P0550 2003 INFINITI G35 Possible Causes
- Faulty Power Steering Pressure Sensor
- Power Steering Pressure Sensor harness is open or shorted
- Power Steering Pressure Sensor circuit poor electrical connection
Cost of diagnosing the P0550 2003 INFINITI G35 code
The cost of diagnosing the P0550 2003 INFINITI G35 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0550 2003 INFINITI G35 code detected?
An excessively low or high voltage from the Power Steering Pressure Sensor is sent to Engine Control Module (ECM).
P0550 2003 INFINITI G35 Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Power steering inoperative
P0550 2003 INFINITI G35 Meaning
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 Engine Control Module (ECM
). The ECM
controls the electric throttle control actuator and adjusts the throttle valve opening angle to increase the engine speed and adjusts the idle speed for the increased load.
