I have a 1996...

I have a 1996 Taurus with a 3L Duratec 6cyl. engine. The computer displays a P0430 error code. The cat. converters are aftermarket and less than 10 months old. O2 sensors and the air pump are working correctly. Ford OEM converters are no longer available. I am told that the tolerances on the aftermarket converters are not the same as the OEM ones and that Ford service can reflash the computer to work correctly with aftermarket converters. Is this true and can I schedule this service at my local Ford dealer?

Mechanic's Assistant: Have you located all of the vehicle's oxygen sensors? Are the wires leading to and from each intact and in good shape?

Yes. Thoroughly checked out dynamically while driven. This is a false indication as far as I can tell.

Mechanic's Assistant: Are you fixing your Taurus yourself? What have you tried so far?

My local shop has verified everything is working correctly. Can you tell me if a computer upgrade will solve this issue.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No. I think you have all the info. I just need to know if a software upgrade is available from Ford. From what I read this is not that uncommon of a problem.

The problem is many universal catalytic converters are not large enough to satisfy the monitor the Powertrain Control Module (PCM) runs when checking the operation and will flag the catalyst efficiency codes again. Having your computer reprogrammed works sometimes but not always. Rater then takes the chance of wasting money on trying you would be better served to locate a converter set that meets OEM standards. There are sources that still sells them.

I have Walker converters in the car now. Are these not large enough? Do you know who makes converters that will work in my car?
Customer reply replied 1 month ago
Not for $26! Let's see if we can resolve this via email.

See the source below, these meet OEM standards, when you replace one side you really should replace the set. Give them a call to verify they have the ones you need in stock.
