What P2144 means
P2144 reports a low signal in the circuit that drives the EGR vent solenoid – the valve that bleeds vacuum from a vacuum-operated EGR valve so it can close. With the usual low-side switching, a control wire touching ground keeps the solenoid energised regardless of the command. Whether that leaves the EGR valve unable to open or unable to close depends on the plumbing, but in both cases the EGR rate can no longer be controlled. Ford's 2014 spark-ignition code list includes P2144 with the warning lamp and a continuous test, though Ford gives no threshold; no other public manufacturer document names the code. P2143 covers an open circuit and P2145 the high fault of the same solenoid. Typical results are rough running, higher NOx or a failed EGR readiness test.
P2144 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 P2144
- Check engine lamp on
- Rough idle or hesitation
- Emissions test failure because of EGR
Common causes of P2144
- Most likelyControl wire chafed through and shorted to ground
- PossibleInternal short in the vent solenoid coil
- PossibleCorrosion bridging terminals in the connector
- 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 P2144 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. |
| 44 | The exact fault in that area. |
What to do next
- Note P2144 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 P2144
What does P2144 mean?
P2144 means "EGR Vent Control Circuit Low". P2144 reports a low signal in the circuit that drives the EGR vent solenoid – the valve that bleeds vacuum from a vacuum-operated EGR valve so it can close. It is a generic code, so it means the same on every make.
Is it safe to drive with P2144?
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 P2144 fail an emissions test?
Yes, it can. P2144 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 P2144 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 P2144 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
