85K on 2005 Odyssey. Maintenance Minder in Owners Manual states I should receive a Code B4 when the TB requires replacement. One dealer stated to wait until the B4 code comes on but NLT 105K. Another dealer stated the TB should be changed at 7 yrs or 105K which ever comes first. I am in the military...many miles related to cross country vacations and moves across the country. So would assess driving between moderate and severe but definitely not in 100 degree F on a regular basis. Should I wait until the B4 code comes on? Should I do it now at 85K miles?
