Mazda Vehicles Experience Stuck Codes

Order Reprints

Some 2019 Mazda CX-3, CX-5, MX-5 and Mazda3 vehicles may experience the check engine light on with DTCs P2096:00 (air fuel too lean), P2097:00 (air fuel too rich) and/or P0524:00 (engine oil pressure too low) in the PCM memory that cannot be cleared, and the check engine light stays on even if the detection is gone.  

The concern may be caused by improper PCM control logic. The PCM software has been modified to eliminate this concern.  Reprogram to the latest software version.
