All:

A couple weeks ago I had a code thrown that indicated an oil pressure sensor fault.  My mechanic in analyzing the code noticed that my oil was burnt and filthy having been changed only a few hundred kilometres previous.  He thought that maybe the oil change place put the wrong viscosity oil in and with the recent cold weather caused the fault and poor oil movement thus the burn and the sensor fault.  We reset the code, change the oil to Mobil 1 0W-20 and off I went.

Less than a week later and the check engine light is back on with I assume the same oil pressure sensor code attached to it.

Has anyone else seen anything like this?

Thanks in advance.

Your screen is most likely partially clogged.  I would change that out 1st.  If it looks very good change the sensor too!

It is making that whine.  Is there a definitive test for that pump failure?

I believe that is a fairly involved (expensive) repair.  It would be nice to be positive on that one.

Thanks for the good call.

Hi Silveradosid, 

I'm not aware of any specific test to confirm it without taking it apart and doing a visual inspection, but just others have said, if you hear a whine like a failing power steering pump it most likely is your engine oil pump and it is better to replace that sooner than later.

      Mediocre, how much did they lose on the poorly conceived EV strategy?   I wonder how much the stock price is being 'inflated' by all the buy-backs?   Cadillac literally looks like a brand without a rudder, no clear goals or product direction - performance or luxury? I guess performance because we can throw a small block in whatever we can and call it a day. Certainly not luxury when a Denali or High Country is reasonably cross shoppable. The Celestiq - no way - no vehicle can command quarter million prices when something wearing the same badge is on the buy here pay here lot across town.   Notice the 'base' Escalade doesn't even come with the 'leather-appointed' seating surfaces.   Hummer EV - fail Silverado EV - fail Sierra EV - fail Bolt/Volt EV (The most successful EV cancelled, restarted, cancelled, whatever its current status it)   Hybrids - none Sedans - none Medium duty - not anymore Minivan - none Coupe - none Convertible - none CUVs - 20+/-   6.2 Recall that landed squarely on the GMs highest seller - and specifically the fattest margin higher trims of the Yukon, Escalade, et. al. The most critical product line they fumbled big time. In the Escalade segment, are those buyers forgiving GM for a bad engine and patiently waiting for the fixes and dealing with the headaches? Nope, they dump them and go straight to the other premium brands.   In the ENTIRE GM portfolio how many aspirational vehicles are there? Corvette, Escalade (quickly being superseded by the obvious better value Denali)...   I posted somewhere else... what if Cadillac left the luxury game and became a performance brand similar to AMG or (gasp) Ferrari? Cut all the entry-level and base models from their line up and focus on the V-series or Blackwing or whatever they call it now. Of course, those would have the pre-requisite luxury and technology as standard equipment. This opens the floor for Buick to step in/up as the luxury brand (like they are in China), no 'performance pretenses' get rid of the 'entry-level' models with equally 'entry-level' power trains and become the Maybach to Cadillacs AMG. With those two brands effectively out of the way Chevrolet, the 'entry-level' brand has the floor to itself and GMC can take over as 'professional grade'.    Now each brand has a focus, no in-fighting, clear direction, and customer targets.   Just need to sneakily slide Corvette into the Cadillac brand and dump the vestigial script writing.

      I can't get enthusiastic about the 1.5T (or the 1.3 or the 1.2), I won't drive a CVT. But the stupid things sell in volume.

      There is a big difference in motorcycles and vehicles - nobody needs a motorcycle, they WANT one. That WANT is the most powerful force to drive price upwards.   I've hated every iteration of the Equinox, a prime example of GM laziness. It excelled at absolutely nothing, barely competitive by every metric. At least the latest generation looks decent.    I want to like the Buick Envista, but that pitiful engine plus FWD only is a BIG NO for me, I don't care how good it looks.

      auto mechanical driver's door unlock without pressing button? [2026 Silv. 1500 WT 4WD RC SB 2.7L]

      By bwiese · Posted

      Love my new 2026 truck - even as a basic WT it's comfy, rides nicely, etc.   Encouraged by the 100K powertrain warranty.   2nd GM I've ever owned (1st was a 2000SLE with Vortec V6 - loved that truck.) Small question - maybe I'm missing it in the manual? - but I seem to need to press the unlock button first, in order to open driver's door.  (Don't care as much about passenger door.) RKIs: is there any mod/setting change, etc such that when I merely pull the door handle it just unlocks + opens? I have minor concerns about ability to exit regardless of electrical performance. (I'm a bit limited agility w/osteoporosis from hyperparathyroidism - big guy, age 62, range of movement etc issues.) Thanks, Bill San Jose CA
