Summary

Part Description: Short Runner Valve (Actuator) Issue Description: Issue 1~ JC,JS '08-09MY 3.5L only~ Caution - Do not replace the intake manifold for a short runner valve (SRV) fault (P1004 / P2008 / P2016 / P2017) or for a manifold tuning valve (MTV) fault (P1005 / P2077 / P2078). Instead follow the service procedure to investigate P codes associated with diagnosis of the SRV or MTV, then cycle the actuator using a diagnostic tool and verify that the PWM output is 50 (+ 2%) de-energized and 80 (+ 2 %) energized. If no problems observed, then idle the vehicle and verify the correct PWM output (50 + 2% PWM). Replace the actuator if you do not get the desired output. Issue 2~ If the SRV actuator or intake manifold is being replaced for a P1004 Short Runner Valve Performance fault code and the vehicle was built prior to 2/5/07 , technicians must complete the module reflash and verification test per TSB 18-003-07 REV. A to ensure the parts need to be replaced. Please reference TSB 18-003-07 REV. A for specific details on the procedure.
