Product Function Description

The engine coolant temperature sensor (part number 22630-44B20) is a critical component of your Nissan or Infiniti‘s engine management system. Its primary function is to measure the temperature of the engine coolant and transmit this data to the engine control unit (ECU) via a variable resistance signal. The sensor uses a Negative Temperature Coefficient (NTC) thermistor, meaning its resistance decreases as coolant temperature rises. The ECU uses this signal to calculate critical parameters including fuel injection quantity and timing, ignition timing, variable valve timing, and automatic transmission shift strategy. On YD25 common-rail diesel engines, the ECU also uses this signal to control the glow plug controller . For compatible Nissan, Infiniti vehicles, a properly functioning coolant temperature sensor is essential for cold-start performance, fuel efficiency, and overall engine reliability.


DIY Diagnosis Guide

How to Tell If Your Coolant Temperature Sensor Needs Replacement:

Look for these common signs:

  1. Check engine light (P0115-P0118) – Codes related to coolant temperature circuit

  2. Hard starting when cold – ECU receives incorrect temperature signal

  3. Poor fuel economy – Incorrect fuel mixture due to faulty temperature data

  4. Cooling fan runs constantly or not at all – Fan operation affected by sensor signal

  5. Temperature gauge malfunction – Erratic or non-working gauge
