This part is no longer available from Dorman (part #590-206). BUT it appears that some of the Advance Auto Parts - Carquest family of stores still have this part on the shelves as old stock. I noticed that you can use their 20-25% coupon codes to make an online order and then pick one up at a nearby store (seems like only Carquest stores have this part) or just do a ship-to-home order for about $140. I actually spoke with Dorman tech support. This part was sourced by the OEM in Singapore and they stopped making the part for Dorman so its 100% over with. Once they're gone, they're gone. I'm not sure where WVE is getting the part from nor where ACDelco is getting them (new part #85598007 $215). I opted to go to my local U-Pull U-Pay lot and started to grab these off of trucks. Bring a multimeter to test them to make sure you're not grabbing junk. You should get some sort of ohm reading/continuity. If its open (no continuity) then the sensor is garbage. If the sensor has a bulge behind the stick or a crack, it is from corrosion and the sensor is destroyed. Another piece of free advice: the 15297468 sensor is ONLY compatible with 2007-2008 GMC Sierra and Chevrolet Silverado 1500's. Not 2500HD or 3500HD nor the SUV's. That specific part number (15297468 or 85598007) will only work with the 07-08 half ton pickups only. This is part of the system design and that is for a reason. I wouldn't screw around with Supplemental Restraint System (SRS) parts; just do it right.

Yes that will be fine. Just don't overtorque that one either!

I live in the Rust Belt but I work in Colorado. They definitely get snow out here but they don't salt the crap out of the highways like in the Midwest. I recently picked up an '08 Sierra ext-cab 4x4 that was owned since new by the State of Colorado. This truck is 16-years old and has been through at least 15 winters. Frame and undercarriage are extremely clean. This was not a garage queen either. Cars can rust out here but I think that most people wash their cars frequently and the cities don't dump a million pounds of salt on the roads contributes to the lack of destroyed undercarriages. My word of advice after living in the Midwest: if you're buying a used truck, buy it from the Southwest. Make a mini-vacation out of your trip to drive it Northeast. Then hammer that undercarriage with aggressive countermeasures such as Mud Guards (to prevent the sandblasting of your rockers and body panels) and Woolwax or Fluid Film. Make sure whoever does it that will coat the inside of the cab corners and fenders. Its amazing how Canadians in Northern Ontarior seem to not have issues with rust as many do exactly what I just discussed. They spend the $120-150 or so every year to have the undercarriages, frame rails, and body panel insides coated. That technique unequivocally works.

Is it possible to use a steering wheel from a Buick Lucerne or Cadillac DTS as they look the same? Or are there differences in the steering shaft and wiring? Should I stick to the trucks instead (Denali, Chev LTZ, Esky, etc) when searching for a wheel?

Did you update the software? Either find someone with a Tech2 and laptop (or just an MDI and a laptop) or take it to the dealer.

Have you actually done this for these HD trucks? I’m not sure if I need to spend the $15 in new bushings or $300 for two new entire LCA assemblies.

Well if the TPS is bad, rapidly moving the butterfly could easily cause a fault as the electric stepper motor position is not in alignment with what the TPS is reading thus causing a fault - reduced engine power for safety. Basically to prevent an MCAS issue lol Sent from my iPhone using Tapatalk

Wow I didn’t think that GM used the electronic TB in MY2002. Funny as my Tech 2 asks me if it has the electric throttle for my 2002 6.0 2500HD. Your part numbers from RockAuto are: 17113659 for the entire assembly $250ish (with RPO NW7) 17123852 for the sensor without RPO NW7 $32 (TH149 at big box stores) 17114566 for the sensor with NW7 $53 (TH298 at the big box stores) That has got to be a first generation LS electronic throttle as it looks huge. I’d started with the sensors. Maybe even from your local big box store so you can return it easy if it doesn’t fix the problem. If you do order from Rock don’t forget to use a 5% off coupon code.

I’m referring to the actual sensor on the throttle body. What year is your truck? GM has had a lot of issues that go back from 2003 to 2012. Some people spend the $110-170 for a new entire throttle body assembly. The sensor kit is about $28. Takes about 15 min to replace. Sent from my iPhone using Tapatalk

This part is in stock at your local big box auto parts store and also your local dealer. What year is the OP’s truck? It may be covered under recall; my ‘09 Tahoe was covered under GM recall last January. I ended up doing it all by myself as my dealer had a two week backlog and Amazon delivered the part in 20 hours. The software update is easy if you have a Windows 7/10 laptop, Tripp Lite USB to Serial dongle, and a Tech 2 (clones work too). Sent from my iPhone using Tapatalk
