There are a few hundred different, specific codes.

What is the engine size?
What is the code number?
Where specifically did you measure voltage and what did it read?
Do you have the ability to read data in a scan tool?


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
