C0715Power Steering Pressure Sensor Range/Performance
- Generic OBD-II code · Chassis
- Needs a drive cycle to confirm a fix
- How the car detects it
- C0715 is not traceable in public material; the publicly available J2012 tables, the NHTSA bulletin index and maker code lists all lack it. The function it names is well known from engine diagnostics, where the same check runs as P0551. On hydraulic steering the pump pressure rises with steering effort and a switch or sensor tells the engine controller to raise idle. Mitsubishi flags the circuit when the switch stays on after a stop that follows at least 4 s above 50 km/h; Saab sets P0551 on the 9-3 when the switch state changes for 600 s above 50 km/h and keeps the higher idle meanwhile. Toyota replaced the sensor on the 2007-08 Tundra to cure circuit low and high codes. Typical results are stalling or dipping idle at full lock, or a raised idle when driving straight.
