BRAND NEW *OEM Quality* engine coolant temperature sensor to suit Nissan Navara D21, D22 and D40 petrol and early diesel engines.

If your Navara is running rich, idling poorly when cold, showing a temperature gauge that never settles, or has thrown a P0116-P0118 code, this sensor is the direct OEM replacement to fit. Packed and shipped from Cranbourne VIC.

TO SUIT

Covers the Nissan Navara D21 and D22 running KA24E, KA24DE, TD27, QD32, VG30E and VG33E engines, and the D40 with the 4.0L VQ40DE V6. Also fits the D23 NP300 QR25DE and the Terrano R20 and R50. The sensor threads into a coolant passage in the cylinder head near the thermostat housing.

FITMENT CHECK

This listing does not cover the 2.5L YD25DDTi or the 3.0L ZD30DDT Navara - those engines have their own dedicated listings in our store. Check your engine code before ordering.

ABOUT THIS SENSOR

The engine coolant temperature sensor is a thermistor that changes resistance as coolant temperature rises. The ECU reads that signal to set fuel injection quantity, ignition timing and, on automatics, torque converter lock-up and shift points.

When it fails the ECU loses its temperature reference and defaults to a fixed value, which usually means an over-rich mixture, poor cold starting and higher fuel consumption. On diesel Navaras the same signal tells the glow plug controller when to stop cycling.

COMMON SYMPTOMS OF FAILURE

Hard cold starting or extended cranking
Rough idle until the engine warms
Poor fuel economy or black smoke from the exhaust
Temperature gauge reading incorrectly or not moving
Radiator fans running constantly or not at all

How do I test a coolant temperature sensor?

The most common test is to measure the sensor resistance with a multimeter at a known coolant temperature and compare against the manufacturer resistance curve. A cold engine (20 degrees C) typically reads 2,000 to 3,000 ohms and drops to around 200 to 300 ohms at operating temperature (90 degrees C). An OBD2 scanner showing a fixed temperature reading that does not change as the engine warms up is also a strong indicator of sensor failure.

Can a faulty coolant temperature sensor cause my engine to overheat?

Indirectly yes. If the sensor reports a lower temperature than actual, the ECU may not activate the cooling fan at the correct time, allowing the engine to overheat. It can also suppress the dashboard warning light, meaning you may not be alerted until the engine is already at a dangerously high temperature. Replace a suspected faulty sensor promptly.

Do I need to drain the coolant to replace the sensor?

Not always - many coolant temperature sensors can be replaced quickly with minimal coolant loss if you work fast and have a replacement ready to thread in immediately. However on some vehicles the sensor location requires partial coolant drainage. Check the sensor position on your specific engine before starting. Always use fresh coolant when topping up after replacement.

What are the symptoms of a faulty coolant temperature sensor?

Symptoms include poor fuel economy, black smoke, engine overheating warning, incorrect temperature gauge reading, hard starting when cold, and rough idle. Fault codes P0115 to P0119 are commonly associated with coolant temperature sensor faults.

Is it safe to drive with a bad coolant temperature sensor?

A faulty coolant temperature sensor can cause the ECU to run rich fuel mixtures and prevent the cooling fan from operating correctly, risking engine overheating. Replace it promptly - it is a low-cost part that can prevent expensive engine damage.

How do I know if my coolant temperature sensor or my thermostat is faulty?

A faulty thermostat typically causes the engine to overheat or never reach operating temperature. A faulty coolant temp sensor causes incorrect gauge readings and running issues but the coolant itself may be at the correct temperature. An OBD2 scanner showing live coolant temp data helps distinguish between the two.

Are there two coolant temperature sensors on my vehicle?

Many vehicles have two sensors - one for the ECU (engine management) and one for the dashboard temperature gauge. They look similar but are not interchangeable. Check your vehicle's service manual or contact us with your vehicle details to confirm which sensor you need.
