Fault code P 140 1

1. Fault code applicable model: Mercedes-Benz fault code: P 140 1 English meaning: EGR position sensor English meaning: Category: powertrain system (from the manufacturer's own meaning) Detailed meaning: The function of EGR system is to introduce a small amount of exhaust gas into the intake manifold when the engine is running at high load. The existence of these exhaust gases reduces the temperature and pressure of the combustion chamber, thus reducing the emission of nitrogen oxide pollutants. 2. Fault code applicable models: Toyota and Lexus fault code: P 140 1 Chinese meaning: throttle position (TP) sensor 2- range/performance English meaning: throttle position sensor 2- range/performance category: powertrain system (from the manufacturer's own meaning) Detailed meaning: throttle valve, commonly known as throttle valve, is used to control engine intake and exhaust. 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. The reasons include the failure of the throttle position (TP) sensor itself or its circuit, and the failure of the electronic control module (ECM or PCM). 3.2 applicable vehicle type of fault code: Mazda fault code: P 140 1 Chinese meaning: differential pressure feedback sensor-high voltage detected English meaning: differential pressure feedback sensor-high voltage detected category: powertrain system (manufacturer's own meaning) Detailed meaning: the function of exhaust gas recirculation (EGR) system is to introduce a small amount of exhaust gas into the intake manifold when the engine is running at high load. If the signal voltage of DPFE(EGR Differential Pressure Feedback) sensor is higher than 4.5V, this fault code will appear. The reasons include short circuit of positive pole of signal circuit of DPFE(EGR pressure difference feedback) sensor, fault of DPFE sensor, fault of electronic control module (PCM or ECM), etc. 4. 1 fault code applicable model: land rover fault code: P 140 1 Chinese meaning: exhaust pressure sensor-high voltage English meaning: exhaust pressure sensor-high voltage category: power system (meaning from manufacturer) Detailed meaning: 5.0 fault code applicable model: Saab(9-2X) fault. Fuel Tank Pressure Control System-Fault Type: Power System (The existence of these exhaust gases reduces the temperature and pressure of the combustion chamber, thus reducing the emission of nitrogen oxide pollutants. If the signal voltage of DPFE(EGR Differential Pressure Feedback) sensor is higher than 4.5V, this fault code will appear. The reasons include short circuit of positive pole of signal circuit of DPFE(EGR pressure difference feedback) sensor, fault of DPFE sensor, fault of electronic control module (PCM or ECM), etc. 6. Applicable models of fault codes: Ford, Mercury and Lincoln. Fault code: P 140 1 Chinese meaning: EGR pressure sensor-high input English meaning: EGR pressure sensor-high input category: powertrain system (from the manufacturer's own meaning) Detailed meaning: the function of EGR system is high. If the signal voltage of DPFE(EGR Differential Pressure Feedback) sensor is higher than 4.5V, this fault code will appear. The reasons include short circuit of positive pole of signal circuit of DPFE(EGR pressure difference feedback) sensor, fault of DPFE sensor, fault of electronic control module (PCM or ECM), etc. 7. Fault code applicable vehicle type: modern fault code: P 140 1 Chinese meaning: fuel tank leakage diagnosis module-system fault English meaning: fuel tank leakage diagnosis module-system fault category: power system (meaning from manufacturer) Detailed meaning: The function of the leakage diagnosis module is to apply the leak detection pump (LDP) to the evaporative emission (EVAP) system. 8. Fault code applicable vehicle type: Volvo fault code: P 140 1 Chinese meaning: engine control module (ECM)- fault English meaning: engine control module (ECM)- fault category: power system (meaning from manufacturer) Detailed meaning: 9. Applicable model of fault code: Subaru fault code: P 140 1 Chinese meaning: fuel tank pressure control system-fault English meaning: fuel tank pressure control system-fault category: powertrain system (from the manufacturer's own detailed meaning: engine control module, also known as engine control unit (some on-board engine control modules and transmission control modules are integrated into the powertrain control module), which controls the operation of the whole engine. Its main function is to control the optimal fuel injection quantity and ignition timing of the engine. Another important function is to monitor the components of exhaust emission control. 10. Fault code applicable vehicle type: Jaguar fault code: P 140 1 English meaning: EGR solenoid valve-position control English meaning: EGR solenoid valve-position control category: powertrain system (from the manufacturer's own meaning) Detailed meaning: EGR system is used to control the engine to run at high speed, and the existence of these exhaust gases reduces the temperature and pressure of the combustion chamber. 1. Vehicle type to which the fault code applies: Nissan, finidi, UK. Fault code: P 140 1 English meaning: EGR temperature sensor-circuit fault English meaning: EGR temperature sensor-circuit fault category: powertrain system (from the manufacturer's own meaning) Detailed meaning: EGR system. 12. The fault code is applicable to Audi. Common fault code: P 140 1 Chinese meaning: EGR valve/solenoid valve-short circuit to ground (row 65438) English meaning: EGR valve/solenoid valve-short circuit to ground (row 65438).
