Dodge Journey Engine Oil Temperature Sensor: A Guide for 2009-2020 Models
Understanding the signs of a failing oil temperature sensor and how to choose the right replacement for your Journey.
- The replacement cost and difficulty depend heavily on your engine; the 3.6L V6 is a major job, while the 2.4L is simple.
- A bad sensor will almost always trigger the check engine light with codes P0197 or P0198.
- For the 3.6L V6, it is highly recommended to also replace the oil cooler housing gaskets to prevent future oil leaks.
- Quality aftermarket brands are a suitable and cost-effective option for this sensor.
Is Your Dodge Journey's Oil Temperature Sensor Failing?
A bad engine oil temperature sensor usually doesn't leave you stranded, but it can cause annoying issues. The most common sign is the check engine light turning on. You might also notice poor acceleration, especially when the engine is cold, or see an incorrect oil temperature reading on your dashboard display. In some cases, it can even trigger a false 'oil change required' message. The sensor sends a voltage signal to your Journey's computer; when this signal is too high or too low, it triggers a fault code and the check engine light.

The location and replacement difficulty for this sensor are completely different depending on which engine your Dodge Journey has. For the 3.6L V6 engine, the sensor is located deep in the 'V' of the engine on the oil cooler housing, underneath the upper and lower intake manifolds. This makes replacement a very labor-intensive job (3-4 hours) that requires removing the entire intake system. For the 2.4L 4-cylinder engine, the job is much simpler. The sensor is typically on the top side of the engine and far more accessible. 🎬 Watch this quick guide to locate and swap the 2.4L sensor. Always confirm your engine type before ordering parts or getting a labor quote.
Choosing the Right Aftermarket Sensor
For a simple electronic part like an oil temperature sensor, a quality aftermarket brand is often a reliable and cost-effective choice compared to the OEM Mopar part. Brands like Standard Ignition (Standard Motor Products) and Walker Products are common, direct-fit replacements. Given the low cost of the part itself, the main factor for 3.6L V6 owners is the high labor cost. Because of this, it's wise to choose a reputable aftermarket brand to avoid having to do the job twice.
Pro Tip for 3.6L V6 Owners
The oil filter/cooler housing on the 3.6L Pentastar engine is a known weak point and often leaks oil. Since a mechanic must remove the intake manifolds to access the temperature sensor, it is highly recommended to replace the oil cooler housing gaskets (or the entire housing, preferably with an upgraded aluminum version) 🎬 See a step-by-step walkthrough of the 3.6L oil cooler replacement. at the same time. This preventative maintenance can save you from a much larger repair bill down the road.

Frequently Asked Questions
Where is the oil temperature sensor located on my Dodge Journey?
On the 3.6L V6, it is on top of the oil cooler assembly, which sits in the valley between the cylinder heads, under the intake manifolds. It is the upper of two sensors; the lower one is the oil pressure sensor. On the 2.4L 4-cylinder, it is more accessible and typically found on the engine block near the intake side.
Can I drive with a bad oil temperature sensor?
Yes, in most cases you can still drive the vehicle. However, the check engine light will stay on, and your engine's computer may not be able to properly adjust performance, potentially leading to sluggishness or poor fuel economy. It's best to get it repaired to avoid any long-term issues.
What happens if I don't replace it?
Ignoring a bad oil temperature sensor means your check engine light will remain on, which could mask other, more serious problems. Your engine may not run optimally, and you won't have an accurate reading of your oil temperature, which is a key indicator of engine health.
Are there any recalls for this part?
No, there are no specific recalls from Dodge or the NHTSA for the engine oil temperature sensor on the 2009-2020 Journey. However, there was a Technical Service Bulletin (TSB 18-034-14 REV. A) for the related oil pressure sensor on some 2013-2014 models, indicating known issues with sensors in this area on the 3.6L engine.
