The humidity sensor plays a role in adjusting air intake systems and controlling emissions on DAF trucks. However, under certain operating conditions, or after modifications to the intake or emissions systems, the humidity sensor can trigger errors, activate emergency modes, or reduce engine performance.
Using TruckTools software, we can completely disable the humidity sensor function within the ECU software, eliminating related errors and limitations without physically removing or replacing the hardware.

This service is available remotely — our specialists will connect to your truck over the internet, diagnose the system, and apply the necessary changes. Alternatively, you can purchase a TruckTools license and independently manage such adjustments for your fleet, offering full flexibility in truck customization.

Disabling the humidity sensor is especially relevant for vehicles operating in dusty environments, under fluctuating humidity levels, or when installing alternative intake systems. It helps avoid false error codes, maintain system stability, and improve overall vehicle reliability.
