P2144 OBD-II Trouble Code: Exhaust Gas Recirculation Vent Control Circuit Low

Check Engine Light

** Diagnostic Trouble Code (DTC): P2144**

P2144 code definition

Exhaust gas recirculation vent control circuit low.

What the P2144 code means

This trouble code indicates that the powertrain control module has detected a malfunction with the rate of flow through the exhaust gas recirculation vent control circuit.

What are the causes of the P2144 code?

Some of the potential causes of this trouble code may include:

  • Restricted exhaust gas recirculation plumbing may cause this issue.
  • The vent control solenoid could be faulty.
  • The exhaust gas recirculation valve could be malfunctioning.
  • A vacuum leak may exist.
  • Damaged wiring or connectors that are associated with this system could be damaged.
  • The powertrain control module could be malfunctioning.

What are the symptoms of the P2144 code?

Symptoms of this trouble code that the driver may experience are generally limited to a Check Engine Light.

How does a mechanic diagnose the P2144 code?

A mechanic may begin diagnosing this trouble code by checking around the exhaust gas recirculation valve for any damaged wiring or connectors that may be present. Then the mechanic would inspect all the vacuum lines and possibly run a vacuum test to see if any vacuum leaks exist. After that, the mechanic would then test the exhaust gas recirculation valve and the vent control solenoid using the manufacturer's recommended procedure. The mechanic may also remove the exhaust gas recirculation valve to inspect the inside of the plumbing for restrictions of carbon deposits.

If the problem has not been determined after these steps have been taken, the problem may lie in the powertrain control module. After all parts of this system have been checked over by the mechanic, the mechanic would then relay his/her findings over to you to make an informed repair decision.

Common mistakes when diagnosing the P2144 code

A common mistake that could be made when diagnosing this trouble code would be to replace the exhaust gas recirculation valve without properly testing the system. Many times the plumbing for the exhaust gas recirculation valve will become restricted preventing the functionality of the vent control solenoid.

How serious is the P2144 code?

This code would not rank high on the seriousness scale. This is because it will not cause any driveability issues or safety issues. The only symptom that the driver is likely to experience would be the Check Engine Light.

What repairs can fix the P2144 code?

Repairs that could potentially fix this trouble code would include:
