RE: Can't Clear Code.
A small leak will drive you insane.
Keep in mind, a cracked hose on the EVAP system can trigger a LARGE leak, so to find a small leak will require lots of luck.
Even using pressurized smoke in the system, they are very very difficult to find.
Give up on the gas cap. - Yes they can cause a leak.
But that is always everybodys answer, there are many other parts that can cause it too. And a gas cap would likely not be a small leak.

RE: Can't Clear Code.
yeah but it's always a cheep place to start (gas cap)
Also if you think about it, it is the only part in the system that gets removed and replaced often so it would make sense to start there.

I have looked for a good place to post my problem, unfortunately, there just isn't one.
At 160k miles my 99 Dak had a rear cam bearing go out. I put in a brand new long block.
When it was fired up it gave two error code readings.
One was the Engine Coolant air sensor. That was replaced, code cleared and no problem. Deleted the code out and it went away.
The second was 0118, engine temp sensor.
Bought a new one and replaced the old one. Deleted the code and started the engine. The code came right back.
Checked the plug in, checked for shorts, checked for everything including even the cluster to see if a wire had been bumped somehow and loosened.
Deleted the code, cranked the truck and it came right back to the 118 code.
OK..reset the comp, deleted the code. Restart the truck and the check engine light comes on again, the error code is back.
I am optimistic, I have bought bad parts brand new before. So I bought a new Mopar sensor, installed it, reset the computer and deleted the error code with the reader.
Cranked it up and the check engine light comes on.
We deleted the code once more, checked all connections, reset the computer by removoing the ground cable, no good. Reset by removing the fuel pump fuse in the control block. No good...I used every possible combination's of resetting the computer known to those of us who are mechanically challanged. Except in this case, my certified mechanic that has done work for me for years and has always been on top of everything is baffled.
The really strange part is this. When you start the engine and let it warm up, then shut it off, you can switch the key to the /ON position and the temp gauge works fine and the CE light goes off.
Crank the engine and the CE light comes on and the gauge drops to zero.
Is there a magician out there with an answer to this phenomenon?
I have already poured gas on this truck twice, but my wife wouldn't let me light it.
