How to match the new Mondeo tire pressure sensor

1, throttle position sensor?

Function: The throttle position sensor monitors the throttle opening and determines the idle speed, full load and acceleration and deceleration, so as to implement the throttle opening state.

Various corresponding fuel injection quantity control. Fault impact: the idle speed is high and low, or the overspeed phenomenon is caused. ?

2. Intake valve pressure sensor?

Function: The intake pressure sensor provides engine load information, that is, it is connected with the engine.

When measuring the pressure of the intake pipe, the intake air quantity entering 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. Fault effect: the engine is not easy to start, or the idle speed is unstable. ?

3. Air temperature sensor?

Function: Provide air temperature information to correct fuel injection quantity and ignition timing. ? Fault effect: low idle speed and easy flameout. ?

4. Crankshaft angle sensor?

Function: Provide information of speed and crankshaft phase, and provide reference points for fuel injection timing and ignition timing. Fault effect: the engine can't start or the engine suddenly shuts down after starting. ?

5. Coolant temperature sensor?

Function: Monitor the temperature of engine coolant, convert it into voltage signal and send it to computer. ECU controls fuel injection, ignition timing and idle speed control according to this signal. ? Fault effect: low idle speed. ?

6. oxygen sensor?

Function: Provide mixer concentration information, 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 impact: unstable idle speed and excessive consumption. ?

7. Knock sensor?

Function: To provide knock information for correcting ignition timing and realizing knock closed-loop control. ? Fault influence: When knocking is about to happen, it is impossible to provide the knock signal point, the computer can't receive the signal "peak", and the ignition advance angle can't be reduced, thus knocking occurs. ?

8. Three-way catalyst?

Function: the three-way catalytic converter is installed in front of the muffler in the exhaust pipe, which can simultaneously reduce the contents of three pollutants (carbon monoxide co, unburned carbon oxide HC and oxide Nox) in the exhaust gas. When the air-fuel ratio of the engine approaches the theoretical air-fuel ratio, the conversion efficiency of the three-way catalytic converter is the highest. When the high temperature of 300℃ ~ 800℃ passes through the center of the three-way catalyst, the harmful gas is oxidized and reduced by the expensive catalyst attached to the ceramic monomer and converted into harmless gas. ? Failure impact: Exhaust gas can't reach the standard.
