The number of coolant sensors in a vehicle can vary depending on the make and model. Typically, most vehicles have at least one coolant temperature sensor, which monitors the temperature of the engine coolant. Some vehicles may have additional sensors, such as a low coolant level sensor or multiple temperature sensors for different engine components. Always refer to the specific vehicle's service manual for accurate information.

Modern vehicles are equipped with multiple temperature sensors. They are used to advise the engine computer and driver on the condition of the vehicle systems. Common automotive temperature sensors include coolant, transmission, ambient air temperature and engine oil.
The 2001 Pontiac Grand Prix GTP typically has two coolant temperature sensors. One is located in the engine block, which provides data to the engine control module (ECM) for engine management, while the other is usually located in the thermostat housing and is used for the temperature gauge on the dashboard. These sensors help monitor the engine's temperature for optimal performance and efficiency.

The OBD2 code P0128 for a Saturn SC1 indicates a problem with the engine coolant temperature being below the thermostat regulating temperature. This could be caused by a faulty thermostat, low coolant level, or a malfunctioning coolant temperature sensor. It is important to diagnose and address the issue to prevent damage to the engine.
No, not all coolant temperature sensors are the same. They can vary in design, specifications, and compatibility depending on the make and model of the vehicle. Different sensors may have varying resistance characteristics and connector types, which means it's essential to use the correct sensor for a specific engine to ensure accurate temperature readings and proper engine performance.
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
The temperature in an engine is primarily regulated by the cooling system, which includes components like the radiator, water pump, thermostat, and coolant. The thermostat controls the flow of coolant to maintain optimal operating temperature, while the water pump circulates coolant through the engine and radiator. Additionally, engine oil helps dissipate heat, and sensors monitor temperature to ensure the engine operates efficiently and prevent overheating.
