Transmission range sensor circuit
What P0705 means
Your car's computer set P0705: Transmission range sensor circuit. It belongs to the transmission group of codes. It is a generic code, so it means the same thing on every make. The check engine light usually comes on once the fault has been seen on two drives in a row. Until then it shows up as a pending code.
Can I keep driving? The car may not start in Park or may shift oddly. Get it checked.
Common causes
- Misadjusted or failed transmission range sensor
- Wiring or connector problem
Fix the cheapest, most likely cause first. Clearing the code without a repair only turns the light off until the fault comes back.
Check it yourself
Check whether the car starts in Neutral and in Park.
