Parts for your 2016 Nissan Serena-Temperature sensors

2016 Nissan Serena temperature-sensors

Yes, the 2016 Nissan Serena does use temperature sensors. The Nissan Electronic Service Manual for C26/C27 models (Engine Control System and HVAC sections), Nissan FAST parts catalogue, and Jatco CVT technical notes all reference multiple temperature sensors fitted to this vehicle. These include the engine coolant temperature (ECT) sensor, intake air temperature (IAT) sensor integrated in the MAF, ambient air temperature sensor for the climate control, and a CVT fluid temperature sensor within the transmission.

On the Serena, temperature sensors are essential for smooth running and longevity. The ECT sensor tells the ECU how hot the engine is so it can manage fuel, ignition timing, idle speed, and radiator fan operation. The IAT helps with fuelling corrections and throttle response. The ambient sensor keeps the A/C behaving properly, while the CVT temperature input protects the transmission from overheating and adjusts line pressure and shift strategy.

• Engine Coolant Temperature (ECT): Typically threaded into the coolant passage near the thermostat housing or cylinder head water outlet.
• Intake Air Temperature (IAT): Incorporated in the MAF on MR20DD engines.
• Ambient Temperature: Mounted forward of the radiator, behind the front bumper.
• CVT Fluid Temperature: Internal to the Jatco CVT unit.

They’re not a regular “replace by kilometres” service item, but they do benefit from basic care during scheduled servicing. A quick scan-tool check on a cold engine should show ECT and IAT close to outside ambient
