    Does all the sensor switches run together ??????
    , I have an oil leak to where you just changed out. My tire pressure senor switch is out too. It needs replaced too. At the chevy garage they wanted 400.00 to switches out all 4 sensor switches. They said they changed out the oil sensor switch. It kept leaking. They said in so many words that I needed all 4 done. Is this true. I do want the changed out But it's the 400.00 that's making me unhappy. If I can watch videos of how to change them out, I'll do it my self…
    They already charged me $134.56 to change out the one oil switch, that didn't fix the oil leak.. Ty

    Good video. Put some gloves on dude. Those chemicals including oil get absorbed through your skin.

  4. Avataaar/Circle Created with python_avatars Soup Sandwich says:

    Those switches are about useless. I had one go on an 01 Impala with no indication the oil was low. 🤦‍♂️

  5. Avataaar/Circle Created with python_avatars Calmness & Chaos says:

    i changed my oil pressure switch, its still leaking and I have not idea where to start.

  6. Avataaar/Circle Created with python_avatars Kayla Davis says:

    Where else could it leak that badly from?? Mine is as bad if not worse. And i can hear it leaking with the hood down now that the oil is gone (dont plan on starting it again till it has at least a qt lol)

    Well as old as this video is, this was the oil leak problem on my 07 Chevy Impala. I could not find the oil leak, had the car on the jack to replace the outer tie rod, saw the oil leak coming from the oil filter. Thought the filter was loose, sine we just had the oil done. Nope.. Took the oil pressure sensor off had oil in the connector , replaced sensor. Thanks Eric O

    Great vid. I've got an 06 impala with the 3.5 and sometimes I'll get a low engine oil message and recently it's been marking its spot in the parking spot. Hopefully that's it's only issue and it can keep on running

  9. Avataaar/Circle Created with python_avatars Gregory Kusiak says:

    I developed a leak on my 3.5 somewhere above my starter…now I know where to look. Switch gets changed out with the oil tomorrow. This is a better problem to have than a seal/gasket. Thank you.

    Ive never seen a sensor leak like that something new?

  11. Avataaar/Circle Created with python_avatars Michael Andrews says:

    Good video I know how to change mine now. So I'll now if that's where my small leak coming from.

  12. Avataaar/Circle Created with python_avatars Hola! Bill Malec says:

    Oil pressure switch leaks. Hey, my oil pressure is low. What is it? The switch that tells you the oil pressure is low. Great idea to have one 🤷🤦
    I think I'd rather just plug that hole.

    98 chevy venture 166xxx3.4 fuel pressure regulator squealing changed 2 still the same?

  24. Avataaar/Circle Created with python_avatars Hector Torres says:

    I just want to know where can I get it done and how much it will cost me

  25. Avataaar/Circle Created with python_avatars Hector Torres says:

    you took a lot of parts just to get to that and to know exactly where everything belongs you had to have real passion for that I'm afraid to have a mechanic dude that what you just did he might not put back the bolts back where they belong or even Twerk it the way you did

  26. Avataaar/Circle Created with python_avatars Hector Torres says:

    too bad you don't live in Reading Pennsylvania I would like you to do mines how much would you charge

  27. Avataaar/Circle Created with python_avatars Hector Torres says:

    how much does it cost for a mechanic to fix that I have a similar problem like that I just want to know how much it would cost me

  28. Avataaar/Circle Created with python_avatars Anita CRADDOCK says:

    Thanks so much. Just had that happen on a trip in my Pontiac aztek. That could be an engine killer. Your video gave me an answer and a fix instantly. All thumbs up. Thanks again…

  29. Avataaar/Circle Created with python_avatars Kenny205 says:

    This was EXACTLY MY PROBLEM!!! THANKS ALOT!!!!

  30. Avataaar/Circle Created with python_avatars Ben Johnson says:

    Glad I watch this video. Just replaced tranny pressure transducer switch on my 2001 Jeep Grand Cherokee 4.7 L V8 with transmission 45 RF. was wondering how to clean up the electrical connector. Thanks for showing the detail with the brake cleaner and air nozzle. The transmission fluid had been leaking through the pressure switch for some time before I found one single YouTube video about it. Says it is a common sensor failure, could result in a short circuit but did not show how to clean up the electrical connector. Well I broke the Locking tab trying to get it apart wonder how long it will hang on there? What's the best remedy? any suggestions? Pretty limited access

  32. Avataaar/Circle Created with python_avatars larsnars says:

    Is the 2001 Chevy 3.4L the same to fix ?

  33. Avataaar/Circle Created with python_avatars Azael Estefania says:

    Thanks good luck Erick

    Nice!

  35. Avataaar/Circle Created with python_avatars Jim Haldeman says:

    All car engines leak. Just check the parking spots in any shopping center parking lot. Your car did not make them all. Oh yes drive slower and less too. Ask yourself if this trip is truly necessary.
