make sure the sensor is correctly mounted flush with the transmission body. check connectors and wiring for damage. if it is intermittent open or short in signal or a low signal you will get this code.

i have already checked for intermittence condition and short to ground & short to voltage , and all find normal, also i made a new harness between the 20 way connector to TCM and test the vehicle still there is problem.so i checked the supply voltage to tcm by probing the wire with fluke meter and roadtested,and there is no cutting off the supply voltage while the concern occurs.Also i changed the inernal harness of the transmission and still problem persist.Also i inspected the harnees for any misalignment and input shaft face damages all found normal.
pls reply

tap into the sensor output and monitor the output signal. using an O scope would be best . if the signal drops out or has a low amplitude/improper shape then the transmission encoder wheel may be broken or damaged some how.

hi

As we dont have O scope,i removed transmission again and checked the input shaft and found that input ,shaft came out around 2 mm also i compaired the input shaft so that i confirm that it was the root cause for the complaint.
Thanks for your kind advice

thanks for your feedback with this issue . you problem is not all that common here in the states.

with your detailed description of prior work completed , it had to be inside the transmission .
