Emissions

Good afternoon.

Lets start with the code number?

Give me the number and I will get the information for you.

Okay, that codes indicates a failed cat converter for bank 2.

You need a new converter. I attached some possible parts for you to view. The catalytic converter is one assembly that contains both cats. One for bank 1 and one for bank 2.

430

P0430
Descriptor
Catalyst Efficiency (Bank 2)
Probable Causes
(K902) Oxygen Sensor (O2S) Return Upstream Circuit Open
(K902) Oxygen Sensor (O2S) Return Upstream Circuit Shorted to Ground
Catalytic Converter
Engine Mechanical Condition
Engine Mechanical Problems
Exhaust Leak
Oxygen (O2) Sensor
Oxygen Sensor (O2S) Deterioration
Oxygen Sensor (O2S) Return Downstream Circuit Open
Oxygen Sensor (O2S) Return Downstream Circuit Shorted to Ground

That is not a list of parts, it is possibilities only.

If you do not have an exhaust leak, then it is the catalytic converter. Roy

If you had one, it would be loud.

To find it, have someone hold there hand over the exhaust pipe at the rear with a rag in there hand and look for a rush of air. That will be the leak.

Roy

You need to get under the truck with it running and someone blocking off the exhaust at the rear. Look, feel and smell for the leak. You need to get up and close.

Roy

No, it will not. They usually last about 100,000 miles and they wear out.

The only other factor is a poor running engine with misfires. That melts the internals but you would have complained about other engine related codes.
