Dynamic Response Check

DYNAMIC RESPONSE CHECK
The dynamic response check is used on some applications to verify operation of the TP and MAF sensors during the brief Wide-Open Throttle (WOT) performed during the Engine Running Self-Test. The signal for the operator to perform the brief WOT is a single pulse or 10 code on the STAR Tester.
