EGR valve stuck open The Exhaust Gas Recirculation (EGR) valve is an important part of your car’s emissions system.It recirculates exhaust from the engine’s combustion chamber to burn again rather than sending it to the emission system, thereby reducing emissions. The EGR valve opens and clo...
After months of service, the Exhaust Gas Recirculation (EGR) valve in your Ford Taurus becomes dirty with carbon deposits and road debris that from time to time may become lodged between the diaphragm and its mounting base. Cleaning the valve is a simple process if done carefully. The guide ...
Engine speed sensor - Monitors engine speed, which is one of the factors used to calculate the pulse width. There are two main types of control for multi-port systems: The fuel injectors can all open at the same time, or each one can open just before the intake valve for its cylinder ...
The first step is to open the hood. However, don’t forget that the engine should be sufficiently cool before you remove the radiator cap or reservoir cap. If theengine is hot, give it at least an hour or longer to cool down before you attempt to check the coolant. If the engine is...
A heat-resistant ball valve and insulated Y-connector were used to switch between up- and downstream. The temperature of the transfer lines and the valve was always set at 200 °C. In the case of MC1 (fuel comparison, no scrubber), only one sampling point was used (Au) with the same...
low fuel pressure or an EGR valve that is stuck open and leaking exhaust into the intake manifold. If a random misfire code is also accompanied by a P0171 code (cylinder bank 1) or P0174 (cylinder bank 2), it will help isolate the lean fuel condition to one side of the engine or ...
Park your car on a level surface. Turn off the engine. Open the hood and let the engine cool down. You want the engine cool to the touch before you begin to disconnectthe mass air flow sensor. Step 2 Trace the plastic air flow tube back from the air filter housing until you locate ...
Failed Emission Tests: If your vehicle fails an emission test, it means that it is not meeting the required emission standards. This can be due to various factors, such as a malfunctioning catalytic converter, oxygen sensor, or exhaust gas recirculation (EGR) valve. Proper diagnosis and repair...
the mass airflow sensor and MAP (manifold absolute pressure) sensor, which monitor different ways air affects the engine; the oxygen sensor, which measures exhaust quality; idle control; the EGR valve sensor, which also helps with emissions and the ignition control, which regulates the spark plug...
EGR Valve The Exhaust gas recirculation (EGR) system redirects a small amount of exhaust gases back into the engine intake to reduce the combustion temperature. The EGR valve is the main component of this system. By opening and closing It controls the flow of exhaust gases within the EGR syst...
