fuel gauge tank float level sending unit for Honda accord
1. Throttle position sensor,fuel gauge tank float level sending unit for Honda accord:
Function: the throttle position sensor is used to monitor the throttle opening angle, determine the idle speed, full load, acceleration and deceleration conditions, and implement the throttle opening status.Corresponding various fuel injection quantity control. Effect of failure: the idle speed changes from high to low, or causes flying.
2. Intake valve pressure sensor
Function: the intake pressure sensor is used to provide engine load information, namely.In case of pressure measurement of the intake pipe, the intake air quantity into the engine is indirectly measured, and then the intake air quantity is converted into an electrical signal through the internal circuit and provided to the computer. Failure effect: the engine is not easy to start or the idle speed is unstable.
3. Intake air temperature sensor
Function: provide air temperature information for correcting fuel injection quantity and ignition timing. Failure effect: low idle speed, easy to shut down.
4. Crankshaft angle sensor
Function: to provide rotation speed and crankshaft phase information, and provide reference points for injection timing and ignition timing. Failure effect: the engine cannot be started or the engine suddenly stops after starting.
5. Coolant temperature sensor
Function: it monitors the engine coolant temperature, converts it into a voltage signal and sends it to the computer. The ECU controls the fuel injection quantity, ignition timing and idle speed according to this signal. Failure effect: low idle speed.
6. Oxygen sensor
Function: it is the main element to provide mixer concentration information, which is used to correct fuel injection quantity, realize closed-loop control of air-fuel ratio, and ensure that the actual air-fuel ratio of the engine is close to the theoretical air-fuel ratio. Failure effect: unstable idle speed and excessive consumption.
7. Knock sensor
Function: to provide knock information for correcting ignition timing and implementing knock closed-loop control. Failure effect: when the knock signal point cannot be provided before the knock is about to occur, the "peak" of the signal that the computer cannot receive cannot reduce the ignition advance angle, and knock occurs.
8. Three way catalyst
Function: the three-way catalyst is installed in front of the muffler in the exhaust pipe, It can simultaneously reduce three pollutants in the exhaust gas (the conversion efficiency of the three-way catalyst is the highest when the content of carbon monoxide (CO), unburned carbon oxides (HC) and oxides (NOx) and the air-fuel ratio of the engine are close to the theoretical air-fuel ratio.
