If your Dodge or Chrysler product is having EGR valve or backpressure sensor issues, it's easy to replace the assembly and clean the system around it.

First, you'll need to remove the assembly. Let's go:

  1. Inspect the vacuum line that is connected to the backpressure sensor (or transducer) to see if it is dry, cracked, split or has any holes in it. Remove the hose and if it looks questionable in any way, toss it and replace. New vacuum hose costs nothing at the parts store.
  2. Remove the bolts attaching the EGR valve to the engine and remove the valve. Be careful not to damage any of the electrical wiring coming from it.
  3. Disconnect any of the electrical plugs going from the EGR valve to the actuator solenoid. (see pic)
  4. Remove the backpressure transducer (it should be held in place with clips)
  5. Clean the area around the removed parts with EGR cleaner. Be sure to scrape away all of the old gasket on both surfaces. You'll be installing a new gasket.
  6. Now install your new EGR valve onto the engine with the new gasket.
  7. Install and reconnect the backpressure transducer, the reattach all your electrical plugs removed previously.
  8. Install the vacuum line. You're done!
