Installation only took me 5 min, and here are the steps I used:
1. Parked my car so that the middle of the vehicle is where your drive way and the street meet. Usually there's a dip there like at my house, this gave me an extra 3-4" to crawl underneath the vehicle.
2. Remove the gray plug using a flat screwdriver. Insert the flat head at the top of the plug and pull, it should come off easy.
3. Spray some WD40 or liquid wrench on the nut part of the sensor, and let sit a few min.
4. Remove sensor using a crescent wrench
5. Install new part and tighten with wrench, replug the plug and you are done!
I started the engine and no check engine light or traction control lights! A few reviews said it takes a while for the lights to go off so I might have gotten luck. I hope this helps someone.
My mechanic told me he could install it for $100. The cost here was $45. When I opened it up it looked pretty straight forward to install so I slid under the truck and had it installed in less than 10 mins. Check engine light cleared itself and a few months later we're still good to go! Saved over $100 on the part and I kept the $100 in labor in my pocket as well.
Just a side note, you can have the check engine light cleared with an OBD reader or just wait and it will clear itself. It may take a few days of driving, it more than likely won't clear just taking it around the block. The vehicle runs diagnostics on itself periodically and when it does, if it's installed right, it will clear the code on its own. Mine took 2-3 days of driving (about 3-4 hours of driving).
For those who are replacing themselves, please be prepared for a bit of effort to remove the old sensor. I soaked mine in PB Blaster numerous times over several days but still it wouldn't budge with a quality crowfoot and breaker bar. I finally used a dremel to cut the collar of the old sensor off, then placed a deep-set impact socket on the sensor. I used an impact u-joint and an extension to get my impact wrench in there to try to loosen the hold. This still didn't take it off. I let the sensor soak overnight in PB blaster again, then tried the same socket with an extra long breaker bar (I think the spring of the u-joint may be taking too much of the impact). Voila! got the beast loose! I drive my rig on the beach and in mud and snow so I wasn't shocked that it didn't want to come loose. All I can say is be prepared to be *very* persistent with the old sensor!
