If the tyre-pressure warning has come on in your Porsche Taycan (2020–present) after you’ve adjusted the pressures or changed a wheel, you handle it through the central display (PCM). The Taycan uses sensors in the wheels and runs staggered tyres (wider rears). The light on its own is the monitoring symbol, not a fault — it’s asking you to check the pressures and, if you’ve changed wheels, confirm the fitted profile.
How the System Works on the Taycan
The Taycan runs a direct system: each wheel has its own sensor transmitting the actual pressure, so the PCM can show a live value per corner. Because the car wears staggered tyres, the front and rear target pressures differ — and the system needs to know which wheel/tyre profile is fitted (for example a seasonal or size change) so it applies the right thresholds. For a simple top-up there’s nothing to reset; after a wheel change you confirm the profile so the sensors are judged against the correct figures.
After Adjusting Pressures
For a simple top-up, no manual reset is needed — just drive the car and the system re-reads the corrected pressures.
Getting Ready
- Set the tyres cold — before driving, or after the car has stood a few hours.
- Use the correct figures for the fronts and rears separately; they differ on the staggered fitment, and the label lists them by axle.
- Note whether you’re on summer or winter wheels, or a different size, so you can pick the matching profile in the PCM.
- Have the car switched on with the PCM active so you can reach the tyre-pressure page.
After Changing Wheels or Tyres
- Set the tyres to the correct cold pressures (fronts and rears differ).
- On the PCM / multifunction display, open the tyre-pressure page.
- Select the correct wheel/tyre setting (e.g. summer/winter or the size fitted).
- Drive the vehicle to complete the procedure.
If the Warning Stays On
- Recheck every tyre against the correct front/rear figures — one below spec keeps the warning on.
- Pick the matching wheel/tyre profile after a seasonal swap, or the thresholds won’t line up with the fitted tyres.
- Drive a few minutes so the sensors report; it won’t always clear the instant you set the pressures.
- On a cold morning pressures read low — set them to the label figure when cold rather than chasing a warm gauge.
- If one corner keeps falling after you’ve set it, suspect a slow puncture or a leaking valve.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
What Happens Next
Once the pressures are right and, where needed, the correct profile is selected, the warning clears after a short drive and stays off for the trip. Because it’s a direct system, the PCM should also show sensible live values at each corner once the sensors have reported. If the light returns on a cold start, that’s normal temperature-related loss — top up to the label figures and it settles.
Frequently Asked Questions
How do I reset the tyre pressure warning on a Porsche Taycan?
After a top-up just drive — the system re-reads the corrected pressures on its own. After a wheel or tyre change, set the correct cold pressures, select the matching wheel/tyre profile on the PCM tyre-pressure page, and drive to confirm. Remember the fronts and rears take different pressures on the staggered fitment.
Does the Taycan have sensors in the wheels?
Yes — it’s a direct system, so each wheel has its own sensor reporting the actual pressure. That’s why the PCM can show a value per corner, and also why a sensor with a flat battery can keep the warning on even when every tyre is correctly inflated.
Why won’t it clear?
Usually a tyre still below spec, or the wrong wheel/tyre profile selected after a wheel change. Check all four against the correct front and rear figures, confirm the fitted profile in the PCM, then drive a few minutes so the sensors can report before the warning drops.
Do I need a tool?
No for a normal reset; the whole thing is done from the PCM plus a short drive. A tool is only needed if a sensor is replaced, so the new sensor’s ID can be registered to the car. If a fresh sensor was fitted and the car won’t recognise it, that registration is a workshop job.
Why are the front and rear pressures different?
The Taycan runs staggered tyres — wider rears than fronts — so each axle has its own target pressure. Always read the door-pillar label by axle and set the fronts and rears to their own figures. Using the front figure all round, or vice versa, can leave a corner reading out of range and keep the warning on.
Do I need to reset after switching to winter wheels?
Set the correct cold pressures for the winter fitment, then confirm the matching wheel/tyre profile on the PCM tyre-pressure page so the system judges the sensors against the right thresholds. Drive a few minutes to let the sensors report. If the winter set has its own sensors, they may need registering before the car reads them.
If the warning came on with other lights, decode the code on autodtcs.com.
