DA1 - Check ECT or IAT Sensor

Diagnostic Trouble Code (DTC) 116 Engine Coolant Temperature (ECT) or 114 Intake Air Temperature (IAT) indicates that the corresponding sensor is out of Self-Test range. Correct range of measure is 0.3 to 3.7 volts.

Possible causes:
- Low coolant level (ECT).

- Ambient temperature below 10°C (50°F) (IAT).

- Faulty harness connector.

- Faulty sensor.

- Run engine for two minutes at 2000 rpm.

NOTE: For Tempo/Topaz vehicles with DTC 114 (IAT), additional warm uptime may be required due to IAT sensor location. Run engine until under hood temperatures are warm and stabilized.

For No Starts:

- Go to DA3. DA3 - Check Resistance of Temperature Sensor - Engine Off

For vehicle stalls:

- Go to S1. S - System Check

- Check that upper radiator hose is hot and pressurized.

- Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)

- Is DTC 114 or 116 present?

Yes -- Go to DA2. DA2 - Check VREF Circuit Voltage At Throttle Position Sensor

No -- Service other DTCs as necessary.
