Gasoline Engine Air-fuel (A/F) Ratio Sensor
As with the oxygen sensor, the air-fuel ratio sensor detects the oxygen concentration in the exhaust gas. Conventional oxygen sensors are such that the output voltage tends to change drastically at the Read more Gasoline Engine Air-fuel (A/F) Ratio Sensor
Gasoline Engine Oxygen Sensor (O2 Sensor)
To maximum the exhaust purification function of the engine with TWC (Three-Way Catalytic Converter), the air-fuel ratio must be kept within a narrow range around the theoretical air-fuel ratio. The oxygen Read more Gasoline Engine Oxygen Sensor (O2 Sensor)
Gasoline Engine Water Temperature Sensor/ Intake Air Temperature Sensor
The water temperature sensor and intake air temperature sensor have builtin thermistors for which the lower the temperature, the larger the resistance value and, conversely, the higher the temperature, Read more Gasoline Engine Water Temperature Sensor/ Intake Air Temperature Sensor
Throttle Position Sensor
The throttle position sensor is installed on the throttle body. The sensor converts the throttle opening angle to voltage, which is sent to the engine ECU as the throttle opening signal (VTA). In addition, Read more Throttle Position Sensor
Manifold Pressure Sensor (Vacuum Sensor)
The manifold pressure sensor is used with D-type EFI for sensing the intake manifold pressure. This is one of the most important sensors in D-type EFI. By means of an IC built into this sensor, the manifold Read more Manifold Pressure Sensor (Vacuum Sensor)
What is Sensors/Switches?
The sensors/switches play the role of collecting the types of data used to determine the various controls, and convert them into electrical signals, which are then transmitted to the Engine & ECT ECU. Read more What is Sensors/Switches?
