what means code 1494for dodge dakota 03

mariobarrera, I believe you are asking about the P1494 error code. P1494 Dodge - EVAP Leak Detection Pump Pressure Switch Condition. Possible causes

  • Faulty Leak Detection Pump (LDP)
  • Leak Detection Pump (LDP) harness is open or shorted
  • Leak Detection Pump (LDP) poor electrical connection Possible causes
  • Faulty Leak Detection Pump (LDP)
  • Leak Detection Pump (LDP) harness is open or shorted
  • Leak Detection Pump (LDP) poor electrical connection From here. That code means the power circuit to the pump (or the pump itself) is bad. It might be a short or the pump could have died. Also, check all your Vacuum lines, a leaky line might cause that as well. Take a look at this video as well. Hope this helps, good luck.
