I’m trying to figure out a traction control issue on a 2006 Honda Pilot, where the TCS light comes on for a second or so and the SUV has no power/won’t accelerate. There is almost no pattern to it. It could happen accelerating, cruising, or slowing down (but it’s only really a problem accelerating), while turning or going straight… At times it seemed to have a pattern: for a while it seemed to go off quite often when going through a specific intersection at speed and hitting a dip coming out of it or in one particular LH turn, but when I tried to confirm it I wasn’t able to, it just happened more than once in a specific spot. It can happen as often as a few times a trip or as little as 2 weeks apart.
There is no service light lit up, and I’ve hooked up a scan tool to check for stored codes, there aren’t any. I also tried to see if I could see odd speeds at the wheel sensors but after trying 4 different scan tools I can’t get any of them to show me that or any CANbus data.
Looking for advice before I fire the parts cannon at it (maybe replace the wheel sensors?), has anyone seen this, have suggestions on what to check or how to figure it out? It’s happened enough times in DC Metro rush hour traffic where it’s come close to causing an accident (a car that should be accelerating is suddenly slowing down with no brakes) that we’re considering selling an otherwise mechanically sound vehicle that we like.
