Didn't have any problem with lines in way,just the heat shield. Probably varies with vehicle.When I removed the little screen filter and held it to light it was partially blocked. Cleaned it with brake cleaner and was clear then.

No more dancing oil gauge, DIC doesn't tell me to STOP ENGINE, V8 to V4 fuel management feature works again and Check Engine Light went off!

I found it easier to put rachet assembly on in stages; I put the socket/uni joint/ext together and was able to put that on the switch, then added 2nd ext and finally the articulating rachet.

When I disconnected the wired plug, it's rubber seal stayed in the bad switch, I had to take it out of the switch and put it on the plug before plugging it into the new switch.

After all was said and done, the ordeal was worthwhile as I saved over $300; I might feel differently had I not been able to find and retrieve the dropped switch and socket!

Took the following photos to try to help others who are considering the task,

1) Heat shield on 07's have no bolts. Just lift and wiggle out.
Attachment 10973

2) 07's have another heat shield at the back of the engine.
Attachment 10974

3) Switch is barely visible through a hole at the bottom of the heat shield.
Attachment 10975

4) Photo of switch behind the heat shield.
Attachment 10976

5) Position of socket/universal joint/extension/extension/rachet.
Attachment 10977

6) Photo of socket on switch.
Attachment 10978

Good luck to those who will give this a try.
Hi, I am new to the forum; Hopefully, I can get some advice on this website.
I need to replace the oil pressure sensor on my avalanche. Yesterday, I spent about 3 hours and couldn't get the sensor out. I ended up cutting some of the heat shield located in front of sensor to have better access; Although I still don't have enough room to.reach the sensor, now I can reach it better but can't remove the connector that plugs into the sensor. Picture #4 shows full access to the sensor. How were you able to have much room like that? How did you moved the heat shield.

This required loosening three 5/16 screws (one on intake cover and two clamps on air intake) and four screws (air cleaner cover). These were removed to ensure they weren't cracked as I laid across engine to reach back of engine on the drivers side (right side) to remove the sensor. Location is directly under firewall before back of engine meets the transmission. I used a 3/4" drive, two 6" 3/4" extensions, swivel, and a Autozone Oil pressure sensor socket #25254 to remove the sensor. I will try and add pictures for location and to show what I removed. Took 15min max and corrected the issue with the oil pressure guage jumping around and chiming. Hopefully this will help
Pictures as promised:

Air intake (from air cleaner to throttle body - two 5/16 clamp screws and 4 air cleaner screws:<O></O>

Driver, extensions, swivel, and socket:<O></O>


Location of sensor when laying on top of engine towards windshield:<O></O>


Another view:<O></O>
the odd part here is your vehicle does not have the sound or heat shield that sits exactly where you inserted the socket thru an issue i encountered doing mine.

any advice as to what sealant is needed? Did mine this past weekend and truck is now leaking oil. Also is the heat shield needed or can it be cut away or removed?
