P0421 code bank 1 warm-up efficiency below limit


P0421 code is that the cat. converter is below efficiency. 99 per cent o the time the cat. needs to be changed. but if you have a scan tool watch both bank 1 O2 sensor 1 and bank 1 sensor 2.
cold they should be almost the smae but when its at operating temp, and running down the road at crusie speed the frt o2 should switch rapidly between .150 mv. and .850 mv. and the rear o2 should read about .600 mv. if they read the same the cat is ng and will have to be replaced.

I am getting a P0031, P1512, & P0421 code


P0031 - most likely pointing to a failed O2 sensor (bank 1 sensor 1 is located before the catalytic converter)

P0421 - failed catalytic converter or a failed O2 sensor

P1512 - intake manifold shutter valve is stuck - may be caused by the O2 sensor, but may not

I recommend replacing your O2 sensor first and see what happens

I have a 1997 Mazda Millenia bought it used. Anyway like 2 days ago a light switch came on (ACS) I don't know what that is and it's been wanting to stall out. Do you have any idea what it might be?


go to autozone & check the code for free mazda millenia they all have problem with the check engine light problem even though you bought all new parts it will still show , but never replace the cat converter most cause the engine light is the sensor only.

P0421, P0431


Technically, you can put the car in neutral and press the gas while the car is running, til it reaches 3500 rpm. You don't have to actually have the car on the road while you do this.
