I keep getting the C0035 code. Is there a way to fix the speed sensor without replacing the whole hub assembly?

The code is for a left side, front speed sensor fault. That is per the code explanation list on this site and others.

Oh oh me me! I want to tell him!

 

"Don't throw parts at it. Go get it properly diagnosed"

 

Now that that is out of they way, my personal feeling is, if you have to take it apart to change the sensor, change the whole hub. That way there's new bearings and all.

Im trying to avoid throwing parts at it. I was wondering if there was any other fixes beside replacing parts. Maybe I should have reworded my question.

 

What are some common issues that will throw a code like this, and are there any easy fixes? Ive never worked with a speed sensor so Im not sure if it is servicable, or if its something you cant get to because its inside the hub assembly. im kinda hoping that someone on here has had this code before, and I would like to hear how they fixed it.

 

On a related note, what does this sensor actually control, and is it safe to drive on with a faulty sensor?

First. Have you checked the hub making sure it's good? Next, you can remove the sensor and try cleaning the mounting surfaces. Good chance your bearing is going

 

safe to drive? As long as it's just a faulty sensor, not a wheel bearing, you can drive all you want. I think your ABS will not operate

Didnt realize the bearing itself would cause this code. I figured it would be going sometime soon though. Had the right side replaced at 90K, and figured I wouldnt get too much firther on the other one. Got 20K out of it though.

 

Ill check the contact surface and stuff first though.

Swung by the mechanics shop this afternoon, just to have him check my hubs for slack. i would have done it myself, but I was in a hurry and didnt want to get dirty. He checked the hubs for slack, and said they feel tight. He said he has had to replace both sides of his truck 3 times (2007 2500 Duramax w/ 90K) I hope I have better luck than he does.

 

So, Im gonna run back up to the shop tomorrow and see if I can clean the sensor any. I did get the truck burried up in some sticky mud a few weeks ago. Could that be the problem. Im not getting any slack or any noise from the hub bearings. Does that mean its OK or could it be jhust startingto go bad? I only ask becaus Ive never replaced one before, but after paying $700 to have the other replaced, Im gonna try to get it replaced if I can do it in my driveway with a socket set.

Wow, for $700 I think I would go buy all the tools I needed to fix it, and find out how to do it myself. The prices that some of these garages charge are highway robbery. Then they wonder why people try to fix it themselves instead let alone go to the shop or especially the stealership.

OK, got the sensor out and noticed some rust on the contact. Cleaned it off and after reinstalling, I noticed a tick when i rotated the hub coming from the hub/knuckle assembly. Tried getting the hub off to isolate it and see if that was the noise, but I dont have a socket big enough for that nut on the axel.

 

What size is that btw?

OK, now a bearing question. I was looking on Rock Auto and there are a huge list of hubs to choose from. Were the factory hubs AC Delco, or made by someone else? Ive seen several times where another company makes the part and its just rebadged as AC Delco and marked up, when the exact same part is labeled by the manufacturer for half price or less.

 

 

Out of Timken, Moog, Raysbestos, or SKF, which brand would you choose. They also list AC Delco, but they are almost double. Is it worth it, or just a factory part markup.

 

 

Just to be clear, Im not throwing parts at it. I was just looking at part prices in case the ticking was the hub.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔
