P0551 - Power Steering Pressure Sensor Circuit Range/Performance

The Technical Definition: The sensor's signal is irrational or not changing during a turn.

Common Symptoms: The engine may die when turning the wheel while parking, steering can become heavy or difficult, and the engine might develop an erratic or rough idle.

Typical Fix: Start by checking the power steering fluid levels. The most common repair is replacing the power steering pressure sensor, but you should also inspect the sensor and wiring for fluid leaks or damage.
