Code p0430

Hello, I'm Danny.

The code P0430 is for bank 2 catalytic converter inefficiency. Here are a few tutorials showing catalytic converter symptoms, testing, and replacement:

Due to having a faulty oxygen sensor up until replacement it may have caused damage to the catalytic converter. I've attached picture steps below on removal and replacement on your vehicle. I would have them tested first before replacement. Hope this helps and thanks for using 2CarPros.

Thank you.

Which o2 sensor is under engine oil pan then? It's on the passenger side. thank you

Hello again.

Your vehicle has 4 oxygen sensors. There are 2 sensors on each bank left and right. One is upstream and one is downstream. I've attached photos for you below. Hope this helps and let us know if you have any further questions on this issue. Thanks again for using 2CarPros.

I'm sorry bother you. so the bank 1 is on the driver side or passenger side? And then bank 1 sensor 2 is upfront?

Hello again.

Bank 1 is the cylinder bank closest to the firewall-windshield. Sensor number 2 is the lowermost sensor towards the back of car. Attached pictures again below and circled in red. Hope this helps and let us know if you have any further questions on this issue. Thanks again for using 2CarPros.
