Exhaust Gas Temperature Sensor (CALIF Models) Test
- Measure resistance across sensor terminals. Place exhaust gas temperature sensor in container of water. Sensor resistance should decrease as temperature increases.
- 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 will be set in ECU memory. If a Code 35 is set, proceed to TESTS W/CODES article.
