I had a CEL light come on in my 98 milly & decided to get a full diagnostic on it. It pulled a code P0705 for a range sensor. Of course, the dealership wants an arm & a leg to replace it, so I want to replace it on my own. Unfortunately, no auto places seem to know what a range sensor is & I can't find anything really relevant in google searches either. Anyone know if this has another name or where I can get one? Thanks.

This is the circuit that tells the computer what range (PRNDL) the transmission is in.

any idea on where to get one? I found out the full name is like "transmission range sensor circuit (PRNDL Inp.)" but can't find anyone with this either. Is this something I can even replace myself. If it is actually circuitry, I am not gonna mess with it. Sounded like just a sensor. Is the thing even necessary, or does it just do something like let the car go into gear when it is not started? Or is it a bit more important like it won't drive when it is in "D"? Thanks.

The circuit consists of the transmission range switch that is attached to the transaxle and the wiring harness and connectors between the switch and the ECU. The problem could be as simple as a bad switch or a connector that needs to be cleaned.

I looked in the tech manual for this, but they don't call it the same thing on my 2000. What the book does say is that there's a "tranmission range switch", "in center rear of engine compartment, on transaxle" on the 2.3L engine and "in left front of engine compartment, on transaxle" of the 2.5L engine.

I would try and find it, take apart the connector, clean everything up, and put it back together.

Hi,try asking for an inhibitor switch.This is located on the transmission where the shift cable is attached.It tells the PCM what gear has been selected.Also it does not allow starting in any gear but P or N.Common symptoms would be a no start in Park,or when accellerating it feels like it starts in 3rd gear.

Thanks for the replies. I will give a shot at cleaning it. I had a couple issues actually when I took it in. The transmission seemed kinda jumpy at times, so that might be the problem I am guessing. Also pulled a knock sensor code, which I am replacing. I still am not finding anything on the inhibotor switch or tranmission range switch either. Is this by chance the same thing as a park-neutral switch? This is the term I have always heard & can find these for the milly, but not sure if it is the same thing.
