Name: Coolant Temperature Sensor CCS20 22630-51E00 for Holden Commodore VL Calais Barina
Brand: SensorGal
SKU: CCS20-HOL
Price: 49.00 AUD
Availability: InStock

BRAND NEW *OEM Quality* Coolant Temperature Sensor to suit Holden Commodore VL / Calais VL / Barina MB / Rodeo 2.6L and HDT Brock VL.

When your coolant temperature sensor fails the ECU loses its main temperature input - causing hard cold starts, rich fuel mixture, erratic temperature gauge and fault codes P0115 / P0116 or P0117. This is a direct-fit replacement using the original 2-pin green rectangular connector with M12x1.5 thread and includes a replacement gasket/seal. Same-day dispatch from Victoria.

TO SUIT

Holden Commodore VL 3.0L RB30E and RB30ET turbo sedan / wagon (1986-1988) - Holden Calais VL 3.0L RB30E and RB30ET (1986-1988) - HDT Brock VL 3.0L RB30E Special Vehicles (1988) - Holden Rodeo TFR17 / TFS17 2.6L 4ZE1 (1988-1998) - Holden Barina MB 1.3L G13A (1985-1986).

FITMENT CHECK

The Commodore VL and Calais VL use a Nissan RB30 engine - this sensor is the original Nissan-sourced part OEM 22630-51E00. Confirm your VL is fitted with the RB30E or RB30ET engine before ordering. Barina MB G13A suits production from 02/1985 to 08/1986 only.

ABOUT THIS SENSOR

The Coolant Temperature Sensor (CTS) monitors engine coolant temperature and sends a voltage signal back to the ECU. The ECU uses this reading to regulate fuel injection duration, ignition timing, cold start enrichment, idle speed, and cooling fan activation.

The Holden Commodore VL and Calais VL use the Nissan RB30 engine and share the same coolant temperature sensor as the Nissan Skyline / Pintara of the same era. When the sensor fails the ECU loses accurate temperature data causing rich running, hard cold starts, and erratic gauge behaviour.

COMMON SYMPTOMS OF FAILURE

Check engine light on - fault codes P0115 / P0116 / P0117
Temperature gauge stuck, reading high or fluctuating
Engine running rich - excessive fuel consumption
Hard starting when cold - extended cranking required
Rough idle or stalling when engine is cold
Cooling fan not activating or activating late

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.
