Assistance for Singapore Cars with Malfunctioning “Tyre Pressure Monitoring System (TPMS)” Sensors MyMechanic

What TPMS faults look like

• Solid or flashing TPMS light with “Sensor Fault” or “System Error” messages.
• Sudden zero or dashes for one wheel’s pressure while others read normally.
• Readings don’t move despite temperature or speed changes.
• Warning after tyre rotation, wheel swap, or recent puncture repair.

Immediate steps on the roadside

• Prioritize safety: Pull well off live lanes with hazards on; avoid stopping on blind bends or narrow shoulders.
• Visual check first: If a tyre looks low, avoid long drives—gentle relocation is fine if the sidewall isn’t collapsing.
• Touch test with care: Warm tyres are normal after driving; if one rim feels hot versus others, stop and request assistance.
• Don’t chase numbers: A faulty sensor can mislead; trust the visual check and tyre posture more than a single suspect reading.

How MyMechanic helps on the spot

• Tyre triage: Inspect for nails, cuts, bead leaks, and valve issues; support with safe inflation and pressure equalization where appropriate.
• Puncture decisions: If damage is in a repairable area and conditions are safe, stabilize for a short relocation; otherwise, coordinate a controlled recovery.
• Sensor sanity: Identify likely dead sensor batteries, mismatched sensor IDs after rotations, or missing TPMS caps/cores; advise next‑step options.
• Controlled towing: Low‑angle flatbed loading to protect low‑profile tyres and rims; no strapping over sensors or valve stems.
• Clear communication: ETAs, route options, and plain‑English guidance to keep choices calm and practical.

Common causes of TPMS issues

• Sensor battery end‑of‑life causing intermittent dropouts.
• Relearn needed after rotations or new sensors—IDs must be mapped.
• Valve and stem problems: corrosion or damage leading to slow leaks and bad readings.
• Temperature swings: morning cold drops pressure and triggers alerts; leaks remain leaks.

Smart prevention before a long drive

• Baseline pressures cold at manufacturer spec; don’t forget the spare.
• Rotation with relearn so the car knows which sensor is where.
• Protect stems: non‑metal caps that won’t seize; refresh service kits when changing tyres.
• Monitor patterns: recurring slow drops on one corner suggest bead or stem issues to fix before travel.

• Cross‑border know‑how across Malaysian expressways, city streets, and rural stretches.
• Safety‑first approach: stabilize tyres and relocate when sensible; recover the car when a rim or sidewall is at risk.
• 24/7 support: nights, weekends, basements, toll plazas, and rain covered with steady communication.
• Clear, calm updates: ETAs, route planning, and simple next steps—no jargon, just practical guidance.

Frequently Asked Questions

Conclusion

TPMS faults need calm checks, not guesswork. With safe inflation, sensible puncture decisions, and relearn guidance—or controlled flatbed recovery when risk rises—journeys stay safe and tyres stay protected.
