Can you drive with TPMS error?
You can typically continue driving for a short distance when a TPMS warning appears, but you should treat it as a red flag and address it promptly. Check tire pressures and arrange service to diagnose whether the issue is a low tire or a malfunctioning TPMS system.
Understanding what TPMS warnings mean
There are two common TPMS warning scenarios you may encounter, and they require different checks to stay safe on the road.
- Low tire pressure warning: A sensor reads that one or more tires are underinflated. This can happen from natural air loss, temperature changes, or a puncture.
- TPMS malfunction or system fault: The TPMS cannot communicate with the tires or the control module, so there is no reliable pressure data from the system.
- Indirect TPMS indicators: Some systems infer underinflation from wheel speed sensors or rolling diameter differences, which can mislead if tires wear unevenly or sensors are off.
In any case, the prudent step is to verify the actual tire pressures with a gauge and inspect the tires for damage, punctures, or excessive wear. When in doubt, treat the warning as a signal to check the tires and seek service.
What to do if a TPMS warning lights up
To stay safe and minimize risk, follow these practical steps. This list helps you respond effectively to both low-tire and TPMS malfunction alerts.
- Safely pull over as soon as practical and assess the situation, especially if you notice vibrations, a hissing sound, or obvious tire damage.
- Check the tire pressures with a reliable gauge. Compare readings to the vehicle’s recommended inflation pressure found on the door jamb placard or in the owner's manual.
- Inflate any underinflated tire(s) to the recommended pressure, using cold tires for the most accurate reading.
- Recheck all tires after a little driving to confirm the pressures have stabilized. If a tire repeatedly goes low, inspect for punctures, leaks, or valve stem issues.
- If the warning light remains on after proper inflation, or if the system displays a fault indication rather than a low-pressure warning, the TPMS itself likely has a fault and needs professional diagnosis.
- Have a qualified technician inspect and service the TPMS sensors, wiring, and control module. Replacing defective sensors or batteries, or reprogramming the system, may be required.
Even if you manage to inflate tires to the correct pressures, continue to monitor tire performance and plan a visit to a tire shop or dealership to ensure the TPMS is functioning correctly and safely.
Safety, legal considerations, and practical tips
Driving with a TPMS warning is common, but it carries safety and regulatory considerations that vary by location and vehicle. Keep these points in mind:
- Underinflated tires are at higher risk for blowouts, poor handling, increased wear, and reduced fuel efficiency. Regularly check tire pressures when the tires are cold.
- Run-flat tires may allow limited driving after a puncture, but TPMS should still be used to manage safety, and repair is typically needed after the temporary drive.
- Some regions require TPMS to be functional for vehicle inspections or registrations; check local laws and inspection rules where you live.
- Carry a portable tire inflator and a reliable gauge in your vehicle as a precaution in case you need to adjust pressures between services.
In all cases, treating a TPMS warning as a call to action—checking pressures, inspecting tires, and scheduling service—helps reduce risk on the road and protects tire integrity over time.
Summary
A TPMS warning indicates potential underinflation or a fault in the monitoring system. You can usually drive for a short distance if you address the tire pressures and seek service promptly to diagnose and repair the TPMS. Prioritize safety by verifying tire pressures, inspecting tires for damage, and having the system checked by a qualified technician. Regulations vary by location, so be aware of local inspection or safety rules and keep emergency supplies on hand for peace of mind on the road.
