Diagnostic trouble code (DTC) P2646 points to slightly different things on different Honda vehicles, including the 2007 Odyssey -- "Rocker arm oil pressure switch circuit low voltage" on the J35A6 engine, or "VTEC system stuck off" on the J35A7 engine. In laymen's terms, these mean that there's an issue with the either the VTEC or rocker arm's oil pressure switch and their respective communication with the rest of the vehicle. Depending on Your trim level, the code will mean different things. The Touring trim has the J35A7 engine, whereas the J35A6 is found on the lower trims. Therefore, the fix is largely dependent on Your configuration. A helpful firSTStep is to check the engine oil level, as this can set the code regardless of equipped engine.

The 2007 honda odyssey code means vtec system stuck off. That code can be caused by a bad oil pressure sensor, bad vtec solenoid, or plugged oil passages.
