This past couple of weeks I noticed my temperature gauge wasn't working well - it sometimes worked, sometimes not - or that the engine was running very cold (doubtful).

 

Today, my 2006 GMC Sierra 1500 SLE2 5.3L threw a P0116 code. Any relation or is this something else?

 

I have modified my engine block plug and replaced the end with a generic one to remove the temperature sensor. This cause that?

You're talking about the block heater right? That you removed the temp sensor on the plug for it. Yes you can get a code set. Don't know if it's that specific one, but I do know there is a problem. Thta't one reason why the stock units don't come on until is pretty damn cold.

Yeah, I cut the block plug heater off at the end (where the temp sensor is) and presto - block heater comes on when I say. :lol:

 

So, that code is for the block heater plug end then? (phew!)

I have two pickups (2012 and 2000) both with 5.3L engines and an 2006 Impala SS w/5.3L. the last couple of days the Impala has shown the temp code P0116 and we had the block heater plugged in because it has been -25c to -30c but was only -15c the last couple of nights. It has a factory block heater but it doesn't have a temp sensor on the plug (it's original and I'm the original owner and haven't changed it) How can I reset the code? I will remember not to plug it in when the temp is above -18c.

Disconnect the battery for a bit

Get a handheld scanner that has the capability of clearing codes

Find an auto parts store that will do it for you

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?

      Tire psi

      By jgaudet99 · Posted

      That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?

      Would this CV Shaft be bad?

      By newdude · Posted

      That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?

      Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
