This bulletin applies to 2013-2021 Mazda CX-5, 2014-2021 Mazda 6, 2014-2018 Mazda 3, 2016-2021 CX3, MX-5 and CX-9 vehicles. Some vehicles may experience the check engine light on with DTC P2610 and P2507 stored in memory after engine start and with room fuse 15A removed.

As a past malfunction, no warning light may be on but the DTC may be found during service. P2507 in this situation is only applicable to 2016 and later models. This is caused by the engine being started 3 or more times after a short duration of engine off (less than 15 seconds) with the room fuse removed.

Verify DTC P2610 and P2507 are stored in PCM memory. Install room fuse 15A with ignition off. Start the engine and let it run for at least 10 seconds, then stop the engine. Start the engine again and verify that the check engine light is off, then stop the engine. Clear DTCs using IDS.
