What is average life expectancy of a catalytic converter on a Toyota Previa?
Well a common rule that most people don’t do or realize is when the O2 sensor is found to be bad it can fry the C.C and if a C.C is found bad it’s for sure that the o2 sensor is bad too.Some change just the C.C for example and end up frying it again. To me it’s smart to change them both if codes and checking them states their no good, plus you’re at almost 100,000 kms and on average most o2 sensors go by 150,000 kms so it’s quite possible that both are in need of replacing or simply it makes sense. I’d be calling around for those parts and seeing what is the best price you can find not just for them but for the labour too.A good price is about 40 to60 tops for labour for the changing of the C.C and about 20 to 30 for the o2 sensor labour. Hope that helps and best of luck.
