Can a knock sensor cause your engine to knock?
3. Detonation Knock: Bad Knock Sensor. Luckily, engine knock isn’t a frequent problem with modern cars, because the air/fuel ratio, fuel injectors and timing are all computer controlled. This naturally means that a bad knock sensor can allow the engine to knock.
What will happen if I remove my EGR valve?
If the EGR valve is clogged or completely blocked off it can longer re-burn harmful emissions in the combustion chamber. The NOx emissions will flow unregulated through the combustion chamber and out of the exhaust pipe.
What are the signs of a bad EGR sensor?
Common signs include engine ping or knock, the Check Engine Light coming on, and failing an emissions test. 1. Engine ping or knock 2. Check Engine Light comes on 3. Failed emissions test Average rating from 129,472 customers who received a Exhaust and Emission System Inspection.
What should I do if my EGR valve is not working?
Remove the EGR valve and check if it’s opening when you are using the vacuum pump. If the EGR valve is working properly, check the solenoid that is controlling the EGR valve, and check if you have power and ground to it.
What are the symptoms of a bad knock sensor?
The Top Signs of a Bad Knock Sensor. When the knock sensor fails, it will usually cause one or more noticeable symptoms. The most common knock sensor problems include: Illuminated Check Engine Light. The most common sign of a bad knock sensor is an illuminated check engine light.
Is the EGR temperature sensor part of the solenoid?
The EGR temperature sensor is an engine management sensor that is part of the EGR system. It works together with the EGR solenoid to control the flow of the EGR system.

What causes black smoke from the EGR valve?
2. Black Smoke from Exhaust. If the EGR valve stays open at all times and the exhaust fumes are being fed to the engine constantly, the engine gets deprived of oxygen. With too much fuel burning and less oxygen, a black smoke gets produced and escapes from the exhaust pipe especially when the car is idle.
