So you think 1884 was related to the O2 sensor fault codes?

 

It was related to the combination of codes you once have. You will probably see it again for any of a number of other issues. It is not a code to worry about, the other codes that are with it are always the issue.

 

Good info...thanks!

 

What may have happened is a control unit made a phone on the can line and no one answered. If that control unit keeps calling and other control units do not answer, then it can bring down the can line and cause all kinds of faults. That's why new cars do use a can line system like this anymore.

 

When you don't know for sure what you are talking about, listen to the others and learn. The 1884 never comes up by itself, as already mentioned. It comes up with another code which is the real issue and when that code is resolved, the 1884 goes away on it's own.

 

1884 is a non circuit pacific code. The vehicle cannot have all of those faults stored related to that code. Something took the can line down. Can it be other faults of course or a control unit. That's we newer cars use Ethernet system, not control area net work system anymore.
