- Generic OBD-II code · Powertrain
- Turns on the check-engine light

- How the car detects it
- P25E6 tells that on bank 2 the exhaust cam phaser has not left its locked angle despite a command to adjust. The module then has one exhaust camshaft that can no longer be phased, which shifts valve overlap on that bank and can upset idle quality and the emissions balance between the two banks. Ford's 2014 list for the Boss 302S V8 includes P25E6 as a lamp code, together with the matching intake and bank 1 codes. The root causes resemble those of the other stuck-lock codes but should be checked on the bank 2 side specifically: oil feed and screen to that head, the bank 2 exhaust control valve and the phaser itself. CARB obliges OBD systems to flag VVT systems that do not reach their target angle. Expect the warning lamp, reduced power and possibly a rattle from the timing drive.
