Check engine light on. 850 1995

thanks for the responses,
He has replaced the PNP switch and the ABS module and the VDO speedo assembly, the wheel speed sensor have been checked (I replaced the rear wheel sensors last year but not change) but something is still not right. he gets a 323? code, says sensors are sending a code but not getting to comp.? Comp. is bad? or wires to units bad? Could there be any conection between not being able to reset the service light and the check engine light.
Info is hard to relate to you. I sent the email to him.
Thanks
Trana
