...Technical Information Coolant temperature sensor General The coolant temperature sensor provides information for air/fuel mixture preparation by recording the operating temperature of the engine. The ECU adapts the injection time and the ignition angle to the operating conditi...
...Technical Information Crankshaft Sensor General Crankshaft sensors record the engine speed and crankshaft position. The fitting position is near the flywheel ring gear. More they are found on the engine block with the sensor ring bolted onto the crankshaft There are two differen...
...Technical Information Idle speed control valve General The idle speed control valve is bypass valve. Example, as shown, is for Opel. It is made of a cast housing with a magnetic valve servo unit. A jet stem is fitted to the servo unit. Through the movement of the servo unit th...
...Technical Information Injectors General Injectors have the task, during all driving conditions, to inject the correct amount of fuel calculated by the ECU. For good fuel atomisation and small condensation loss an engine specific distance to the inlet valve and injection angle a...
...Technical Information Inlet Air Temperature (IAT) Sensor General IAT sensors sense the air temperature on the inlet side of the engine. The voltage signal, produced by the sensor, is passed to the ECU. The ECU evaluates the signal and influences the fuel injection timing and ignition t...
...Technical Information Knock Sensor General You can find the knock sensor mounted on the side \ of the engine block. It recognises knock or pinging under all engine operating conditions to avoid lack of performance....
...Technical Information Level control switch for engine oil General Oil level control switches are fitted in the oil sump. They records the minimum oil level and send a signal to the ECU when there is an engine oil shortage. The ECU activate the warning system, a warning light or...
...Technical Information Level switch for windshield washer General The windshield washer switch records the low washer fluid level. They prevent a failure through water shortage. Function A magnet fitted in a float sinks when the washer fluid level is dropping and...
...Throttle Potentiometer General The throttle potentiometer senses the opening angle of the throttle valve. It send the information to the ECU to assist in calculating the correct fuel injection. The throttle potentiometer is fitted at the throttle valve axle. Function...
...Throttle Valve Switch General A throttle valve switch records the position of the throttle valve. It is fitted to the throttle valve spindle and send the information about the position to the ECU to assist in the calculating the fuel injection. Function Inside the...
