This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble understanding the information from a part of the engine that helps reduce pollution.
The EGR (Exhaust Gas Recirculation) system helps reduce emissions by recirculating a portion of the exhaust gases back into the engine cylinders. The 'D' sensor in this system is not providing expected readings.
The P2383 code indicates that the EGR Sensor D is not operating within the expected range or performance levels. This could be due to a fault in the sensor itself, wiring issues, or problems with the EGR valve or system.
• Check Engine Light is on
• Poor engine performance
• Increased emissions
• Faulty EGR Sensor D
• Wiring issues or poor connections in the EGR circuit
• Malfunctioning EGR valve

• Inspect the wiring and connections to the EGR Sensor D
• Test the EGR Sensor D for proper operation
• Replace faulty EGR Sensor D
• Repair or replace damaged wiring or connectors
• Replace or clean the EGR valve if necessary
• OBD-II scanner
• Multimeter

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance and inspection of the EGR system
• Ensure quality fuel is used
• Regularly clean the EGR valve
Sensor Issue
• Have a professional diagnose the issue if you're unsure
• Do not ignore the Check Engine Light
• Consider regular emissions system checks
Check with your vehicle manufacturer for specific warranty coverage on emissions-related components.
EGR system issues have been common in vehicles as emissions standards have become stricter.
Moderate – Addressing this code is important to maintain vehicle performance and emissions compliance.
Ignoring emissions-related issues can lead to failing emissions tests and potential fines.
• Engine at operating temperature
• Vehicle in closed-loop operation
The EGR sensor is typically located near the EGR valve, which is often mounted on the intake manifold.
Q: Can I drive with a P2383 code?
A: It's possible to drive short distances, but it's best to fix the issue soon to avoid increased emissions and potential engine damage.
Q: Will a faulty EGR sensor affect fuel economy?
A: Yes, a malfunctioning EGR system can lead to decreased fuel efficiency.
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.
