My check engine light is on and I am getting a code P0450 - evaporation control sensor switch. Can you tell me where this is located and how I can repair it?

Hello,

It's above the right rear axle remove the connector and check for corrosion clean with electrical contact cleaner if okay replace the sensor. I would also check the rubber lines because if one is split or rotten it will cause the code as well.

Here are diagrams that show the locations and hose routing of the EVAP system

Check out the diagrams (Below)

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
