    Yes 

    1. Go To  2.

    No 

    1. If the DTC is stored, check for an intermittent condition. Using the wiring diagram/schematic as a guide, visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
  2. DETERMINE ENGINE SIZE 

    Is this vehicle equipped with a 3.7L or 6.1L engine? 

    Yes 

    1. Go To  3.

    No 

    1. Go To  6.
