What Causes Insufficient Purge Pump Speed?
1 Answers
Electrical Circuit Fault: Check the purge pump's wiring connections and plugs for any loose connections to confirm this issue. If there's a fault in the purge pump's wiring, it can lead to insufficient power supply to the pump, resulting in reduced pump speed. Air Leak in the Hose: Inspect the hose connections between the purge pump and the charcoal canister for looseness and check the hose surface for any damage. If found, it can cause air leaks in the hose, leading to insufficient purge pump speed. Purge Pump Failure: Use a vehicle diagnostic tool to read the purge pump's data stream and analyze whether its operating condition is normal. If there are no air leaks in the hose and the wiring connections are secure, the purge pump itself may be faulty.
