P0430 code. Any suggestions?

Any ides? This came up last month then went away. Now it’s back.

Thanks

 

02 sensor would be my first check

 

do they usually go out before the cats?

and how do I check if they are bad?

 

you can roll the dice on an O2 sensor if you want but that code is very common when your cat is no longer efficient....

 

fuck.

I live in the Middle East. There are no laws here really.

can I just cut my cats off?

 

Buy a spark plug fowler for O2 sensor, problem solved.

 

What is that and how would it solve the issue?

 

It fakes the ECU in O2 readings.

 

ohhhhhh ok. But if my cats are faulty does this affect performance or gas mileage or anything?

 

If you are not noticing performance or MPG drop yet, can’t you keep driving it with the code if there is no emission testing in the Middle East?

 

I mean I guess so, but the code turns the traction control off.

 

Not one bit. It only effects exhaust emissions. This code is just letting the ECU know the cat. is working properly. Bank 2 is the opposite side of the #1 cylinder. Are you having any issues other than this code?

 

ISNT........

 

ohhh ok.
And nope not at all. Thats good, right ?

 

Yes, that is good.

 

'roll the dice' by checking the sensor?

Just put a multimeter across it and compare your left bank to the right bank if you cant find the exact voltage specs..

If you dont have a multimeter- swap left to right sensors and see if the code follows a sensor or stays with the same bank.

 

thanks !

I have a multimeter but I don’t know how to use it.
I’ll see if I can find a video

 

Why use a DVOM when the scan tool will give you the voltage readings and is much faster/accurate. The post O2 should be a somewhat steady voltage from 0-5 volts. Pre O2 sensors fluctuates from 0-5v.

 

On my 2nd gen, I was able to swap my sensors from side to side to see if the problem followed the sensor. It didn't. The pigtails were different length, but I was able to not use a holding clip to make it work for a day while I drove around. It was my CAT, not the sensor.

 

if we want to get technical, figured most dont have the tools...
Pid data, front 02 should be switching rapidly, cat monitor sensor / rear 02 should be steady...
If its switching rapidly it needs a cat...
another pid that will give an indication of cat is at the end of its life is oxygen saturation percentage ratios.....
