you can also verify the speed sensor is not an issue by performing the ecu diag check for a code 14 ( the how to perform ecu test is in tech section faq) I doubt it is a problem from what your telling us. Your hicas will still work as long as the speed sensor isnt bad. I assume you do not have a hicas warning light coming on. Hope this helps
