Usually not. In most cases you can replace only the faulty TPMS sensor rather than all four. There are good reasons to replace just one or two, and situations where replacing the entire set makes more sense.
Understanding TPMS: direct versus indirect systems
Tire Pressure Monitoring Systems (TPMS) come in two main flavors. Direct TPMS uses a sensor mounted in each wheel that measures air pressure and transmits the data to the car’s computer. These sensors are battery-powered and designed to last several years. Indirect TPMS doesn’t use a physical sensor in each wheel; instead it infers low pressure from wheel speed and other signals via the anti-lock braking system (ABS) sensors. Indirect systems don’t require wheel-mounted batteries, but they still require calibration or relearning when tires are changed or pressures are adjusted.
When you should consider replacing a single sensor (not all four)
Here are common circumstances in which replacing only the faulty unit is appropriate. This list explains why you might not need to replace all four sensors at once.
- The sensor in one wheel has failed or its battery has died, causing an inaccurate or absent TPMS alert.
- You’ve serviced or remounted a tire on a specific wheel and the sensor was damaged or cannot be reused.
- The other three sensors are newer or still well within their expected battery life.
- Your vehicle requires a TPMS relearn after installing a new sensor, but the fix is isolated to the wheel with the issue.
When one sensor fails, replacing just that sensor is the standard approach for most vehicles. If the vehicle uses direct TPMS, the failed sensor is typically replaced as a unit, and the system is relearned to recognize the new sensor. If your car uses indirect TPMS, there may be no sensor to replace in the wheel, and the recalibration procedure focuses on the system’s software interpretation rather than hardware replacement.
When you might replace all four TPMS sensors
There are situations in which replacing all four sensors at the same time is reasonable or advantageous. This list outlines common scenarios where a full set replacement makes sense.
- All four sensors are approaching the end of their typical battery life (commonly 5–10 years depending on usage and sensor type).
- You’re replacing tires on all four wheels and want uniform sensor age and performance to minimize future trouble calls or relearns.
- You’re installing aftermarket sensors that you expect to have a longer service life or better compatibility with your vehicle’s TPMS control module.
- Your shop recommends replacing the entire set to avoid multiple service visits, especially if several sensors show marginal readings or historical faults.
Replacing all four sensors is a common choice when you’re performing a full tire rotation or replacement on all corners, or when the tires are relatively new but the sensors themselves are old and nearing end of life. It can also reduce the likelihood of repeated TPMS faults spanning multiple wheels.
Practical steps and considerations you should know
Before and after deciding which route to take, there are practical steps to ensure the TPMS remains accurate and reliable.
- Relearn or programming: After installing new sensors, most vehicles require a TPMS relearn procedure. This can usually be done with a scan tool at a shop or, in some cases, by following a specific driving procedure described in the owner’s manual.
- Calibration versus replacement: Direct TPMS requires sensor replacement for a failed unit; indirect TPMS relies on software calibration rather than wheel-mounted devices.
- Wheel and tire integrity: If a tire is replaced due to a puncture or damage, inspect the wheel and valve stem; sometimes the stem or valve core replacement is needed along with the sensor.
- Vehicle-specific nuances: Some cars have more strict relearn requirements or OEM-specified sensor types. Verify compatibility and whether your vehicle’s system prefers OEM sensors or aftermarket equivalents.
Understanding these steps helps you anticipate costs and installation timelines, and it clarifies why a shop might advocate replacing all four in some cases rather than chasing intermittent faults on a single wheel.
Costs, warranties, and what to expect
Cost ranges vary by vehicle, sensor type, and regional labor rates. Here is what buyers typically encounter. Note that these figures are approximate and can vary widely by market and vehicle model.
- Direct TPMS sensor price: roughly $40–$100 per sensor for aftermarket parts, higher for OEM sensors.
- Labor and mounting: often $40–$100 per wheel, depending on the shop and whether you’re already having tires replaced.
- Relearn/diagnostic fee: some shops charge a separate fee for the TPMS relearn procedure.
- Warranty: many direct TPMS sensors come with a 1–2 year warranty, sometimes longer if purchased as part of a tire package.
Expect total costs to range from a single-sensor replacement (roughly $100–$250, depending on tires and vehicle) to a full four-sensor replacement (roughly $300–$900, including parts and labor) if you opt for four new sensors and a full relearn.
Bottom line
In most cases you do not have to replace all four TPMS sensors if only one is failing. Direct TPMS systems allow you to replace the faulty sensor and perform a relearn, while indirect TPMS relies more on software calibration. You would replace all four sensors mainly when they are all near the end of their life, when you’re installing tires on all four corners, or if you want the assurance of uniform sensor performance across the vehicle. Always verify your vehicle’s TPMS type, follow the relearn procedure, and consult with a qualified technician to determine the most cost-effective and reliable approach for your situation.
Summary
Bottom line: you usually don’t need to replace all four TPMS sensors at once. Replace the faulty unit if it’s failing, especially with direct TPMS. Consider replacing all four when sensors are old, tires are being replaced on all wheels, or uniform sensor performance is desired. Indirect TPMS changes the approach somewhat, focusing on software calibration rather than wheel-mounted hardware. Plan for a relearn after any replacement and confirm compatibility with your vehicle’s system to ensure accurate tire pressure monitoring.

Do Subaru TPMS sensors need to be programmed?
Subaru TPMS Replacement
If a sensor proves faulty or is damaged then it will need to be replaced. This requires a new sensor to be fitted and the ECU to be reprogrammed with its unique ID and its position on the vehicle.

Should all 4 TPMS sensors be replaced at the same time?
And tires. So replace all four and avoid three comebacks i'm Andrew Markell thank you very much.
Can I replace only one TPMS sensor?
If one of your TPMS sensors fails and needs replacement, you can replace it individually.
