P1494 = Evap Leak Detection Pump Pressure Switch Condition
 

The Engine Control Module (ECM) has detected that leak detection pump switch change after solenoid was energized.

Possible causes:

  • Faulty Leak detection pump defective
  • Leak detection pump defective circuit open or shorted
  • Faulty Solenoid

Start by clearing the code, if the codes comes back you may have to replaced the Leak detection pump.
