Question

I have a 2004 ford ranger 3.0 liter and engine light on reading code p0434 but it runs just fine, will they be any symptons other than engine light on? if it goes unanswered,if so what are they?

Answer 1

P0434 Heated catalyst temperature below threshold (bank2)

There is no other symptoms other than the check engine light being on,what you have is a non operation catalytic convertor. and the vehicle is a contributor to pollution
