This summary uses the existing diagnostic information shown in full below.
This code means that a part of the car that helps clean the air going into the engine isn't working well enough.
The EGR (Exhaust Gas Recirculation) cooler is not cooling the exhaust gases sufficiently before they are recirculated back into the engine.
The P14D0 code indicates that the low pressure EGR cooler is not effectively cooling the exhaust gases as expected. This could be due to a malfunction in the cooler itself, a blockage, or an issue with the sensors monitoring the system. The EGR system reduces nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the engine cylinders, and the cooler reduces the temperature of these gases to improve efficiency and reduce engine knock.
• Check Engine Light is on
• Reduced engine performance
• Increased emissions
• Faulty EGR cooler
• Blocked EGR passages
• Defective EGR temperature sensor
EGR: Exhaust Gas Recirculation
Cooler: A device that reduces the temperature of a fluid or gas
• Use an OBD-II scanner to confirm the code.
• Inspect the EGR cooler for blockages or damage.
• Test the EGR temperature sensor for proper operation.
• Replace the EGR cooler if faulty.
• Clean any blockages in the EGR passages.
• Replace the EGR temperature sensor if defective.
• OBD-II scanner
• Wrench set
• Multimeter

Moderate
• Ford F-150
• Chevrolet Silverado
• Ram 1500
• Regular maintenance of the EGR system.
• Use high-quality fuel to reduce deposits.
• Ensure timely replacement of air filters.
Engine Performance
• Do not ignore the Check Engine Light.
• Visit a mechanic if you notice reduced performance.
• Regularly check and maintain the EGR system.
Check with your vehicle manufacturer for specific warranty coverage related to emissions components.
EGR systems have been used in vehicles for decades to reduce emissions, and issues with EGR coolers have been a common concern in diesel engines.
Moderate – While the vehicle may still be drivable, prolonged operation with this issue can lead to increased emissions and potential engine damage.
Driving with a malfunctioning EGR system can lead to failing emissions tests and increased pollution.
• Engine at operating temperature
• Vehicle idling or under light load
The EGR cooler is typically located near the engine, connected to the exhaust manifold and the intake manifold.
Q: Can I drive with a P14D0 code?
A: It's possible to drive for a short time, but it's not recommended due to increased emissions and potential engine damage.
Q: How can I prevent EGR cooler issues?
A: Regular maintenance and using high-quality fuel can help prevent issues with the EGR cooler.
Budget · Enhanced code reader
A wired color-screen reader with readiness hotkeys, live data, code definitions, and data logging.
Good for emissions-related codes because it exposes readiness monitors and live powertrain data.
