Even though its a rust bucket I completely fell in love with it! It has a couple of check engine lights that I need some help on fixing. I tried to look them up but im so use to my 02 Monte Carlo ss and I saw these codes and have no clue in hell what they mean lol.

KEY ON CODES
　
31= EVP circuit below minimum voltage.
　
85= Canister Purge (CANP) circuit failure.
KEY ON ENGINE RUNNING CODES
　
21= ECT out of Self-Test range MAP/BARO out of Self-Test range.
　
41= No HO2S switch detected (right HO2S).
　
18= SPOUT circuit open

I have to get all these codes fixed in order to get an inspection sticker lol so I cant drive it at all until they are fixed. Thanks in advance!!!

Welcome to FTE.

Closing the SPOUT circuit would most likely fix many of those codes.

 

May I ask what is a spout circuit? lol
