P2145EGR Vent Control Circuit High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
P2145 is the high fault in the vent solenoid circuit of the EGR system: the control line shows supply voltage while the module tries to pull it to ground, or the driver detects overcurrent through a shorted coil. The output then cannot switch the solenoid on, so the vent stays in its rest state – depending on design the EGR valve either cannot be released quickly or cannot be held, and the module normally stops using EGR. Ford's 2014 spark-ignition code list names P2145 alongside P2144, both with the warning lamp and a continuous test; thresholds are not given and no further manufacturer document is public. For the vent concept itself see Ford's separate vent and control outputs and Kia's duty-mapped vent solenoid. Open circuit is P2143, low fault P2144.
What you may notice
  • Check engine lamp on
  • EGR inactive, sometimes pinging under load on petrol engines
  • EGR readiness not completed
Likely causes
  • LikelyControl wire shorted to battery voltage
  • PossibleShorted vent solenoid coil drawing excess current
  • RareFaulty output stage in the engine control module
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
Repair
Easy · Often possible to do yourself.Typical cost: €30 – €250
