TEST CONDITIONS

Pin voltage (values) are obtained using scan tool connected to Data Link Connector (DLC). The following conditions must be met before testing

  1. Engine at normal operating temperature.
  2. Engine at idle (closed throttle).
  3. Transmission in Park or Neutral.
  4. Accessories off.
  5. A/C system off.
  6. Closed-loop operation.
