About P117A

P117A is a manufacturer-specific powertrain diagnostic trouble code recorded for Mazda vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

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.

P117A 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

P117A is set by the PCM on Mazda SkyActiv G and SkyActiv D engines when measured or modelled engine oil temperature rises above the threshold at which piston protection becomes necessary. The PCM monitors oil temperature continuously and, once that limit is exceeded, applies a torque restriction so combustion pressure and piston crown temperature are brought back under control. The code is therefore a record that the protection strategy has operated, rather than a direct statement that one component has failed. Members most often meet it on a CX 5, Mazda 3 or Mazda 6 presenting with a sudden l...
