What is your question?
Check engine light on after transmission swap. Mechanic says he broke an o2 sensor replacing the exhaust but Didn't say which one or where. I want to inspect before bringing it back.
Awesome. To clarify: So The OBD1 version of my van only has 1 O2 sensor? Located before the cat?
Yes , OBDI does not monitor the cat function , and that is all the secondary sensors do.
Did. Only found 1 in front of cat
It is NOT OBDII , so that is IT.
