Standard resistance 
If the result is not as specified, replace the oil control valve assembly.


Notice:
Check that the spool valve is not stuck.
Hint:
The spool valve may not return if foreign objects are caught in it. This may cause subtle pressure leaks to the advance side, and a dtc may be set.

InstallationTransmission fluid temperature sensor "A" circuit
Description
The automatic transmission fluid (atf) temperature sensor converts the atf
temperature into a
resistance value which is input into the ecm.
The ecm applies a voltage to the temperature sensor through ecm terminal tho1.
The sensor resistance changes with the atf temperature. ...

Vin not programmed or mismatch - ecm / pcm
Description
Dtc p0630 is set when the vehicle identification number (vin) is not stored
in the engine control module
(ecm) or the input vin is incorrect. Input the vin with the intelligent tester.
