Visual Inspection

WARNING: This page is about a different car, the 2002 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

Most engine control system driveability problems result from faulty wiring, poor electrical connections, improper wire routing, or leaking air and vacuum hose connections. Inspect all engine control system components, hoses, connectors and wiring for damage before proceeding with self-diagnostics. DTCs can only be retrieved by using a scan tool. See RETRIEVING DIAGNOSTIC TROUBLE CODES .
