Coolant temperature should be higher than intake air temperature at warm idle.
If coolant temperature is below 40℃ (104℉), not engine stalling but high engine RPM could be detected.
Check if there is a big difference between "Coolant Temperature sensor" and "Intake Air Temperature sensor" after engine warming up.
■ Specification : At initial starting, coolant temperature sensor is similar to intake air temperature sensor.
Is the ECTS data normal?
 | ▶ Go to "Fuel supply state inspection" procedure. |
 | ▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. ▶ Check for open circuit in the ECTS circuit. ▶ Check for short to ground in the ECTS circuit. ▶Substitute with a known-good ECTS and check for proper operation. If the problem is corrected, Replace the ECTS. |
