Test DF: Step 10

10) Code 72: Repeat Dynamic Response (Goose) Test  Code 72 indicates that MAP sensor output did not change enough during dynamic response (Goose) test. Possible causes for this code are:

• System failed to detect partial Wide Open Throttle (WOT)
• Incorrect MAP sensor vacuum line routing
• Faulty MAP sensor

Repeat KOER Self-Test. Ensure complete WOT is performed during Dynamic Response portion of test. If KOER Code 72 is still present, go to next step. If not, service other codes as necessary.
