I had my exhaust done and got the exact same code.
P0430-CATALYST EFFICIENCY (BANK 2)
For a complete wiring diagram Refer to Section 8W.
Theory of Operation
The State of Change (SOC) catalyst monitor uses the signals from both the upstream and downstream O2 sensors to detect aging of the catalyst. Based on the fact that when a catalyst ages, it loses some of its Oxygen Storage Capacity (OSC). As a result, part of the untreated exhaust gases can breakthrough the catalyst and causes the downstream O2 sensor to deviate from its neutral (Stoichiometric) position. By observing the activities in the downstream O2 signal, the degradation level of catalyst can be detected. In general, the higher the downstream O2 sensor SOC value, the more exhaust gas breakthrough and the lower the OSC of the catalytic converter.
When Monitored:
Engine coolant temperature above 70°C (158°F), engine RPM between 1400 and 2300 and vehicle speed between 30 and 60 MPH.
Set Condition:
If the final State of Change index is within the calibrated fail threshold. Two trip fault. Three good trips to turn off the MIL.
Possible Causes
EXHAUST LEAK
ENGINE MECHANICAL CONDITION
AGING OR CONTAMINATED O2 SENSOR
CATALYTIC CONVERTER
The 430 is passenger rear o2.
I had a tiny little exhaust leak on the top of the weld just after the pass side cat just before the O2 sensor. i took it back in and they corrected the leak and no more codes. find the leak and solve the problem.
