    New Car EGR Vacuum Modulator Hamilton

    What is the EGR vacuum modulator?

    The EGR vacuum modulator is an important part of your car’s EGR system. The exhaust gas recirculation (EGR) system causes exhaust gases to be sent back into your engine via the intake manifold. The gases are then re-burnt, allowing for a decrease in harmful emissions from your car’s exhaust.

    The EGR vacuum modulator is a component found in many EGR systems. It modulates intake manifold vacuum which controls the flow of exhaust gases through your EGR system. The vacuum modulator will turn the vacuum on and off to regulate EGR flow in accordance with combustion temperatures in the engine.

    If the EGR vacuum modulator encounters problems, your EGR system will not be able to function properly. This can affect your engine’s performance, fuel economy and increase emissions or cause serious engine damage over time (due to overheating).


    Symptoms of a faulty EGR vacuum modulator:

    Reduced engine performance – If the EGR vacuum modulator diaphragm becomes damaged, it can create a vacuum leak which will affect the performance of your engine. This often translates to reduced engine power, high idle rpm, increased stalling and higher fuel consumption.

    Increased emissions – A faulty vacuum modulator can cause your car’s exhaust to produce more green house gas emissions. As well as being bad for the environment, excess emissions can also lead to your car failing its Warrant of Fitness.

    Overheating – A faulty Exhaust Gas Recirculation (EGR) vacuum modulator can lead to higher engine temperatures. This happens due to the modulator not enabling the vacuum when necessary. If you suspect your car’s engine temperature is rising, keep an eye on the temperature gauge and pull over if the level continues to increase. Driving with an overheating engine can cause serious damage to your engine’s cylinders and should be avoided.
