Electrical Connections or Wiring

WARNING: This page is about a different car, the 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

Electrical connections and wiring cause most intermittent conditions. Determine which circuit is suspected of having an intermittent condition. This may be indicated by DTCs with a fault not present. Check the suspect circuit for the following conditions:

Connectors poorly mated.
Terminals not fully seated or backed out in the connector.
Terminals not properly formed or damaged, usually due to improper diagnostic probing procedures.
Poor terminal retention. Testing for terminal retention requires the use of the Terminal Repair Kit (J 38125 C), or equivalent.
Poor terminal to wire connection. Inspecting for poor terminal to wire connection requires removing the wire/terminal from the connector body.

Repair the components as necessary.
