Fault code P 1263

1. applicable vehicle failure code: Saab (except 9-2x) failure code: P 1263 Chinese meaning: throttle valve-manual movement when engine is running English meaning: throttle valve-manual movement when engine is running Category: power system (meaning from manufacturer) Detailed meaning: throttle valve, commonly known as throttle valve, is a controllable valve used to control engine intake. In the electronic throttle (ETC) system, the electronic control module (ECU) instructs the throttle position motor to optimize the throttle opening according to the signal from the accelerator pedal position (APP) sensor, engine speed, vehicle speed, air conditioning energy consumption, etc. 2. Applicable models of fault codes: Ford, Mercury and Lincoln. Fault code: P 1263 Chinese meaning: fuel injector circuit, cylinder 3-open circuit/short circuit to ground English meaning: fuel injector circuit, cylinder 3-open circuit/short circuit to ground category: power system (from the manufacturer's own meaning) Detailed meaning: the function of fuel injector is to atomize fuel to meet the requirements of combustion. The working principle is that when the electromagnetic coil is energized, it generates suction, the needle valve is sucked up, the nozzle is opened, and the fuel is ejected at high speed through the annular gap between the needle and the nozzle, forming a fog. The ECU controls the fuel injection quantity by controlling the opening time interval (also called pulse width) of the fuel injector. 3. Fault codes are applicable to the following vehicles: Nissan, finidi and UK. Fault code: P 1263 Chinese meaning: turbocharger supercharging control-performance (second row) English meaning: turbocharger supercharging control-performance (second row) Category: powertrain system (from the manufacturer's own meaning) Detailed meaning: turbocharger uses the inertia impulse of exhaust gas from the engine to push the turbine, and then drives the coaxial impeller to center. The function of the turbo/supercharger boost controller is that when the boost pressure reaches the set value, the air pressure pushes the wastegate actuator (pneumatic-mechanical) to bypass the turbine, thus reducing the turbine speed and controlling the boost level. 4. Fault code applicable vehicle type: Audi and Volkswagen fault code: P 1263 Chinese meaning: Fuel injector signal is not credible -2 cylinder English meaning: Fuel injector implicit signal -2 cylinder category: power system (from the manufacturer's own meaning) Detailed meaning: The function of fuel injector is to atomize fuel to meet the requirements of combustion. The working principle is that when the electromagnetic coil is energized, it generates suction, the needle valve is sucked up, the nozzle is opened, and the fuel is ejected at high speed through the annular gap between the needle and the nozzle, forming a fog. The ECU controls the fuel injection quantity by controlling the opening time interval (also called pulse width) of the fuel injector.
