how to hook up a fuel level gauge, installation method of vehicle oil level sensor:
Intake air temperature sensor Installation: Intake manifold Use: Measuring intake air temperature Exhaust temperature sensor Installation: Three-way catalytic converter Application:
Measuring exhaust temperature and pressure sensor: There are intake manifold pressure, atmospheric pressure, combustion pressure, engine oil pressure, automatic transmission oil pressure, brake pressure
Dynamic pressure, various types of pump pressure, tire pressure. Speed sensor: crankshaft angle, crankshaft speed, steering wheel angle, wheel speed. speed acceleration
Sensors: vehicle speed (absolute value), acceleration.
Installation method of vehicle oil level sensor:
1. The air flow meter monitors the intake air volume and at the same time monitors the intake air temperature, adjusts the operation of the gasoline pump, and the throttle valve position sensor transmits the throttle valve position.
The sensor includes an idle speed motor and a throttle position potentiometer. Its function is to adjust the idle speed and reflect the throttle valve opening to adjust the fuel injection amount;
2. The role of intake pressure and air flow are similar. The role of camshaft position is used to monitor valve timing. This signal is used to correct the ignition advance angle. It can also start without it, but it is just a little shaking;
3. Variable timing valve adjustment The one on the five-valve chain is used to change the intake and exhaust timing water temperature monitoring engine water temperature adjustment at different speeds to save fuel injection, adjust the air conditioner switch to force the ignition off in an emergency.
fuel level sensor
1 - plug; 2. A cover plate; 3 - fuel level sensor 2; 4 - fuel level sensor 1; 55 - float of fuel level sensor 1; 6 - float of fuel level sensor 2
Test whether the resistance between terminal 5 of the ground circuit of the fuel level sensor and the ground is less than 5 Ω. If the specified range is exceeded, test the grounding circuit whether there is an open circuit or high resistance.Turn on the ignition and test whether the voltage between the terminal 5 of the grounding circuit of the fuel level sensor and the terminal 1 of the signal circuit of the fuel level sensor is within the specified voltage range; if it is lower than the specified range, test whether the voltage circuit of the fuel level sensor is short circuited to ground; If it is higher than the specified range, test whether the voltage circuit of fuel level sensor is short circuited to voltage; If the voltage circuit tests normal, replace the engine control module.
