Hey guys I guess my oil pressure sensor went bad today. Throws the code p0523. I know I have oil and all that. Is it safe to drive around till I get the sensor changed? It’s really cold in my part of the country right now so I’m thinking if it’s safe to drive I’ll just do it in the spring. I have afm disabled with a Diablo sport tuner and it’s been off for most of the time I’ve owned the truck. It’s a 2008 5.3 with 155k miles.ol girl still runs strong. I just want to know if it’s ok to drive with the sensor bad. Thanks guys.

It sounds like you know what your talking about, so I'm not sure why you asked the question - but OK, here it goes:

 

As long as the sensor failure doesn't cause an automatic limp mode or other similar issue, then there is no drawback to driving with the oil pressure sensor disconnected.

 

However If you do develop an actual oil pressure issue without a functional sensor - then you will destroy the engine.

as long as you are sure its got op I agree with S pizza. I love the pix he comes up with. I didn't get a pic of it but I had a wrist pin go on 1 of my race cars. I knew the engine was junk so I started it to drive it onto the trailer the piston came out the side of the block and landed on the ground with the engine still running!

I am just curious why you cant change the oil pressure sensor and filter?  I get that its cold, but this is an easy job, and the part isnt that much money.  Hell even a off brand sensor is better then no sensor at all, especially if its cold.  Waiting till spring seems like a long time for this part.  Most cases when these sensors go bad they actually leak oil, so keep an eye on it

Pro-tip, run the engine for a little bit then crawl on top of it. You won't be that cold when the engine bay has some heat in it lol. Also park in the sun if doing it outside.

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!
