  1. Replacing a broken vacuum line to the EGR valve or control solenoid. Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it if it does not register enough of a temperature change.

How can you tell if the EGR valve is bad?

What are the signs and symptoms of a malfunctioning EGR valve?

  1. Your engine has a rough idle.
  2. Your car has poor performance.
  3. You have increased fuel consumption.
  4. Your car frequently stalls when idling.

What is the exhaust gas recirculation control circuit?

The exhaust gas recirculation (EGR) system helps to reduce nitrogen oxide gases in your vehicle’s exhaust by detecting an open circuit condition of an EGR motor control circuit for more than 3 seconds with the ECM/PCM.

Where is the EGR solenoid located?

The EGR solenoid is normally attached to the engine block with a nut and is located close to the EGR valve. It can be found by following the rubber vacuum hose from the EGR valve on the back of the engine block to the solenoid. Replacing the EGR solenoid takes only a few minutes and you can save time by doing it yourself.

  2. Replacing a broken vacuum line to the EGR valve.
  3. Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it.

Can EGR cause rich condition?

EGR Valves allow burned exhaust gases to reenter the intake manifold, reducing the amount of oxygen available and causing a rich fuel condition.
