P1307 — Chassis Acceleration Sensor Signal Malfunction

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Kia

About P1307

P1307 is a manufacturer-specific powertrain diagnostic trouble code recorded for Kia vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1307 is stored, the module has detected 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.

P1307 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The chassis acceleration sensor, often called a G sensor, measures vehicle acceleration forces and reports them as a voltage signal to the control module that manages systems such as all wheel drive torque distribution or vehicle stability. DTC P1307 sets when the module detects the acceleration sensor signal is implausible, out of range, or not changing in a way that agrees with other motion data such as wheel speed. The sensor is typically supplied with a reference voltage and a ground and returns a signal that sits near a mid point at rest and swings with acceleration and braking. Causes in...
