My truck doesn't have that feature. Hope the wife doesn't read this. [emoji23]

This is interesting. I had an old 1999 K1500  with this exact same steering position sensor. Basically, the ECU used the sensor, and RPM value to vary your power steering pressure and make turning easier, mainly in low speed applications. At one point, my sensor failed and starting producing erratic signals, and it caused my truck steering to intermittently get super light. In turns it would cause you to "over turn". It really freaked me out the first time it happened.  Some people would completely disconnect this sensor when it failed. However this would cause harder steering in low speed turning applications, because obviously, the power steering pump never knew if you where turning, therefore it would never increase pressure at low RPM, making it harder to turn. Most folks said it didnt make much of a difference.

 

Anyway, Id assume this sensor is used to lighten up your steering when turning at low speeds. Disconnecting it will disable this feature. Thankfully though, you will not get odd functionality like I did when my sensor was going out. 

I tried pulling my fuse many months ago to disable Stabilitrak and ABS, but my steering was negatively affected. Your description is exactly what I experienced. The messages I got were "Service Stabilitrak" and "Steering Assist is Reduced Drive with Care." Even after replacing the fuse, I still had messed up steering. It was fixed after I cleared all of the codes (and there were lots of them).

 

I'm wondering if removing the steering position sensor messes up the steering like pulling the fuse did.

And what happens when you plug it back in? Does everything go back to normal? Are there codes to clear? Are the reverse lines in your back-up camera misaligned now?

I can't say I noticed any difference with the steering from unplugging the sensor but I have only done it when there is snow on the ground so maybe the extra assistance at slow speed is less noticeable.

I had the same errors come up but they went away after plugging back in & starting the truck.

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
