Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

On my way back home after a 200 mile trip (mostly highway) at 65-75mph.I was on a secondary road two miles from my house my car had the CEL come on!! I did a code reader at home and got one code P1118. Renntech.org gave it an oxygen sensor heating after TWC bank 2. Anyone have any ideas?? It was a friggin hot day (86F). I reset the code but wanted to check with the forum before I took off again. I have a 2001 C4 just hit 20,000 miles new oil air oil filter about 5000 miles ago. Thanks

POST 2 / ORIGINAL POSTEROriginal post

Anyone have any comments on this??? Anyone?? Is anybody out there??

POST 3Original post

Why are you doubting what you read at Renntech.org? That site is extremely helpful in these situations. BTW, My 2001 C4 had 20,000 miles on it in 2002.. hehe you need to drive it more!

POST 4 / ORIGINAL POSTEROriginal post

I guess my question is. Do i do anything about it? Wait till it thows another code out? Should I bring it to the dealer? Will I damge anything by driving it? I searched the forums but not much info about what the problem may be. Was it a fluke because of the super hot weather.Where is this guy Loren when I need advice??

POST 5Original post

If the CEL comes back you probably need a new O2 sensor or heater (yes, they have heaters so they can measure quickly at start-up).

This is a source reference. Confirm exact model applicability in the original material.
