Diagnostic Aids

A normal engine operating temperature is specified as 176°F (80°C) or more. An intermittent malfunction may be caused by a fault in EGR control system electrical circuits. Inspect EGR wiring and components for an intermittent condition. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 2.0L & 2.5L TRACKER article.
