This summary uses the existing diagnostic information shown in full below.
The car's computer is saying there's a problem with the part that helps control the air going back into the engine. It's like if a fan in your room wasn't working right.
This code indicates that the EGR (Exhaust Gas Recirculation) vent control circuit is experiencing a low voltage condition.
The P2144 code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the EGR vent control circuit. The EGR system helps reduce emissions by recirculating a portion of the exhaust gases back into the engine cylinders. The vent control circuit is responsible for regulating the flow of these gases.
• Check Engine Light is on
• Poor engine performance
• Increased emissions
• Faulty EGR vent control solenoid
• Wiring issues or poor electrical connections
• Failed ECM
EGR: Exhaust Gas Recirculation
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the EGR vent control solenoid and its wiring.
• Test the voltage and continuity of the circuit.
• Replace the EGR vent control solenoid if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance checks
• Ensure proper electrical connections
• Use quality fuel to prevent carbon build-up
Sensor Issue
• Have a professional mechanic inspect the vehicle.
• Avoid driving long distances until the issue is fixed.
Check with the vehicle manufacturer for specific warranty coverage on emissions-related components.
The P2144 code has been associated with EGR system issues in various vehicle models over the years, often linked to solenoid failures.
Moderate – While the vehicle may still be drivable, it can lead to increased emissions and potential engine performance issues.
Driving with a malfunctioning EGR system may lead to higher emissions, which can be against environmental regulations.
• Engine at operating temperature
• Vehicle in park or neutral
The EGR vent control solenoid is typically located near the engine, often mounted on or near the intake manifold.
Q: Can I drive with a P2144 code?
A: It's possible to drive, but it's not recommended as it can lead to increased emissions and engine performance issues.
Q: How do I reset the Check Engine Light after fixing the P2144 code?
A: You can use an OBD-II scanner to clear the code, or the light may turn off automatically after a few driving cycles if the issue is resolved.
