1. Throttle Position Flow Sensor Abbreviation: TPS 2. Camshaft Position Sensor Abbreviation: CMPS Functions and Fault Symptoms of Each Sensor 1 At present, there are mainly two types of air flow sensors: hot wire air flow sensors and hot film air flow sensors, which are generally installed between the air filter and the throttle valve. Function: Measure the intake volume of the engine and input the signal into the ECU as the main control signal for fuel injection and ignition control. Fault mode: After the malfunction of the air flow sensor, the cars electronic control unit (ECU) cannot detect the true intake air volume, resulting in an imbalance of the mixture, leading to unstable engine idle, weak driving, black smoke, and sometimes shifting gears and stalling. 2. The intake pressure sensor, abbreviated as MAP, is installed on the intake manifold and is usually integrated with the intake temperature sensor. Function: Detect the absolute pressure of the intake manifold, then convert it into a voltage signal and send it to the ECU. The ECU controls the basic fuel injection quantity based on the voltage of this signal. Fault mode: Una
3、 The throttle position sensor includes switch contact type throttle position sensor, linear variable resistance throttle position sensor, and comprehensive throttle position sensor. The throttle position sensor is installed on the throttle valve to detect the opening of the throttle valve. Function: The main function of the throttle sensor is to provide feedback on the opening of the throttle valve, thereby controlling the fuel injection amount during acceleration. Fault mode: Abnormal idle operation of the engine (such as too high or too low idle, unstable idle, easy stalling at idle) or abnormal acceleration of the engine (engine shaking during acceleration, delayed acceleration response, etc.), sometimes leading to intermittent shaking of the engine during operation.
4、 The camshaft position sensor is used to detect the angular position of the camshaft, and the engine control module (ECU) uses this signal to determine the cylinder sequence of the engine. Function: Detect the position of the camshaft, determine the top dead center of the compression stroke of cylinder one, control the sequence of fuel injection and ignition. Fault mode: When the camshaft position sensor fails, the output power of the engine will decrease. There may be issues such as ineffective ignition, difficulty in closing the fuel door, shaking of the car, constant malfunction lights, and stalling when the car is hot.
