Default ECT help.

Just did a head and cam swap. Now i cannot read ECT when tuning, it reads
-38 all the time. I changed the sensor out with a new one and same thing. The gauge on the dash is acting alil weird as well. Sometimes it reads and sometimes it does not... Any help on what else i can try??

Sounds like an open circuit somewhere...I'd check for that. Is the PCM ground at the back of the LH cylinder head tight?
