P0705: Transmission Range Sensor Circuit Malfunction (PRNDL Input)
7 vehicles · 4 makes · $120-$9,000 repair
Most Reported On
P0705 is an OBD-II diagnostic trouble code meaning “Transmission Range Sensor Circuit Malfunction (PRNDL Input).” The transmission range sensor (also called the neutral safety switch or PRNDL switch) tells the computer which gear position the shifter is in (Park, Reverse, Neutral, Drive). P0705 sets when the signal from this sensor is missing, out of range, or inconsistent. Symptoms include no-start in Park, the wrong gear indicator on the dash, harsh or incorrect shifts, and sometimes the engine starting in any gear position. This code is most commonly reported on 2015 Chrysler 200, 2021-2023 Subaru Outback, and 2022 Subaru Forester, plus 4 other vehicles, with repair costs ranging from $120 to $9,000.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
