Hello and welcome to Just, Super mechanic here. About your vehicle.


The P0700 code is a request for the MIL, (check engine light) to come on. The P0705 would be the reason for the request. That code is for the transaxle range position sensor, (PRNDL input)


That is probably a bad TR sensor, (trans range sensor) however, here is the test for it.



DTC P0705: Transaxle Range Sensor Circuit Malfunction (PRNDL Input)



Circuit Description
The Transaxle range switch is located on the selector shaft and informs the TCM of the current selector lever position P-R-N-D-3-2-1. The selector lever position is transmitted to the TCM in encoded form along 4 lines. The encoding is such that malfunctions in the connecting lead are identified. The TR switch is located on the selector shaft, which is connected to the selector lever via a pull cable. In addition, the TR switch controls the starter interlock, the reverse lights and the selector lever position indicator on the instrument panel.













Diagnostic Aids
When DTC P0705 sets, the possible cause is TR switch.

Is it still save to drive till we can get the trans range sensor fixed. Thank you for your help.
Expert:  Jerry replied 6 years ago.
It is safe, however, you don't want to drive too far without making sure that the trans is shifting okay and that it's not in a "limp mode". Also, that the connector is on at the trans and not loose.
