Mini Cooper

I have the following codes, P-2418 evap emissions open, P-2400 Evap Leak detected, P-2419 Evap emission switch, P-2401 Evap emissions circuit low. I have replaced the gas cap and the fuel leak detection pump already but the check engine light come back on after the a few minutes and not all of the codes clear. Do I have a wiring issue or something else going on? I am at a loss. Thank you Jim


First off it would be great to know which codes are still there. The good news is as long as the check engine light is NOT flashing, it is safe to drive. We can look for the correlation between all the codes and test accordingly.

Mini Code P2148

Description: Evaporative Emission System Switching Valve Control Circuit /Open

Code p2418 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. EVAP system – Check fuel cap, canister, valves or components

Mini Code P2400

Description: Evaporative Emission System Leak Detection Pump Control Circuit/Open

Code p2400 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. Open fuse
  7. EVAP system – Check fuel cap, canister, valves or components

Mini Code P2401

Description: Evaporative Emission System Leak Detection Pump Control Circuit Low

Code p2401 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. Battery voltage low
  7. EVAP system – Check fuel cap, canister, valves or components
