interesting, a malfunction of the malfunction lol
does the cel light up when you turn the key to run but have not started it yet?

Yes...cel light ON when you turn the key.
But Now it goes OUT when started, as normal.
What's going on?
Been out for 3 days now ?!?!?!?
UPDATE: the cel is now BACK ON !!!!!

You have an issue with the circuit that illuminates the check engine light. Bad connection on the cluster, wiring, etc.

try a different scanner to see if you get the same code

Found an additional code (P0160). Replaced Oxygen sensor. CEL now out.
HOWEVER - discovered this: key to ON CEL is on. Start car CEL goes off. BUTT...if you very quickly stop and then key to ON = no CEL. Turn off, wait 5 seconds and to ON = CEL ON. Almost like something is resetting?!?!?
Would someone try this: Start your car so CEL goes out. Very quickly turn off and then to ON. Did your CEL immediately come on?
