Default P0705 code help 08’ rx350

Anyone run into this problem? Prior owner had a remote start installed but don’t know from how long ago. Looking at the fob maybe 2009 era compustar 1 way remote.

Weird other lifts on also p0705 transmission range sensor A circuit

Check the PRNDL switch on the transmission.

Ok giving it a try.

Does the gears match in the intrument panel cluster when shfting thru gears? (signal to cluster gear position info is received from gateway ecu- no direct path from cluster info to shift linkage so linkage adjustments and connector corrosion, etc to switches can matter).

>> Here is the part of the code that suggest it thinks it is in more than one gear position simultaneously- possibly located in pic above.

P0705 "...The park/neutral position switch sends a signal to the ECM according to the shift position (P, R, N or D 3*1, or 2*1). The ECM determines that there is a problem with the switch or related parts if in receives more than 1 position signal simultaneously. The ECM will turn on the MIL and store the DTC."

If problem still persists just thinking maybe can something to do with aftermarket remote failure with custom wiring into Neutral Switch or something who knows but need more info/details.

exactly my thoughts. I will need to disassemble car remote starter then go from there.
the light does not illuminate once put into D or if swiped left to 4 position. All other gear points illuminate.... vehicle has always started , never a no start. I thank you and other person for feedback.
mom limited time info in Alaska lol.
