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.

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.
