850 Getting A1 socket code 311 with flashing arrow Please Help! 850

posted by  someone claiming to be Ed on  Sun Dec 30 11:53 CST 2007 [RELATED]

I have a 95 850 and I keep getting a flashing arrow and then a check engine light when driving. When I pull the code from the A1 socket I get 311 only. I tried clearing it and it returned. I replaced the two wire transmission speed sensor on top of the trans held in by one torx screw with a known good used one from a parts car I have and cleared the code. Drove it 2 miles and it returned.
Is the another sensor that code is telling me to replace?
Thanks in advance for any help.
Ed
