There is no code, means little challenging.
Remove the coolant sensor. Mesure it resistance.
Get a glass to water with ice in it, plunge it tip in it, mesure the resistance to see if it change. No change in resistance meant the coolant sensor is deffectiv.
Remember, the ECM/PCM monitors various engine and vehicle conditions to calculate the fuel delivery time (pulse width) of the injector(s). The fuel pulse may be modified by the ECM/PCM to account for special operating conditions, such as cranking, cold starting, altitude, acceleration, and deceleration.
A bad coolant sensor could cause the problem. Let me know what you find.
