Coolant Sensor for Dodge Journey Nitro Challenger Freemont 5149077AA

BRAND NEW *OEM Quality* coolant temperature sensor to suit Dodge Journey, Fiat Freemont, Chrysler Grand Voyager, Dodge Nitro and Dodge Challenger petrol engines.

A failed coolant temperature sensor can trigger inaccurate engine temperature readings, poor fuel economy, or an illuminated check engine light. Dispatched same-day from Cranbourne VIC.

TO SUIT

Dodge Journey JC 3.6L (2011-2016), AWD and FWD
Fiat Freemont JC 3.6L (2011-2016) - the rebadged Journey sold new in Australia
Chrysler Grand Voyager RT MPV 3.8L (2007-2011)
Dodge Nitro 3.7L V6 4WD (2007-2012)
Dodge Challenger SRT8 and Scat Pack 392 6.4L (2011-2023, RHD-converted)

FITMENT CHECK

On the 3.6L Pentastar (ERB) Journey and Freemont, this coolant sensor location is separate from the oil temperature sensor - they are not interchangeable. Confirm your engine bay position before ordering.

ABOUT THIS SENSOR

The coolant temperature sensor measures engine coolant temperature and reports it to the ECU, which uses this reading to control fuel mixture, ignition timing, cooling fan operation and the dash temperature gauge. This part covers five different nameplates across three brands, sharing the same Chrysler-group sensor location and thread across MPV, SUV and coupe body styles.

On the low-volume Freemont and RHD-converted Challenger, sourcing this part locally rather than through a dealer parts department is usually the faster and cheaper option.

COMMON SYMPTOMS OF FAILURE

Check engine light illuminated (fault codes P0115-P0118)
Inaccurate or erratic temperature gauge reading
Cooling fan running constantly or not at all
Poor fuel economy or rough cold-start idle
Engine running rich or lean
Black smoke from exhaust on startup

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.
