P2144 code means the powertrain control module has detected a fault with the rate of flow through the exhaust gas recirculation vent control circuit.
How to Replace an Exhaust Gas Recirculation (EGR) Valve
The exhaust gas recirculation (EGR) valve can cause drivability problems if it fails and should be replaced to avoid engine performance issues.
How to Replace an Exhaust Gas Recirculation (EGR) Pressure Feedback Sensor
Exhaust gas recirculation (EGR) systems use a pressure feedback sensor to tell the powertrain control module (PCM) how much exhaust gas is flowing.
How to Replace an Exhaust Gas Recirculation (EGR) Control Solenoid
Exhaust gas recirculation (EGR) systems are controlled by the EGR control solenoid, which is controlled by the powertrain control module (PCM).
How to Replace an Exhaust Gas Recirculation (EGR) Temperature Sensor
Exhaust gas recirculation (EGR) temperature sensors monitor the EGR cooler's operation. One is on the exhaust manifold and one is near the EGR valve.
How to Replace an Exhaust Gas Recirculation (EGR) Cooler
Exhaust gas recirculation (EGR) coolers lower the temperature of the exhaust gas before it enters the car engine. EGR coolers are mainly for diesel.

How to Replace an EVP Shut Off Solenoid
An EGR valve is essential to the EGR system in your vehicle. For this valve to work, the EVP shut off solenoid must monitor its position and function.
How to Replace an Exhaust Gas Recirculation (EGR) Vacuum Modulator
The EGR vacuum modulator meters the EGR valve in some car systems. Some signs of a failing EGR vacuum modulator include stalling and a rough idle.
Symptoms of a Bad or Failing EGR Vacuum Modulator
Common signs include engine performance issues, the Check Engine Light coming on, and failing an emissions test.
Symptoms of a Bad or Failing EGR Cooler
Common signs include engine overheating, exhaust leaking, and the Check Engine Light coming on.

How to Buy a Good Quality Exhaust Gas Recirculation (EGR) Tube
Exhaust Exhaust gas recirculation tubes (EGR tubes) are responsible for moving a very small amount of gas from the exhaust manifold to the intake manifold in order to help reduce emissions of nitrous oxide. This tube is the key point...
How Long Does an EGR Cooler Last?
Within Within your vehicle is a part called the EGR cooler. EGR stands for Exhaust Gas Recirculation. This cooler is responsible for taking care of the exhaust gases once they leave the engine. It cools these gases so they are...
How Long Does an EVP Position Sensor Last?
An An integral part of your vehicle's EGR (exhaust gas recirculation) system is the EVP position sensor. This sensor has the important job of figuring out where the gate is positioned in order to allow gases to pass through to...
How to Buy a Good Quality Exhaust Gas Recirculation (EGR) Valve
The The exhaust gas recirculation valve (EGR valve) serves to dramatically reduce the emissions that are key contributors to pollution in the air. While EGR systems were not routinely added to engines until 1973, nearly all engines produced or on...
How Long Does an Exhaust Pressure Control Valve Last?
The The exhaust pressure control valve is used in diesel vehicles as part of its EGR (exhaust gas recirculation) system. The EGR system is meant to bring down the amount of emissions that vehicles produce, as the gas that is...
How to Clean an EGR Valve
The The EGR valve is the heart of the emissions system on an engine. EGR is an acronym for Exhaust Gas Recirculation, and that is exactly what it does. This wonderful environmentally-friendly device opens up during certain engine conditions and...
