Pulled codes...what do they mean?

[Hethj7]

I pulled these codes today in the KOEO test:

Hard code:

67 - Manual lever position sensor out of range, neutral pressure switch switch circuit open ( my car is a 5 speed)

Continuous memory codes:

31 - EVP or PFE circuit below minimum voltage

66 - TOT sensor signal input below self-test minimum or vane air flow circuit below minimum

96 - Fuel pump secondary circuit fault, high speed fuel pump relay open

I don't know why code 67 would matter much and am not sure what would cause the code 96. What is the EVP or PFE circuit and what is a TOT sensor? Where do I go from here? Thanks!
