2C3F??

I just got this code after cleaning my valves. I had to lengthen the wiring harness that goes to the TMAP sensor because i was not able to get that black box that attaches to the bottom of the manifold, back where it was. So I thought this was related to my splice of the tmap harness, but when I start the car with it completely unplugged, I get a whole slew of new codes.

Assuming it's not the tmap sensor, and the cars runs fine with this one code, what do you think it could be?

P2C3F Internal ECU error; lambda evaluation module ...
