P0706: Transmission Range Sensor A Circuit Range/Performance

What does P0706 mean?

The range sensor A reading is implausible for the selected gear. The circuit may produce a signal, but the controller cannot reconcile it with the expected selector position.

Generic OBD-II definition: Transmission Range Sensor A Circuit Range/Performance. Confirm applicability in your vehicle service information.

Common causes

• Misadjusted range sensor or linkage
• Worn range switch
• Open or shorted range wiring

Symptoms

• Wrong gear indication
• Delayed engagement
• No-start or limp mode

Diagnostic focus

Check adjustment before replacing the sensor. A mechanically misaligned switch can pass an electrical continuity check in one position and still report the wrong range.

Can I keep driving with P0706?

Severity: High Keep the vehicle secured and do not drive if the selected gear, displayed gear, or starting interlock is unreliable. Arrange diagnosis rather than bypassing the range/neutral-safety system.

If the check engine light is flashing or the car runs badly, stop driving and have it checked.

Typical fixes

• Confirm selector cable and sensor alignment
• Watch range data through each position while secured
• Test the switch pattern to the transmission-specific chart
