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.
