Customer Question
2004 cadillac escalade with...

2004 cadillac escalade with 208k "low oil pressure" warning chiming on display. Recently changed the oil pressure sensor. Prior to; no issues. No smoke, no rough idle, no oil burn, no knocking or pinging. Someone told me the engine is shot. I beg to differ

Mechanic's Assistant: Is the rough idle intermittent or consistent?

No rough idle runs like a kitten

Mechanic's Assistant: Are you fixing your Escalade yourself? What have you tried so far?

Shop stated they put heavier oil, my oil pressure warning has stopped. however he told me dont drive far and look into replacement. I dont think so, no power loss or anything. Didnt get the warning until he replaced the oil pressure sensor

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Should I look into replacement?

was not working
Cadillac Mechanic: Dan, Technician replied 11 months ago

How wasn't it working? If it wasn't working I'd assume you were getting the low oil pressure warning before having it replaced too?

no warning, the guage read 0 (zero) drove like that for months without a problem, then decided to get it fixed.
Cadillac Mechanic: Dan, Technician replied 11 months ago

That is strange it wasn't giving you a warning before, it should have. Any idea if shop did a oil pressure test? This would be a for sure way to know if engine is problem or not.

not sure, he just told me he added heavier oil, and it would be fine to drive just dont go far.
Cadillac Mechanic: Dan, Technician replied 11 months ago

Well at this point I'd recommend a oil pressure test, if oil pressure is low then you know engine is not producing enough pressure. If that is the case it is likely been going on the last few months so you will probably be good for awhile yet, I'd just keep the heavy oil in it. If oil pressure is good then next step would be to verify wiring going to sensor is good, and if so replace with a OEM sensor. Oil pressure should be at lest 6 psi at 1000 rpm, 18 psi at 2000, and 24 psi at 4000 rpm. Let me know if you have more questions, thanks.
