Joseph Weaver Are you experiencing issues with your Subaru’s TPMS sensor? If so, it may be time for a replacement. The good news is that installing a new TPMS sensor on your Subaru is a relatively straightforward process. In this article, we’ll provide you with a step-by-step guide on how to install a TPMS sensor on your Subaru.
Key Takeaways
- TPMS sensors are responsible for monitoring the air pressure in your vehicle’s tires.
- A faulty TPMS sensor can cause your vehicle’s tire pressure warning light to illuminate.
- Installing a new TPMS sensor on your Subaru is a simple process that can be done at home with the right tools and knowledge.
What is a TPMS Sensor?
TPMS stands for Tire Pressure Monitoring System. A TPMS sensor is a small device that is installed inside each tire on your vehicle. The sensor is responsible for monitoring the air pressure in your tires and transmitting that information to your vehicle’s onboard computer.
If the air pressure in one or more of your tires drops below a certain threshold, your vehicle’s TPMS system will alert you by illuminating a warning light on your dashboard. This warning light is typically shaped like a tire with an exclamation point inside.
A faulty TPMS sensor can cause your vehicle’s tire pressure warning light to illuminate even when the air pressure in your tires is normal. If this is the case, it’s important to replace the faulty sensor as soon as possible to ensure accurate monitoring of your tire pressure.
Tools Needed
To install a TPMS sensor on your Subaru, you will need the following tools:
- A TPMS sensor replacement kit
- A valve core removal tool
- A torque wrench
- A jack and jack stands (if necessary)
Step-by-Step Guide to Installing a TPMS Sensor on Your Subaru
-
Determine which TPMS sensor needs to be replaced. If you’re not sure, refer to your vehicle’s owner’s manual or consult with a mechanic.
-
Remove the valve cap from the tire that contains the faulty TPMS sensor.
-
Use a valve core removal tool to remove the valve core from the valve stem.
-
Remove the old TPMS sensor from the valve stem. Depending on your vehicle’s model, the sensor may be attached to the valve stem with a screw or a nut. Use a suitable tool to loosen and remove the sensor.
-
Install the new TPMS sensor onto the valve stem. Make sure that it is properly aligned and tightened according to the manufacturer’s instructions.
-
Install the valve core back into the valve stem.
-
Inflate the tire to the recommended air pressure for your vehicle.
-
Repeat steps 2-7 for any additional TPMS sensors that need to be replaced.
-
Use a torque wrench to tighten the valve cores to the manufacturer’s specifications. Over-tightening can cause damage to the valve stem or sensor, while under-tightening can cause air leaks.
-
Once all TPMS sensors have been replaced and tightened to the proper torque specifications, reset your vehicle’s TPMS system by following the instructions in your owner’s manual.
-
Test your TPMS system by driving your vehicle for a short distance. If the tire pressure warning light does not illuminate, your new TPMS sensors have been installed correctly.
FAQ
How much does it cost to replace a TPMS sensor on a Subaru?
The cost of replacing a TPMS sensor on a Subaru varies depending on the model and year of your vehicle. On average, you can expect to pay anywhere from $50 to $200 per sensor.
Can I replace TPMS sensors myself?
Yes, you can replace TPMS sensors yourself as long as you have the proper tools and knowledge. However, if you’re not comfortable working on your own vehicle, it’s best to consult with a mechanic.
How often should TPMS sensors be replaced?
TPMS sensors typically last anywhere from 5-10 years. However, if you live in an area with harsh weather conditions or frequently drive on rough terrain, your sensors may need to be replaced more frequently. It’s a good idea to have your TPMS sensors checked by a mechanic during regular maintenance visits.
Conclusion
Installing a TPMS sensor on your Subaru is a simple process that can be done at home with the right tools and knowledge. By following the steps outlined in this guide, you can replace your faulty TPMS sensors and ensure accurate monitoring of your tire pressure.
