WARNING
The power steering system is designed to provide power assist while driving to operate the steering wheel with light force.
When the steering wheel is operated repeatedly or continuously while parking or driving at a very low speed, the power assist for the steering wheel will be reduced. This is to prevent overheating of the power steering system and protect it from getting damaged. While the power assist is reduced, steering wheel operation will become heavy. If the steering wheel operation is still performed, the power steering may stop and the power steering warning light will illuminate. In a safe location, stop the engine and push the ignition switch to the OFF position. The temperature of the power steering system will go down after a period of time and the power assist level will return to normal after starting the engine. The power steering warning light will go off. Avoid repeating such steering wheel operations that could cause the power steering system to overheat.
You may hear a noise from the front of the vehicle when the steering wheel is operated. This is a normal operational noise and is not a malfunction.
If the electric power steering warning light illuminates while the engine is running, it may indicate the power steering system is not functioning properly and may need servicing. Have the power steering system checked. It is recommended that you visit a NISSAN dealer for this service.
When the electric power steering warning light illuminates with the engine running, there will be no power assist for the steering but you will still have control of the vehicle. At this time, greater steering effort is required to operate the steering wheel, especially in sharp turns and at low speeds.

WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur
from high pressure
coolant escaping from the radiator. Wrap a thick cloth around the radiator cap.
Slowly turn it a quarter

P0550 PSP sensor
Description
Power steering pressure (PSP) sensor is installed to the power steering
high-pressure tube and detects a
power steering load.
This sensor is a potentiometer which transforms the power steering load into
output voltage, and emits the
voltage signal to the ECM. The ECM controls ...
