Well... Definitely there is something wrong with the unit. It would be difficult to know what the exact problem is without first hand experience. The simplest way to find out is plug a DST 2 analyzer and let the machine do the talking. All Toyota branch has one so does Denso. If it doesn't show up on the analyzer, then the problem would be mechanical. If you have more questions, you can text me at 0932-3287778
