Code 25
I've looked but can't find this exact issue.
'92 SC400, bone stock, high mileage ( 422,000 km, but who's isn't?)
Replaced the upstream oxygen sensors within the last 5,000 km.
It throws a code 25 occasionally, but only after prolonged highway use at 100 - 120 kph or more, then stopping, say, for lunch, when the engine cools down. As the operating temperature rises back to normal, and it has never overheated, the code pops up and then shuts off at normal operating temperature.
Anyone else experience this?
