2013 Nissan Pulsar temperature sensors: what they do and when to service or replace them

Temperature sensors are absolutely fitted to the 2013 Nissan Pulsar and they do plenty of heavy lifting. Technical references that confirm this include the Nissan Electronic Service Manual (ESM) for the C12/B17 series: the Engine Control (EC) section lists the Engine Coolant Temperature (ECT) and Intake Air Temperature (IAT) sensors, the Heater & Air Conditioning control sections list the ambient/outside air temperature sensor, and the Transmission (TM–CVT) section notes a transmission fluid temperature sensor on CVT-equipped cars. These align with standard OBD‑II definitions (SAE J1979) for temperature inputs and related fault codes.

On the Pulsar’s MR18DE or MR16DDT engines, temperature sensors help the ECU judge fuelling, ignition timing, cold-start enrichment, and radiator fan control. The ECT tells the ECU and dash gauge how hot the engine is under the bonnet
