Talking Oil Pressure Sending Unit

Hi all savvy PT'erz!

I had to replace our Oil pressure sending unit/switch this weekend because it was causing an oil leak. I just wanted to give everyone some tips.... It is very hard to try to reach the sensor from under the car. What we did was we removed the battery, air box, we also moved the fuse box aside just a bit to get more room to work (not necessary though). After removing/moving those parts we had plenty of room to work with. Simply disconnect the electric connection and remove the sensor with a socket. The part was $11.99 at Kragen with a lifetime warranty! (not just a dealer only item :]) The socket isnt a special socket its just a 27mm ($9.99) deepwell. I hope this helps someone, overall the job wasnt hard so no need to pay anyone to do it for you! :]

Is there a difference if it is a turbo?

Just did mine last week on my base PT. If your arms are long enough, you can access it top passenger side and reach wayyyy down and you won't have to remove anything! Its good to put her up on ramps to get and idea where it is, then take her off and do the repair. You forgot to mention unlocking the electrical connection by pushing the slide lock to the side. Just curious, what year and mileage on your PT?

Does anyone have a picture of what this is supposed to look like, i've had a problem with this damn leak for a while now. first they thought it was the corner of the pan, then they said it was a pinched seal on the oil filter, now they are at the point where they believe it is higher up, some type of oil pressure switch. I'm assuming that this is what is being discussed on this forum. just want to make sure before i start taking things apart.

Thanks,

Anthony

Take note that it Should take a 27mm socket to get it off but mine ('03 GT) took a 26mm, and a 27mm for the replacement.

It should take you no more than about 5 minutes to replace it... and the part is less than about $15

Update: The 27mm was too big, 26mm too small, 1 1/16th inch perfect fit!

Turns out the real problem is the Cam Seals have gone bad, i can see oil on the teeth of the timing belt when i look through the cover. Can Anyone tell me the difficulty level on replacing these seals?

not sure, but when i took mine in for the timing belt, water pump, etc they called and asked if i wanted the cam seals replaced as well for an additional $14.

hopefully you won't have to go with the whole tb procedure just for that.
