OBDI Code 11

So, I have this code.

It's listed as Switch Signal, and ECU/ECM.

What in the world could this mean?

Thanks,
Alex

Loss of power supply to ECU through either the ignition circuit or the main relay circuit direct from the battery.

What seems to be the symptom/s you are dealing with?

You should also read through this thread.

Same code from that era OBDI system, the 88 3VZE(no code 11 for later models). The code description is identical for both engines(3VZE & 22RE/RTE). So it may be of some help in finding what's causing your code 11 conundrum.

Good luck!

No, I haven't gotten to my VSS yet, if your curious.

Yes, I still have code 11 syndrome!
