P0128 2011 Nissan Rogue Code - Thermostat Function

Quick Answer

The P0128 diagnostic trouble code (DTC) in a 2011 Nissan Rogue indicates that the engine coolant temperature is below the thermostat regulating temperature. Common causes include Faulty Thermostat: The most common cause of the P0128 code is a malfunctioning thermostat that is stuck open, preventing the engine from reaching the desired temperature, Low Coolant Level: Insufficient coolant in the system can also trigger this code as there may not be enough coolant to reach the thermostat, Coolant Leaks: Leaks in the cooling system can lead to a loss of coolant, affecting the thermostat's ability to regulate temperature. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0128 2011 Nissan Rogue Description

The P0128 diagnostic trouble code (DTC) in a 2011 Nissan Rogue indicates that the engine coolant temperature is below the thermostat regulating temperature. This code is specifically related to the thermostat function in the vehicle. The thermostat is a crucial component of the engine cooling system that regulates the flow of coolant to maintain the engine operating temperature within the optimal range. When the engine is cold, the thermostat remains closed to allow the engine to warm up quickly. Once the engine reaches the designated temperature, the thermostat opens to allow coolant to circulate and maintain the temperature.

  2. Engine Running Cold: The engine may take longer than usual to warm up, or it may not reach the normal operating temperature.
  3. Poor Fuel Efficiency: A faulty thermostat can cause the engine to run rich, leading to decreased fuel efficiency.
  4. Overheating: In some cases, a malfunctioning thermostat can cause the engine to overheat due to improper coolant circulation.
  5. Heater Malfunction: The vehicle's heater may not produce sufficient heat if the engine is not reaching the proper temperature.
