P0421 DTC in my Mazda Premacy 2005
Hi Friends,
I have an old Mazda Premacy. It has Check engine light on. I have checked for all possible failures have found nothing.
I have only 1 dtc in my CAR P0421 no other error code.
I do not understand should I invest in catalyst or not.
I do not see any misfire or problem in driving the car is very smooth.
Please help me to diagnose and solve the problem.
Regards,
Saurabh
