Fault code P 1545

1. Fault code applicable models: GM, Buick, Chevrolet, Cadillac, Hummer, Jinbei Fault code: P 1545 Chinese meaning: air conditioning compressor clutch relay-low voltage English meaning: air conditioning compressor clutch relay-low voltage category: powertrain system (from the manufacturer's own meaning) Detailed meaning: when the air conditioner is turned off, the pulley of the air conditioner just idles. When there is only air-conditioning clutch (low voltage category), the reasons include the failure of air-conditioning compressor clutch coil, the failure of air-conditioning clutch relay or its control circuit, and the failure of electronic control module (PCM or ECM). 2. Fault code applicable vehicle type: mini fault code: P 1545 Chinese meaning: TP sensor 1- incredible signal English meaning: TP sensor 1- hidden signal category: powertrain system (from the manufacturer's own meaning) Detailed meaning: throttle valve, commonly known as throttle valve, is a controllable valve used to control engine intake. The throttle position (TP) sensor is used to send the throttle opening to the electronic control unit (ECU) in the form of electrical signal, which is one of the basic parameters for controlling the fuel injection of the engine. 3. Fault code applicable vehicle type: Audi and Volkswagen fault code: P 1545 Chinese meaning: throttle control-fault English meaning: throttle control-fault category: powertrain system (from the manufacturer's own meaning) Detailed meaning: throttle, commonly known as throttle, is a controllable valve used to control the intake of the engine. The reasons include dirty carbon deposit on the throttle body, the throttle not in the fully closed position, the failure of the throttle position actuator or its circuit or connector, the failure of the throttle control module, the dislocation of the accelerator pedal and the failure of the electronic control module (PCM or ECM). 4. Fault code applicable model: Isuzu fault code: P 1545 Chinese meaning: air-conditioning compressor clutch relay-circuit fault English meaning: air-conditioning compressor clutch relay-circuit fault category: power system (meaning from the manufacturer) Detailed meaning: 5. Fault code applicable model: Mitsubishi, long fault code: P 1545 Chinese meaning: engine temperature-radiator outlet signal change English meaning: radiator outlet engine temperature-signal change category: powertrain system (from the manufacturer's own meaning) Detailed meaning: the pulley of the air conditioner only idles when the air conditioner is turned off, and only when the air conditioner clutch (under the action of solenoid valve) is engaged will it drive the compressor to run. The function of air-conditioning clutch relay is to control the separation and combination of clutch. Causes include air-conditioning clutch signal circuit fault, air-conditioning clutch power supply circuit fault, air-conditioning compressor relay fault, powertrain control module (PCM) fault, etc.
