About P0706

P0706 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0706 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0706 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This fault code is set when the Transmission Control Module (TCM) detects an issue with the signal from the transmission range sensor. The transmission range sensor, also known as the neutral safety switch, communicates the selected gear position to the TCM. The code is triggered when the TCM receives a signal from the range sensor that is outside of the expected parameters, indicating a performance or range issue. This can occur due to an incorrect signal being sent by the sensor, or if the sensor is not aligned properly with the mechanical position of the transmission.
