2 New Oil Pressure Sensors Blown in 2 weeks--ya think it's me?

It's the easiest job in a jeep--I know I did it right.

All I can say is one lasted 3 hours and the other lasted a week.

The only thing both failures had in common is they both failed on the interstate doing 65 mph.

That tells me the pump was under load, but I don't know why the part malfunctioned twice.

My engine bay harness appears fine, fuses fine.

It has a warranty I can get a new part. But in y'alls humble opinion is 2 failures a coincidence (crappy sensors) or is the problem with my rig?

Thanks, Brent

You can test with a Engine oil pressure tester with gauges to see actually reading. A friend of mine is a mechanic and tested mine because I had a sending unit fail a couple weeks after I installed it. My gauge was also peaked so I wanted to be sure. I either have a bad gauge or wire from gauge to sending unit. Not sure if local auto parts store have loaners but try there first.

That's a start--thanks.

By blown I take it to mean they started to puke oil? Like Rnvan says, at this point I would check the oil pressure mechanically to determine if its the sensors or a problem in the oiling system..

Gary, sorry I wasn't clear--I meant both new parts worked for a while then just pegged out at 80 p.s.i. and never came back.

could be

It could be a bad sensor. It also could be that the relief valve in the oil pump is sticking and the pressure is spiking. Extremely high oil pressure would likely happen at higher rpm. Could be a bear to isolate and trouble shoot. If it is, the relief would likely stay locked until the pressure is relieved enough to let it release.

You could get a mechanical gauge that has the actual oil flow to it as a temporary check. Run it in parallel.

I would try another sensor as that is still the most likely.
