The, (O2) Oxygen Sensor, measures the difference, between the amount of oxygen in the exhaust gas. And, the amount of oxygen in air. So, with that information and other sources, the (ECU) can decide, whether […]
The engine coolant temperature (ECT) sensors function, is to monitor the temperature, of the engine’s coolant. So, most engine coolant temperature (ECT) sensors operate, using electrical resistance to measure, the temperature of the coolant. The […]
So, almost all newer vehicles on the road today, use a mass air flow sensor. The mass air flow sensor, measures the volume and density, of the air entering the engine. In addition, it also […]
The engine coolant temperature sensor, is one of the most important, engine management sensors in your vehicle. So, a sensor that is shorted or reading out of range, can’t provide a reliable signal. Consequently, engine […]
The most important sensors, in any engine, are the crankshaft and camshaft position sensors. Modern computer controlled vehicles, must have the air and fuel ignited, at the proper time, in order to operate efficiently. Both, […]
So, the throttle position sensors function (TPS), is to supply vital information to the vehicles, engine control unit (ECU). Most importantly, this information is based on, the actual position of the engines throttle valve. So, […]
Before the use of computerized automotive sensors, fixing a car was way easier. In the old days, it was a lot different. For instance, either moving a distributor, or adjusting a screw on a carburetor, […]
Crankshaft position sensors (CKP) read ignition timing, the (RPM) signal, and determine engine speed. But, when the crankshaft position sensor (CKP) fails, it stops transmitting the readings. Consequently, the crankshaft position sensors (CKP) readings, contain […]
Replacement of a good Oxygen Sensor (O2), is a common mistake made by (DIY) mechanics all the time. Therefore, before replacing any of these oxygen sensors, you must find the real problem first. So, the […]
There are a number of symptoms, that can point to your Crankshaft Position Sensor (CKP) failing. But, can also be confused with the same symptoms, caused by issues with, your ignition or fuel injection system. […]
So, the idle air control valve (IAC), is responsible for managing the engine’s idle speed. Most importantly, the idle air control valve (IAC), is a major management component of the engine. Therefore, decreasing or increasing […]
Every vehicle built since the early 1980’s, has one or more (O2) oxygen sensors, integrated into the exhaust system. So, (O2) oxygen sensors, are used to confirm, that the proper air fuel ratio, is actually […]
