Subsequently, one may also ask, what problems does a bad EGR valve cause?
A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.
Additionally, how can you tell if the EGR valve is bad? Symptoms of a bad EGR valve include:
- rough idling or stalling.
- a smell of fuel.
- increased fuel consumption.
- pinging, tapping, or knocking sounds.
- failed smog test.
- Check Engine Light on.
Similarly, can a bad EGR valve cause coolant loss?
Loss of Coolant - all that coolant evaporating inside the cooler and then blown out through the exhaust will ultimately cause your coolant levels to drop. Now, a loss of coolant isn't always indicative of EGR Cooler failure, but when accompanied by white smoke, it's a pretty safe bet.
Can EGR cause rich condition?
It can also burn holes in exhaust system components and destroy your vehicle's catalytic converter. EGR Valves allow burnt exhaust gases to reenter the intake manifold, causing a rich fuel condition by reducing the amount of oxygen.
