Sensor faults and backup sensors

In Simple Terms

If a car's sensors break down during a race, teams are allowed to switch to backup sensors and adjust settings to compensate. However, these backup sensors cannot make the car perform better than it originally would have—they're just a safety measure to keep the car running, not an upgrade.

• Teams may use backup sensors if primary sensors fail or malfunction
• Manual or automatic setting adjustments are permitted when switching sensors
• Backup sensors must not provide any performance enhancement to the car
• This rule ensures fair competition while allowing reliability contingencies
