BRAND NEW *OEM Quality* coolant temperature sensor to suit Nissan Patrol Y61 GU with TD42 4.2L diesel, ZD30 3.0L diesel, TB45 4.5L petrol, and TB48 4.8L petrol engines.

A failing coolant temp sensor on the Patrol GU commonly triggers limp mode on ZD30 engines, causes erratic temperature gauge readings on TD42 variants, and forces the glow plug controller to run glow plugs beyond their normal cycle on diesel engines. Direct plug-in replacement - no wiring modification needed. Same-day dispatch from Cranbourne VIC.

TO SUIT

Suits Nissan Patrol Y61 GU (1997-2016) across all engine variants - TD42 4.2L diesel (1997-2006), ZD30DDTi 3.0L turbo diesel (2000-2016), TB45E 4.5L petrol (1997-2001), and TB48DE 4.8L petrol (2001-2012). Also suits Nissan Patrol GQ with TD42 engines produced after August 1995 and Nissan Patrol Y62 with the VK56 5.6L V8 petrol engine - refer to the full compatibility list below.

FITMENT CHECK

Early GQ TD42 engines produced before August 1995 use a different sensor with a different connector. Confirm your sensor has the correct 2-pin plug before ordering. This listing suits the later GQ TD42 (post-Aug 1995) and all GU TD42 engines only.

ABOUT THIS SENSOR

The coolant temperature sensor measures engine coolant temperature and sends a voltage signal to the ECU. On Nissan Patrol diesel engines this sensor also signals the glow plug controller - a failed or inaccurate sensor causes glow plugs to operate outside their normal cycle, contributing to hard cold starts on TD42 and ZD30 engines. On petrol variants (TB45 and TB48) the sensor controls fuel injection enrichment, ignition timing, and cooling fan activation across the full operating range.

COMMON SYMPTOMS OF FAILURE

Check engine light with fault codes P0115 / P0116 / P0117 / P0118
Temperature gauge reading erratically or stuck at cold
ZD30 entering limp mode with temperature-related fault codes
Glow plugs not cycling correctly - hard cold starts on TD42 and ZD30
Increased fuel consumption - running rich when warm
Cooling fan running constantly

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.
