Question about 1996 Lincoln Town Car
I found what this code was EGR CONTROL CIRCUIT..Could this be a bad EGR Valve/Solelinod
Yes that is cat efficiency code for the bank2 (drivers side cat). When the PCM runs the cat efficiency monitor it compares the switch rate of the front O2 sensor with the rear O2 sensor to determine the ratio. If it falls below a programmed limit this code will set. There are usually 2 things that causes this. First is a lazy front O2 sensor, if your front O2 sensors have not been replaced in a while I would try replacing them first.
2nd is a bad catalytic convertor. If replacing the front O2 sensor does not correct your problem you will unfortunately need to replace the cat.
