Fault code P 1 1 18

1. Fault code applicable vehicle type: modern fault code: p118 Chinese meaning: electronic throttle system, throttle motor-fault English meaning: electronic throttle system, throttle motor-fault category: powertrain system (manufacturer's own meaning) Detailed meaning: in electronic throttle control (ETC) 2. The fault code is applicable to the vehicle model: Volvo fault code: p118 Chinese meaning: manifold absolute pressure (MAP) sensor /MAF sensor, adaptability/performance problem, lower limit English meaning: manifold absolute pressure sensor/mass air flow sensor, adaptability/performance problem, Lowe category: power system (manufacturer's meaning) The power system control module (PCM) will then determine the basic fuel injection quantity of the fuel injector according to the difference between the intake manifold pressure and the atmospheric pressure (which has a linear relationship with the engine load), so the function of the MAF sensor is to convert the air flow into an electrical signal and send it to the electronic control unit (ECU) as one of the basic signals for determining the fuel injection quantity. 3. The fault code is applicable to the vehicle model: BMW fault code: p118 Chinese meaning: MAF sensor-high input (second row) English meaning: mass air flow sensor-high input (second row) Category: powertrain system (from the manufacturer's own meaning) Detailed meaning: MAF sensor is used to put the. 4. The fault code is applicable to models: Audi and Volkswagen. The fault code is p 1 1 8. Chinese meaning: heater circuit of heated oxygen sensor is open (row 65438 +0, sensor 2). English meaning: heater circuit of heated oxygen sensor is open (row 65438 +0, sensor 2). No matter which row, the first sensor always refers to the upstream oxygen sensor (in front of the catalytic box), and the second sensor always refers to the downstream oxygen sensor (behind the catalytic box). Causes include heater circuit of oxygen sensor, connector failure, failure of oxygen sensor itself, failure of electronic control module (PCM or ECM), etc. 5. Fault code applicable models: Toyota and Lexus. Fault code: P118 Chinese meaning: coolant temperature sensor of coolant heat storage tank system-circuit low English meaning: coolant temperature sensor of coolant heat storage tank-circuit high category: power system (meaning from manufacturer) Detailed meaning: hybrid vehicles have coolant heat storage tank (CHS). Before the engine needs to be started, the electronic control unit (ECU) will start the water pump, deliver hot coolant to the engine and preheat the cylinder head. This can prevent the air-fuel ratio from being too rich during cold start, thus saving fuel. This fault code indicates that the coolant temperature sensor circuit at the outlet of the coolant hot storage tank is open. The reasons include the coolant temperature sensor at the outlet of the coolant heat storage tank, the sensor circuit open circuit, ECU, etc. 6. Fault code applicable model: Land Rover fault code: p118 Chinese meaning: radiator outlet engine coolant temperature-high input English meaning: radiator outlet engine coolant temperature-high input category: powertrain system (meaning from manufacturer) Detailed meaning: engine coolant temperature (ECT) sensor uses the principle of thermistor, Convert the engine coolant temperature into an electrical signal. 7. The fault code is applicable to the vehicle model: KIA fault code: p118 Chinese meaning: electronic throttle system, throttle motor-fault English meaning: electronic throttle system, throttle motor-fault category: power system (from the manufacturer's own meaning) Detailed meaning: in electronic throttle (ETC) The throttle actuator is a stepping motor, which is responsible for controlling the throttle opening according to the instruction of the throttle control module.
