BRAND NEW *OEM Quality* Engine Coolant Temperature Sensor to suit BMW 3 Series E30 E36 E46 E90 E91 E92 E93 1987-2018.

The 3 Series is BMW's highest-volume model on Australian roads, and this sensor is one of the most common coolant system failures reported across the range. A worn sensor sends the ECU an inaccurate coolant reading, throwing the fuel mixture off and often triggering an engine warning light.

TO SUIT

Fits BMW 3 Series sedan, coupe, convertible and touring models built from 1987 to 2018, spanning the E30, E36, E46, E90, E91, E92, E93 and F30 chassis across four-cylinder and six-cylinder petrol engines.

PACKAGE INCLUDES

1 x OEM Quality Engine Coolant Temperature Sensor (2-pin connector, with seal ring).

ABOUT THIS SENSOR

The 3 Series coolant temperature sensor sits in the lower radiator hose and reports coolant temperature to the ECU, which uses that reading to manage fuel trim, ignition timing and the electric cooling fan.

A failing sensor is a common cause of erratic temperature gauge readings and rough idle on the E46 and E9x generations in particular, and is cheap insurance against a bigger cooling system failure down the track.

COMMON SYMPTOMS OF FAILURE

Check engine light with a P0115-P0118 fault code
Temperature gauge reading incorrectly or fluctuating
Engine running rich or lean, poor fuel economy
Cooling fan running constantly or not at all
Difficulty starting when cold

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.
