How do I fix code P0551?
What repairs can fix the P0551 code?
- Scanning the vehicle, resetting the code, and testing to see if it comes back.
- Changing the power steering fluid.
- Replacing corroded wires or connectors.
- Repair or replace the power steering system.
- Repair or replace the power steering pressure sensor circuit.
What does engine code P0551 mean?
Error Code P0551 is defined as Power Steering Pressure Sensor Circuit Range/Performance, meaning its performance has been compromised or malfunctioning. This error code is a generic trouble code, meaning it applies to all vehicles equipped with the power steering pressure system.
What is the power steering pressure switch for?
Core Function. The power steering oil pressure switch works very much like the engine oil pressure switch. Their core function is to activate the warning light on the dashboard when oil pressure is low.
How do you test a power steering pressure sensor?
Power Steering Pressure Test
- With the engine stopped, install the pressure gauge with the shutoff valve in the open position.
- Start and idle the engine with the valve in the open position.
- With the gauge connected, close the shutoff valve for 5 seconds and compare it with the manufacturer’s specifications.
What causes code P0138?
Diagnostic trouble code (DTC) P0138 stands for O2 Sensor Circuit High Voltage (Bank 1, Sensor 2). The code will set when your car’s primary computer—also called the powertrain control module (PCM)—detects that, for a given period of time, the voltage signal from the rear O2 sensor is too high.
What does code P0451 mean?
What the P0451 code means. As fuel is stored in the vehicle’s fuel storage system, some of it will evaporate over time. When the P0451 code is set, it shows that the evaporative pressure sensor has detected pressure changes that are outside the accepted manufacturer specifications for the vehicle.
How do I know if my power steering pressure switch is bad?
Engine slowing down As soon as the power steering pressure switch starts to go bad, the computer will not be able to keep up with the demand of the power steering system and make proper adjustments. One symptom of this is the engine will slow down when you turn a corner, or while you are driving at low speeds.
How do you check a power steering pressure switch?
POWER STEERING PRESSURE SWITCH CHECK
- Disconnect the power steering oil pressure hose from the oil pump (Refer to ), and then connect following special tools.
- Bleed air, and then turn the steering wheel several times while the vehicle is not moving so that the temperature of the fluid rises to approximately 50 – 60°C.
What happens when a power steering pressure sensor goes bad?
Where is the power steering sensor located?
The power steering pressure switch is located either at the power steering pump or the gearbox.
How do you fix P0138?
What repairs can fix the P0138 code?
- Replacing the O2 sensor for bank 1 sensor 2.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
- Replacing the catalyst in front of the sensor.
- Repairing a leaking injector.
Which 02 sensor is bank 1 sensor 2?
Therefore, in an in-line 4-cylinder engine, the term “Bank 1, Sensor 1” simply refers to the front oxygen sensor. “Bank 1, Sensor 2” is the rear oxygen sensor.
