What Causes the Purge Pump to Fail?
1 Answers
Here are the reasons why the purge pump may fail: The motor inside may malfunction, requiring professional repair, and a missing phase in the three-phase power supply can also cause burnout. Below are the effects of a failed purge pump: 1. Reduced Vehicle Power: A damaged purge pump prevents fuel vapor from the charcoal canister from entering the cylinders, leading to a lower concentration of combustible air-fuel mixture in the engine, which reduces the vehicle's power output. 2. Increased Fuel Consumption: If the charcoal canister becomes saturated with fuel vapor but the purge pump fails to expel it, subsequent fuel vapor cannot be recycled, naturally leading to higher fuel consumption.
