P0706: Transmission Range Sensor Circuit Range/Performance
Can you still drive? Drive with caution. The transmission may start in the wrong gear or shift erratically. If starting issues occur, try wiggling the shifter slightly in Park.
What Does P0706 Mean?
Code P0706 indicates that the transmission range sensor, also called the neutral safety switch or PRNDL sensor, is providing signals outside the expected range. This sensor tells the PCM which gear position the driver has selected. Incorrect readings can cause improper shift strategies and starting issues.

Frequently Asked Questions
What is the transmission range sensor?
The transmission range sensor tells the PCM which gear position (Park, Reverse, Neutral, Drive, etc.) the driver has selected, allowing it to control shift strategies and starter engagement.
Can a misadjusted shift cable cause P0706?
Yes, if the shift cable or linkage is stretched or misadjusted, the transmission range sensor may not align properly with the actual gear position, triggering P0706.
