My speedometer quit and service engine light came on. Followed by my car shifting eracticaly at low speeds. Actron obd2 says vehicle speed sensor bad. Replaced sensor cleared service enging light. Light is now off speedo still not working and will not shift out of first.

Can you see live data in that scanner? Is the speed sensor sending out the correct data? You might need to use a better, perhaps an OE scanner to diagnose it properly.

Thanks for your help. No we can not see live data and we do not know if the new sensor is sending out the correct data. Any suggestions other than OE scanner?
Without reading live data and see if the sensor actually processing and sending signal back to the control module it can't be diagnosed correctly, it will be only a guess game.
I have seen scanners gave vehicle speed sensor codes while the real problem was a transmission in or output speed sensor. Sometimes cheap scanners fails to interpret factory trouble codes to OBDII DTCs. That's why I'm suggesting a better diagnostic computer and a shop who has the troubleshooting chart and knowledge to diagnose this problem.

Ahh.... After installing new speed sensor to no avail, manually found rack and pinion hose was rubbing on vehicle speed sensor wire. Reconneced wire and that fixed the shifting, speedometer, and average speed mode. Fixed with three days of head aches and a sixteen dollar part. Thanks again for your help
