Re: Code 12 Issue
Not knowing what year, I can't tell whether you have 12 pin or 16 pin ALDL connector.
Below article should help with your diagnosing the problem. I can't immagine cam position sensor being related but wheel speed sensor replacement may be related. https://tech.corvettecentral.com/201...trouble-codes/ |
