Output Shaft Speed Sensor

[deepseavoyage]

Once again I am having problems with my boxster. I am getting codes P0722 Output shaft speed sensor circuit no signal. Shifts hard then goes into limp mode. Tranny oil is less than 10000 miles w new filter. I noticed that if I shift with tiptronic it shifts better but on the down shift it does not respond and gear shift lights go up to 5th gear and stay there till complete stop then they go down to 1st gear a slight hard shift will send i t to limp mode which by the way resets when car is turned off but limps again on a hard shift. It also has codes P0650,P0430,P1128,P01130 which I will have to clean the catalytic converter and clean or replace the MAF. Any one have an idea on the Output shaft speed sensor??

The transmission issue could be oil getting into one of the transmission electrical connectors, which will cause this issue. If you find oil in a connector, clean it thoroughly as AFT can cause these connectors to fail, which gets expensive.

Planning a thorough inspection tomorrow and will certainly look at that closely,thanks JFP.
