As the crankshaft rotates, the sensor produces a pulsed voltage signal, where each pulse corresponds to the tooth on the reluctor ring. The photo below shows the actual signal from the crankshaft position sensor with the engine idling. In this vehicle, the reluctor ring is made with two miss...
Before a vehicle can drive, the engine draws a mixture of fuel and air into the combustion chamber, which burns to turn the crankshaft and other engine components so the vehicle can move. The spark plugs ignite the fuel/air mixture by creating a spark that causes the mixture to explode, ...
Some drivers want as much information as possible about their driving and their car; people with displays that show real-time fuel economy information might make a game out of trying to improve their driving with each mile. The need to control additional technology, from power mirrors to a...
In essence, it takes the electrical voltage from the battery, converts it to a much higher voltage, then transfers this electric current to the engine’s combustion chamber and ignites the compressed mixture of fuel and air to create combustion. This combustion generates the energy needed to run...
The ECM is tasked with providing fuel and regulating emissions, but there's a lot that needs to happen for that to work. We already talked about the ECM's specific tasks, but that simplifies the process a bit too much. The ECM usually monitors and regulates the throttle position sensor, ...
The amount of air being drawn into the engine is a good indication of how much power it is producing; and the more air that goes into the engine, the lower the manifold pressure, so this reading is used to gauge how much power is being produced. Engine speed sensor - Monitors engine ...
ADS relay has a purpose always. It will not provide power directly to the fuel pump. It will providepower to fuel pumpif there is a cam or crankshaft portion sensor that detects at the ECU or PCM; in a single line, it’s unnecessary. ...
the O2 sensor will fail. This might happen at 100,000 miles, or sooner. When it does happen, you will notice a dramatic decrease in performance. You may not be able to start your Accord, or your Accord's idle may be really rough. At this point, you need to replace the O2 sensor....
Replacing the timing belt is a necessary evil. It's not an easy job, but not the hardest you could do either. Having a shop replace the t...
Start the engine and let it idle for three minutes to bring it up to operating temperature. then turn off the engine. You can remove the oxygen sensor much easier with the exhaust system above 120 F (48 C). Step 2 Lift the front of your Chevy Venture using a floor jack and support ...
