My 2010 Traverse had a low oil pressure alarm that would ring out loud non-stop while driving.
I bought this AC Delco Oil Pressure Sensor (GM# D1843A) but couldn't get the old one out.
I had my mechanic put one in and that fixed the constant ringing alarm.
Now my 2010 Traverse LTZ doesn't need this brand new one.

I was about to take the sensor to Goodwill but I'd rather get it to somebody who could use it.
I estimated the price at $15 because I'm not trying to make any money on the sensor. I'm just trying to have the shipping paid.
If you have a better shipping rate you could send me a shipping label and I'll send you the sensor & socket at no additional charge.

PS: I'll include the special socket that's made to fit the sensor. (Lisle 13250 Oil Pressure Switch Socket)

Everything new was about $36
