Code P144E Dodge Description
The P144E diagnostic trouble code for Dodge vehicles indicates a problem with the EGR (Exhaust Gas Recirculation) Cooler Bypass Status Line Circuit being detected as low. The EGR system is responsible for redirecting a portion of the exhaust gases back into the intake manifold to reduce emissions and control combustion temperatures. The EGR Cooler Bypass is a component that helps regulate the temperature of the exhaust gases before they are recirculated.
Common Causes of P144E Dodge
- Faulty EGR Cooler Bypass valve
- Wiring issues or damaged connectors in the circuit
- Malfunctioning EGR Cooler Bypass sensor
- Carbon buildup in the EGR system
- ECM (Engine Control Module) software or hardware issues
Symptoms of P144E Dodge
- Reduced engine power
- Rough idling or stalling
- Decreased fuel efficiency
- Check engine light illuminated
- Increased emissions output
How to Fix P144E Dodge
- Use a diagnostic scanner to retrieve the trouble code and determine the specific cause of the issue.
- Inspect the EGR Cooler Bypass valve, sensor, and wiring for any visible damage or corrosion.
- Test the EGR Cooler Bypass valve and sensor for proper operation using a multimeter.
- Clean out any carbon buildup in the EGR system components.
- Replace any faulty EGR system components as needed.
Cost to Fix P144E Dodge
The cost of repairing a P144E code for the EGR Cooler Bypass Status Line Circuit low can vary depending on the specific cause of the issue and the labor rates at the auto repair shop.
