Test NTC-4A - Checking Coolant Sensor Calibration & Radiator Fan Operation

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: After each repair, perform TEST VER-2 .

Start engine. Allow engine to reach normal operating temperature. Using DRB, read Engine Coolant Temperature (ECT) sensor value. If ECT sensor value does not increase smoothly, replace ECT sensor. If ECT sensor value increases smoothly, go to next step.
If coolant temperature reaches 180°F (82°C) or more, replace ECT sensor. If coolant temperature does not reach 180°F (82°C), or more, go to next step.
Run engine until radiator fan operates or temperature reaches 220°F (104°C). If cooling fan does not operate, repair cooling fan as necessary. See SPECIFICATIONS article in the ENGINE PERFORMANCE section and ENGINE COOLING FAN article in the ENGINE COOLING section. If cooling fan operates, test is complete.
