The plunger did not move I did clean it same issue. What is the voltgage level that I should see?

 

there is no true range given...its just discribed as 'battery voltage' basicly if there is no reading of voltage you have a break in the line...a bad sensor..or a faulty PCM.....what will happen if you take it in some where they will have a scan tool that they can plug into the sensor its self to tell them if there is a problem there....these tests are just simple (and probably in acurrate) things to do to try and see a problem. Do you have an auto zone near you?? If so take a quick ride up there and have them figure out what code you are throwing...
