2023-25 Duramax MAP Sensor Relocation

Protect your 2023½-2025 Duramax 6.6L’s manifold temperature and pressure sensors from dirty exhaust gas and sticky oil buildup with a Banks MAP Sensor Relocation Kit. A contaminated sensor can cause inaccurate readings, adversely affecting fuel economy and power output. The small billet aluminum device relocates the sensor out of the soot-filled exhaust stream.

Beginning in mid-2023, GM separated the MAP sensor into two sensors: a manifold temperature sensor located in the former MAP sensor position and a pressure sensor located in a new lower position. Duramax L5P sensor relocators are available individually or as a set.
