P26C3Internal Control Module Transmission Range Sensor Performance
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P26C3 comes from a second, independent checking layer inside the powertrain module: it recalculates the gear selector position (P-R-N-D) and logs a fault when it cannot confirm what the main signal path reports. Ford lists the code in its gasoline OBD summaries 2020–2024 as non-MIL; the 2024 edition splits it into sub-faults for range sensor A, range sensor B and the comparison of both. Ford special service message 47790 names P26C3 among the most frequent codes on 2013–2019 Fusion, MKZ and C-Max with the 2.0 L hybrid drive, caused by water or corrosion in several connectors. Faults in the sensor circuits themselves are covered by P0705, P2800 and P2805. Drivers usually notice a warning message or trouble selecting a gear.
