EGR Temperature Sensor (CALIFORNIA)

  1. Measure resistance across sensor terminals. Place exhaust gas temperature sensor in container of water. Sensor resistance should decrease as temperature increases.
  2. Heat water until boiling temperature of 212°F (100°C) has been obtained. Resistance at 212°F (100°C) should be 76,770-93,830 ohms. If a fault is present in exhaust temperature sensor circuit, a Code 35 may be set in ECM memory. If a Code 35 is set, proceed to TESTS W/CODES article in the ENGINE PERFORMANCE Section.
