My 98 V70 T5 Check Engine Light just turned on. Also the flashing up arrow on the dash along with the little lights by the shifter flashing from "E" to "W".
Pulled two codes P0120 and P0123. Checked the transmission fluid. Level is ok, not dirty or burnt smelling. (It most have been changed before because it looks nice and clean.) The vo has 115,000 miles.

Cleared codes and same codes were set again right away.
On initial start up it idles high for 30 - 45 seconds or so. Then it idles back down to normal idle. TPS problem as possibly indicated by the code?
Speedometer and tach are working. Auto transmission does shift but I think it only shifts up to 3rd gear and stays there. Did a bit of the ratchet shifting others have mentioned related to PNP without any change in flashing arrow light.

Should I try replacing the TPS? PNP? Vacuum lines?

The car starts and runs fine, but it does appear to be in limp mode.

Also the ABS light has been off and on.

    Before you replace anything, it is always worth the time to clean the electrical connection and make sure it is seated properly. If you are really good, clean the TPS. If that fails, replace it.

    The TPS is also used by the tranny, that is why the shift arrow is blinking.

    The ABS module can cause the speed signal to the engine and tranny to go missing when it fails. The TPS uses the speed signal...

      Should I use some kind of spray product on the TPS to clean it?

      A different product for the electrical connections?

      It doesn't look too bad at all so I reseated the connection..Seems snug.

      Thanks for your help!

        There is an electrical component cleaner, available at autoparts stores. Also good for cleaning plug connections, etc. Use it with a Q-tip, then after it dries wipe with another clean Q-tip.

        Don't forget, the ABS module could also be a secondary culprit.

          Thanks for your help Klaus. I got a rebuilt ABS Module from FattyMatty on MVS forum.

          Pulled mine and replaced with a rebuilt unit from Matthew. That got my ABS light turned off after months of intermittent flashing. Thanks Matthew.

          However, still got the flashing arrow problem and little lights flashing by the gear shifter. Still setting the same codes. Next evening, replaced the TPS with a non-Bosch after market sensor. I noticed the TPS goes on kind of like the knob on a stove or old tv set. You may have to turn the female part inside the TPS to get it lined up with the flat side of the shaft. Reset the codes again, and so far, good for a week. No CEL, no flashing arrow and transmission seems to be shifting normally again. Thanks again for your help.
