article.
- Reconnect LDP pressure hose to LDP. Allow Miller Tool Kit (6872) to build pressure to at least 14 in. of water vacuum. Using scan tool, stop all actuations. Observe pressure on Miller Tool Kit (6872). If pressure dropped when actuation was stopped, go to next step. If pressure did not drop when actuation was stopped, replace LDP and filter. Perform TEST VER-5A.
- Disconnect Miller Tool Kit (6872) from EVAP system. Disconnect EVAP purge hose from EVAP duty cycle solenoid. EVAP duty cycle solenoid is located near left strut tower. Start engine and let it idle. Go to next step.
- Wait 3 minutes or until EVAP duty cycle solenoid starts to operate. If vacuum is pulsating at EVAP canister side of EVAP duty cycle solenoid, no problem present at this time. Perform TEST VER-5A. If vacuum is not pulsating at EVAP canister side of EVAP duty cycle solenoid, go to next step.
- Disconnect vacuum hose at throttle side of EVAP duty cycle solenoid. If engine vacuum is present, replace EVAP duty cycle solenoid. Perform TEST VER-5A. If engine vacuum is not present, repair obstruction in vacuum hose or throttle. Perform TEST VER-5A.
