Some customers may comment on a ticking or clicking noise heard inside the vehicle on the passenger side. The noise may be noticeable with the engine on and at idle, with the vehicle in PARK, and with the HVAC and radio off.
The noise may be caused by normal EVAP purge valve operation. The EVAP purge valve operation may be internally grounding out, creating a noise path through the coolant inlet and outlet hoses/pipes
Perform the diagnosis FIRST to determine if the EVAP purge valve operation is normal. Confirm the customer concern by using a Tech 2® to disable the EVAP purge valve. If the ticking or clicking noise heard inside the passenger side of the vehicle is gone, perform the following steps:
