fords use this. maybe others but only Ford calls it a dpfe. [differential pressure feedback e.g.r] they were notorious failures in the 90's . what the do is bypass a little exhaust through an oriface tube on either side of the catalytic converter. the dpfe measures the pressure difference to determine if the cat is plugged [ or not doing its job] if it measures values out of range it will set a trouble code.
