C0715 code meaning
Power Steering Pressure Sensor Range/Performance
What C0715 means
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.
C0715 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1 hours
- Clears after repairAfter a drive cycle
Symptoms of C0715
- Idle dips or engine stalls at full steering lock
- Idle stays raised while driving straight
Common causes of C0715
- Most likelyPressure sensor or switch stuck or drifting
- PossibleFluid seeping into the sensor connector
- Less likelyPump pressure abnormal due to low fluid or worn pump
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C0715 means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 15 | The exact fault in that area. |
What to do next
- Note C0715 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0715
What does C0715 mean?
C0715 means "Power Steering Pressure Sensor Range/Performance". C0715 is not traceable in public material; the publicly available J2012 tables, the NHTSA bulletin index and maker code lists all lack it. It is a generic code, so it means the same on every make.
Is it safe to drive with C0715?
C0715 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will C0715 fail an emissions test?
C0715 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0715 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C0715 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
