Para-toluenesulfonic acid is too strong an acid to have its pKa determined directly in an aqueous solution. Jerry March in "Advanced Organic Chemistry" (4th edition, p. 250) gives a general value of -(minus!) 6.5 for aromatic sulfonic acids, ArSO3H. His reference for that is Cerfontain & al., Tetrahedron Letters 1975, p. 3639. I hope this helps.
