What is an EGR Tube and what does it do?
The EGR (Exhaust Gas Recirculation) valve takes a small amount of exhaust gas from the exhaust manifold and pushes it into the intake manifold to help with emissions. Depending on placement in the engine bay, the EGR may use an tube to properly reach between the intake and exaust manifolds.
What causes an EGR Tube to go bad?
There are a few different reasons to replace the EGR tube:
EGR Valve - This part is usually the first part checked when there's an SES light regarding the EGR system. Since it moves exhaust gases, it can build up with carbon and fail to open and close properly.
EGR Valve Temperature Sensor - The EGR Temp Sensor is one way a vehicle's PCM monitors the EGR system's operations. A bad sensor reading can cause the engine computer to incorrectly calculate spark and fuel.
Intake Manifold - Some of the newer plastic intake manifolds have experienced failure due to the heat of entering exhaust gases.
Exhaust Manifold - a crack or stripped threads at the EGR port of the exhaust manifold can result in a exhaust leak, "check engine" error codes, and failed emissions inspection.
