you need a scan tool to monitor the upstream and downstream 02 sensors on bank 2 more than likely its the converter. also check for exhaust leaks before converter . Most times the problem is the Downstream O2 sensor2_bing.gif is defective.

I have a 1996 Ford Taurus GL, and the temperature gauge fluctuates up and down and i replaced the water pump replaced and all that other stuff, and than the check engine light is on and I have disconnected...


P0420 and P0430 are catalytic converter codes indicating that the converter isn't working properly. Temp gauge fluctuating can be caused by a bad thermostat, bad temp sensor, bad wiring harness to the sensor. Also check for air in the cooling system. Read the post below for more information on the catalytic converter issues.

How do I repair obd code p0430 bank 2?


P0430 means that the O2 sensor behind the catalytic converter is detecting that the catalytic converter is not functioning properly. This can be caused by a bad sensor, and exhaust leak or the actual catalytic converter is bad. Check for leaks 1st. The sensor is changed by unhooking and unscrewing it from the exhaust pipe, the catalytic will need to go to a repair shop. Hope this helps, let me know.
