What P2145 means
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.
P2145 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2145
- Check engine lamp on
- EGR inactive, sometimes pinging under load on gasoline engines
- EGR readiness not completed
Common causes of P2145
- Most likelyControl wire shorted to battery voltage
- PossibleShorted vent solenoid coil drawing excess current
- Less likelyFaulty output stage in the engine control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2145 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 45 | The exact fault in that area. |
What to do next
- Note P2145 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2145
What does P2145 mean?
P2145 means "EGR Vent Control Circuit High". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2145?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2145 fail an emissions test?
Yes, it can. P2145 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2145 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2145 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
