Component Testing
- Measure and record the resistance of the ECT sensor at various ambient temperatures, then compare those measurements to the Temperature Versus Resistance table.
- Measure and record the resistance of the IAT sensor at various ambient temperatures, then compare those measurements to the Temperature Versus Resistance table.
- Remove the AAT sensor and allow it to rest on a workbench away from sunlight and any direct heat or cold source. Connect the DMM to the sensor, and measure the resistance at an ambient temperature of 22-23°C (72-73°F). The resistance should measure between 4.9-5.4K ohms.
