How to solve the fault code p 165 1?

Fault code: P 165 1

English: Power Steering Pressure Switch-Input Fault

Power steering pressure switch-input fault.

Category: power system

The power steering pressure switch is used to increase the idle speed of the engine and turn off the air compressor when the electronic control unit detects that the load pressure of the power steering system is too high to prevent the engine from stalling. The reasons include steering wheel not turning during self-inspection, PSP switch/short circuit rod failure, PSP signal circuit open or short circuit to ground, PSP switch ground circuit open, electronic control module failure, etc.

2. Applicable models of fault codes: GM, Buick, Chevrolet, Cadillac, Hummer and Jinbei.

Fault code: P 165 1

Engine cooling fan motor relay 1- circuit fault.

Engine cooling blower motor relay 1- circuit fault.

Category: power system

Details: When the coolant temperature reaches a set value, the PCM will start the coolant fan to help reduce the temperature. Causes include cooling fan relay itself or its circuit failure, electronic control module failure, etc.

5. Fault code applicable model: Volvo

Fault code: P 165 1

Maximum torque exceeded-fuel cut-off initiated

Maximum torque exceeded-fuel cut-off initiated.

Category: power system

The power steering pressure switch is used to increase the idle speed of the engine and turn off the air compressor when the electronic control unit detects that the load pressure of the power steering system is too high to prevent the engine from stalling. The reasons include steering wheel not turning during self-inspection, PSP switch/short circuit rod failure, PSP signal circuit open or short circuit to ground, PSP switch ground circuit open, electronic control module failure, etc.

6. Fault code applicable model: Volvo

Fault code: P 165 1

Air Flow Sensor/Manifold Absolute Pressure Sensor-Incredible signal related to throttle position

Mass air flow sensor/manifold absolute pressure sensor-implicit signal with throttle position

Category: power system

Details: The function of the air flow sensor is to convert the air flow into an electrical signal and send it to the electronic control unit as one of the basic signals to determine the fuel injection quantity. The manifold absolute pressure sensor is used to measure the pressure in the intake manifold. Then, PCM will use the difference between intake manifold pressure and atmospheric pressure as the basis to determine the basic fuel injection quantity of the injector, so as to help the engine obtain the best air-fuel ratio under different loads.

7. Fault code applicable model: Jaguar

Fault code: P 165 1

Power steering pressure switch-input signal

Power steering pressure switch-input signal

Category: power system

The power steering pressure switch is used to increase the idle speed of the engine and turn off the air compressor when the electronic control unit detects that the load pressure of the power steering system is too high to prevent the engine from stalling.

8. Fault codes are applicable to models: Audi and Volkswagen.

Fault code: P 165 1

Controller LAN data connection, power system-no signal

CAN data bus, power system-no signal

Category: power system

Detailed meaning: Controller area network is an automobile communication protocol, which is characterized by allowing devices on the network to communicate with each other directly without the host computer controlling the communication on the network. @20 19
