2008 CTS Cadillac 3.6 stick ,have 2 po430 code 02S and EVA, put a new cat on old one was empty checked every thing was told cat,out on new now has 2-430


Sounds like you need a reputable mechanic with a good code reader to check it out. It could be an O2Sensor, I would almost bet on that one, but could be many other sensors as well. O2 sensors emit low voltage signals and if one is weak or bad it will act like the Cat is bad. make sure the wires are plugged in all the way, possibly one is loose from when they installed the new cat. Hope this helps. Hard to diagnose with out the vehicle here to hook up my code reader to.

the HO2s sensors are before the cat convertor and the O2 sensors are after the cat converter.

Code 430 means the catalytic converter for bank two is not performing at a normal level. The problem could be the cat or something in the fuel system. The computer uses the data from the front and rear O2 sensors to monitor the performance of the cat.

Motor will idle but when you push on the foot accelerater, nothing happens. no power and idles rough. catalytic converter? 2008 f450, 6.4


The cat. should not be plugged on a truck that is only 3 years old. might be faulty ignition component(s). Check inside distributor cap for moisture or metal particles. dim or turn off lights in garage and spray a fine mist of water from a spray bottle over cap and spark plug wires take note of any arcing of spark. this could indicate faulty plug wires. GOOD LUCK. If it is the cat. that is bad on a truck this new it is a symptom of a bigger problem.

Jeep 2008 Commander 5.7 code p0430 What does this code mean? Thanks,


code --catalyst system efficiency below threshold bank 2 -means that the o2 sensor [bank 2 and after cat converter] is detecting that the converter in not working efficiently as it should as per specs--check the 02 sensor --if good possible exhaust leak if good --possible cat converter gone bad and since it is an 08 cat should be covered under warranty check with a dealer most converters are covered for five years doesnt matter how many miles on vehicle
