Two problems related to vsa warning light on have been reported for the 2005 Honda Odyssey.
While driving during rush hour traffic the vehicle suddenly without warning began to apply the brakes and the engine idled down then temporarily seemed normal only to have it reoccur in a matter of seconds. The vsa light including the symbol and the initials vsa became illuminated. I turned the car off and restarted it multiple times only to have it reoccur over and over again. I had just had the catalytic converter replaced for a second time two weeks prior to this happening. I was told by the dealer that in replacing the catalytic converter the service crew punctured my radiator and had to replace that as well. I had the car towed to the dealer who told me the vsa senor control cluster needed to be replaced. They said that they had never seen this before. They indicated that the part would take a week and a half to get the part which seems very strange. The cost for the part is $500 and the installation will be $276. 25.
Faulty vsa modulator / abs pump. The vsa indicator light stays on and diag check by dealer shows error codes 76-1 and 66-1. The advise is to replace the modulator. This equipment is already proven faulty in similar Honda models (odyssey 2007-2008) and recalled. Honda Odyssey 2005 also needs to be recalled. Customers should not be forced to spend a couple of thousand dollars for this.
