emissions-related, but the possibilities are many.
