Michael,
I assume you had the engine running because T1 and T2 show zero when the engine is off but you will see CHTs when the engine is off.
I had several issues with my VM1000. Reggie Smith was always able to fix it: mooney37v@juno.com

Subject: VM 1000 question
Hello there,
I am looking for some advice. I had the plane (TSIO 550) out of annual about 15 minutes into the air and the TIT 1, TIT 2 and P temps on the VM1000 all read 0000. The EGTs and the CHTs on all cylinders work fine as do the engine instruments. I don’t think this sounds like a single probe failure, but why that pattern? Any ideas would be appreciated. The local avionics shop isn’t up to speed and before I get it torn apart, if someone had this experience, I’d appreciate hearing about what you did.
The unit is 12 years old and has 1200TT.
Michael Smith
