I've got a P0705 "Transmission Range Sensor 'A' Circuit (PRNDL Input) Code on our 2014 RDX. Thought it might be a simple fix, but Rock Auto doesn't list the part and I've not yet determined where it's located for this car.
It's driving and shifting fine with only a rare occurrence of a mild clunk going from Reverse to Drive. Rare being only about 3 times in 3 years.
Anyone have any experience with this one? Thanks for your support!

@samiam_68 Actually and emphatically.... YES!!! In fact, let's just say that due to a "reluctance" on the part of certain family members to use travel mugs with lids on the morning commute, the shifter is quite often (perhaps weekly) drenched with a coating of decaf coffee infused with some type of dairy-based coagulant . If the PRNDL sensor is, in fact in the console around the shifter, then I can absolutely handle its repair as soon as I can procure the part. My fear was that the "Transmission Range Sensor" throwing the code might be imbedded in the transmission from what I had read on another post somewhere indicating that replacement on "newer models" was more difficult and costly. Being that I could not locate the part on RockAuto or O'Reilly I (perhaps incorrectly) assumed it might be a more difficult repair.
@samiam_68 -- Perhaps! The diagram on AcuraPartsWarehouse seems to indicate that the location of the Transmission Range Sensor will be on the top side of the transmission, perhaps underneath the intake filter/breather housing. I think there's a write up on Acurazine on getting to it. However, if this is the true location of the Transmission Range Sensor throwing a PRNDL P0705, then I could not assert any specific cause to spills around the shifter in the cabin.
Any experience in disassembling the console to see if there's a sensor in the console attached to the shifter lever itself?
I have never disassembled the center console. I'm just theorizing it could be either the shifter contacts from the liquid spill, or the sensor itself, unrelated to any spillage.
Liquids will do all sorts of strange things to electronics. Sometimes, when the liquid dries out, everything goes back to normal. You may be looking at a temporary hiccup from a liquid spill. If you do get into the console, be sure to clean up everything, especially plugs, contacts and that sort of thing. That, along with clearing the code, may do it.
Did you spill any liquids around the shifter recently?
It is all mechanical, so I doubt liquids would have any effect. In any case, it looks like an easy job to replace the unit at the tranny if that is where the problem lies.
