When a Crankshaft – Camshaft Position Sensor goes BAD, your vehicle will not start. Distributorless Ignition Systems (DIS) require a Crankshaft Position Sensor (CKP), and sometimes a Camshaft Position Sensor (CMP). So, the main difference […]
So, to determine the health of a head gasket, between two cylinders, try doing a bubble test. If you believe you have a leak, but just cannot find it, doing a bubble test may be […]
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, […]
The function of the automatic shutdown (ASD) relay, is to shut off power to major systems. When the key is turned off, as a safety feature. So, when the automatic shutdown (ASD) relay is on. […]
Crankshaft position sensors, produce a signal, that talks to the engine control module (ECM) / engine control unit (ECU). Consequently, providing the exact position of the crankshaft, as it rotates in the engine. So, now […]
Doing a cylinder leak down test, especially in conjunction with a compression test. Should allow you to quickly determine, the basic condition of any engine. So, a compression test is a “dynamic test” (engine moving). […]
A Vacuum leak can trick you, and your car computer into believing a particular sensor, or system needs fixing. Then, you start replacing components, hoping you’ll fix the problem, unsuccessfully. Often, a vacuum leak makes […]
So, have you ever thought about using a vacuum gauge, to check the condition of your engine. Consequently, this is similar to doing a cylinder leak down test, but in a much easier way. Vacuum […]
The job of engine coolant antifreeze, is to protect the engine, from severe temperature and corrosion. Always flush and replace your engine coolant antifreeze, at recommended intervals. Otherwise, it will break down and not perform […]
So, Engine Compression is the pressure created, inside each of the engine’s cylinders. And, low or no compression leads to, incomplete combustion and misfires. Symptoms of low engine compression can be, an illuminated (CEL), and […]
Doing a cylinder leak down test, can tell you more about your engine than you think. Also, a cylinder leak down test, can pin point issues in specific areas, that other tests can not. So, […]
Vacuum leaks in today’s computer controlled engines, can cause very serious engine damage. When an engine that has computer controlled spark and fuel systems, have vacuum leaks, the following events occur. Because, these leaks pull […]
So, performing a cylinder power balance test can help uncover, hidden engine issues, commonly missed with other tests. Cylinder power balance testing, can find issues related to, engine misfires, lack of power, or just a […]
So, a catalytic converter, is a device used to reduce the emissions, from an internal combustion engine. Consequently, the catalytic converter works, by breaking down unburned gases, left over by the combustion process. But, requires […]
First, doing a vacuum test, can tell you more about your engine, than you think. Because, it is one of the easiest and least expensive ways, to check an engine for serious issues. So, engine […]
