Where is the water temperature sensor of Nissan Livina located?
3 Answers
Nissan Livina's water temperature sensor is located next to the thermostat, installed on the aluminum upper water pipe on the right side of the cylinder head, near the transmission. Functions of Nissan Livina's water temperature sensor: It transmits the engine's water temperature signal to the computer and the temperature gauge, and some are also used to control the operation of the fan motor. The water temperature sensor converts the coolant temperature into an electrical signal; after input to the ECU, it adjusts the fuel injection amount—increasing fuel injection at low temperatures; it modifies the ignition timing—advancing it at low temperatures and retarding it at high temperatures to prevent knocking; it affects the idle control valve—at low temperatures, the ECU controls the idle control valve based on the water temperature sensor signal to increase engine speed; it also influences the EGR valve. Precautions: If a warning indicator appears, promptly troubleshoot the issue and pay attention to monitoring the dynamic information on the instrument panel.
I've been driving a Nissan Livina for several years and have replaced the coolant temperature sensor twice. It's located on top of the engine cylinder head, near the thermostat and radiator hose connection. You can easily spot it when opening the hood - it's a thumb-sized plastic component with an electrical connector. Last time when my temperature gauge acted up, I checked and found it positioned at the corner of the left cylinder head. After removing the protective cover, it unscrewed easily. DIY replacement requires caution - avoid getting coolant spray everywhere (I ended up with greasy hands on my first attempt). This sensor monitors engine temperature - failure can lead to overheating and engine damage. If you notice abnormal temperature readings, first check for loose connections by unplugging it. When in doubt, visit a professional repair shop to avoid unnecessary expenses.
When working on car repairs, I often encounter issues with the coolant temperature sensor. On the Nissan Livina, it's usually located on the side or top of the engine cylinder head, near the cooling system interface. It's quite easy to find—just open the engine hood and trace along the radiator hose. You'll see a small black box connected to wires—that's it. Remember to test it with a multimeter first. If the resistance value fluctuates, the sensor might be faulty, causing inaccurate coolant temperature readings. The first time I repaired a Livina, the sensor was in the cylinder head area, similar to most Japanese cars, but the exact position may vary slightly depending on the model year. This component monitors coolant temperature, so regularly clean the surrounding dust to avoid false readings. If you're unsure about the location, check the owner’s manual or take a photo and ask fellow car enthusiasts. Avoid disassembling blindly—damaging the engine would be even more troublesome.
