2025 Honda Passport Service and Repair Manual

This factory service and repair manual for the 2025 Honda Passport covers a four-door sport utility built around a single powertrain: the 3.5L J35Y6 V6, a single-overhead-cam unit running naturally aspirated on gasoline, shared across the whole range. That consistency matters at the bench, because every engine specification, clearance and torque figure applies whichever of the three trims is in front of you, and what separates an EX-L from a TrailSport or a Black Edition sits in equipment and chassis hardware rather than under the hood.

Known issues on the 2025 Passport. Owners have filed 35 complaints against this model year so far, and they lean toward the electrical side: 12 concern the electrical system, five the engine and three the power train, with a further two on forward collision avoidance and one on the structure. Those are the areas this manual documents in most depth, through circuit diagrams, connector views and ground locations for tracing a fault back to its source, engine mechanical and driveline procedures, and the diagnostic sequences that confirm a repair against the original specification.
