Unknown Ground Strap
OK, took the covers off and looked for any issues. First thing I see is this ground strap stairing me in the face. Mechanic had worked on the PVC hose and this ground was right under it. Mechanic said that he did not remove any grounds. We went to look at the temp sensor and found that the clip had broken, and he got a code of P0118.
He just called and said the temp sensor has been replaced and everything seems fine. My concern is that groud strap. I know grounds can have strange effects on the C5 and he had no idea where it was supposed to go.
Here's the previous post with the issue that started this:
Just got my 2000 Roadster out of the shop today for California smog issues. State certified shop replaced PVC hose and Catalytic converters. Car was running fine and passed the emission portion of the tests but check light was on and code P0430 (TWC System Low Efficiency Bank 2) was in the DIC. Today when I got the car back everything seemed fine and I took off on a 100 mile round trip appointment. In traffic on freeway noticed temp gauge was very erratic fluctuating from 172 to 212. Everything else seemed fine and I continued to my stop.
Coming back things began to get worse. Temp gauge was becoming more erratic and was actually pegging zero. As it dropped the rpms began fluctuating and I thought I was going to have a low power situation. I made it home but as I was backing into driveway car stalled and would not restart with five tries. Went inside to get a flashlight and then tried again and it started but with very erratic idle. All other gauges seemed fine.
Pulled codes and this is what I have:
10-PCM P1431 H
40-BCM B0503 H
58-SDM B1001 H
AO-LDCM U1064
A1-RDCM U1064 H
A6-SCM B0851 H
B2172 H C
B2177 H C
I have a suspicion that something may not have been connected correctly, but nothing to prove that.
Your help would be much appreciated.
Thanks in advance

Thanks
Got the car back today and it was a bad Temp Sensor. Showing the mechanic the diagram he finally admited that it was indeed to be attached to the PVC valve. He wouldn't agree that it was important or could lead to problems. Cars running fine put 40 miles on today and will put 110 on tomorrow. Keeping my fingers crossed and AAA card in hand.
Again thanks for the help!
