Question about 1998 Ford Explorer
I have a check engine code of PO430. What does this mean? Can it be fixed? Can I still drive the vehicle without causing more damage? Where do I go from here? Thanks, LS
P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
What does that mean?
Basically this means that the oxygen sensor downstream of the catalytic converter on bank2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.

A code P0430 may mean that one or more of the following has happened:
Possible Solutions:First, inspect for exhaust leaks.
Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it.
One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

Illuminates when the ignition is switched on. It should extinguish as soon as
the engine starts.
If it illuminates with the engine running, it indicates a malfunction with the engine management system. Have this checked as soon as possible.
If it flashes when driving, reduce the vehicle speed immediately until the light illuminates constantly. If it continues to flash, avoid heavy acceleration and high engine speed, stop the vehicle and have it checked immediately.
On some vehicles this light may be red - again stop the vehicle and seek assistance.
If it is safe to do so, try stopping the vehicle, switching off the engine, wait two minutes, then restarting the engine to reset the engine management system.
With the light illuminated, the vehicle is still safe to drive as long as no other faults are apparent with the engine. Have the vehicle checked by a dealer or garage as soon as possible to avoid any damage being caused to the catalytic converter
