BRAND NEW *OEM Quality* coolant temperature sensor to suit Honda Jazz GE GF GK GP 1.3L 1.5L hatchbacks.

A worn coolant sensor on the Jazz shows up as rough idle, poor economy or an erratic temp gauge - this direct-fit replacement restores accurate readings on both manual and CVT models. Dispatched same-day from Cranbourne VIC.

TO SUIT

Suits the Honda Jazz GE 1.3L and 1.5L i-VTEC (2008-2014), the GE,GG,GP 1.3L Hybrid (2011-2014), and the GF,GK 1.5L (2014-2023).

ABOUT THIS SENSOR

On CVT-equipped Jazz GK models the ECU uses coolant temperature as part of the transmission's warm-up shift mapping, so a drifting sensor can affect CVT behaviour as well as fuel trim and idle quality.

On the GE,GG,GP 1.3L Hybrid the same reading also feeds the IMA system's thermal management, meaning a fault can reduce hybrid assist in addition to the usual engine symptoms.

COMMON SYMPTOMS OF FAILURE

Rough idle or hard starting when cold
Poor fuel economy or excessive fuel consumption
Black smoke from the exhaust (engine running rich)
Engine overheating or cooling fan running constantly
Check Engine Light with fault code P0116, P0117 or P0118
Incorrect or fluctuating temperature gauge reading
GK CVT models: harsh or delayed shifts during warm-up
GP Hybrid: reduced IMA electric assist

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.
