Error Code 31 and 34

[Jin1976]

I just had new O2 sensors installed today (the clock fuse was pulled out and inserted back again). It was smooth and car is very responsive with a little bit of throttle. After a few miles of driving the CEL came again. I got Code 31 and 34 from the TCS light and code 1 and 2 from the CEL light.

Code 31 means A/T FI Signal B error but there is no translation for Code 34. Does code 1 and 2 from the CEL lights mean error for Front HO2S and Rear HO2S?

What should I do next. FYI my rear coil pack might need replacing second time after one got water on it and the other got oil. Also I have not yet replaced my fuel filter after the first T-belt change (about 75K miles ago)

TCS Code 3-3 is Abnormal TQOUT Signal
Related components; Engine Control Module (ECM)
Wire Harness
TCS Control Unit

TCS Code 3-4 is Abnormal VREF (refernce voltage) signal
Related componants; Engine Control Module (ECM)
Transmission Control Module (TCM)
Wire Harness
TCS Control Unit

CEL 1 & 2 Code 1 is Front O2 sensor
Code 2 is Rear O2 sensor

Hope this helps. I do know that he on my 96 ... the O2's caused the TCS to shut off. When I replaced all my O2's no more TCS problems. I know this is not you issue ... but they did have an affect on the TCS.

Good luck.

My 95 threw a CEL which I just checked and it was
p0155(?), the front O2 sensor heater.
The TCS light also stays on.
How are they related?
It would be too awesome if all that is wrong is an O2 sensor.

(small note: i just finished a grouling track event today)

tcs light goes on together with check engine light, this is normal - don't know why

Thanks Xory. I'll try to reset the TCS memory by taking out the said ALB fuse tonite. Hopes it will clear the problem.
