Tyre Deflation Warning problem

I have had my Honda Civic for four years, from new. It has done 26,000 miles. In that time the tyre deflation warning light has come on about a dozen times - and there was never anything wrong with the pressures. The Honda dealer is mystified. Any thoughts?

These systems are activated if there is a disparity in temperature that can occur when tyres heat up on a journey and their pressures increase. It's possible that filling the tyres with nitrogen rather than air (80% nitrogen) will stabilise the tyre temperatures and pressures and cure this.
