Code P1413 2015 Chevrolet Silverado Description
The P1413 diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Valve Control Circuit being shorted. The EGR system in a vehicle is responsible for recirculating a portion of the exhaust gases back into the engine's intake manifold to reduce emissions and control combustion temperatures. The EGR Cooler Bypass Valve controls the flow of exhaust gases through the EGR cooler to regulate the engine's temperature.
Common Causes of P1413 2015 Chevrolet Silverado
- Electrical short in the EGR Cooler Bypass Valve Control Circuit
- Faulty EGR Cooler Bypass Valve
- Wiring harness issues or damaged connectors
- ECM malfunction or software glitch
- Corrosion or debris affecting the EGR system components
Symptoms of P1413 2015 Chevrolet Silverado
- Check Engine Light illuminated
- Reduced engine performance or power
- Rough idling or stalling
- Increased fuel consumption
- Emission-related issues, such as failed emissions tests
How to Fix P1413 2015 Chevrolet Silverado
- Begin by conducting a thorough inspection of the EGR Cooler Bypass Valve Control Circuit, including the wiring, connectors, and valve itself.
- Test the EGR Cooler Bypass Valve Control Circuit for continuity and resistance to identify the shorted component.
- Replace the faulty EGR Cooler Bypass Valve if necessary, ensuring proper installation and connection.
- Repair any damaged wiring or connectors in the circuit to restore proper electrical flow.
- Clear the DTC codes from the ECM and perform a test drive to verify that the issue has been resolved.
Cost to Fix P1413 2015 Chevrolet Silverado

Common symptoms include the Check Engine Light turning on, reduced engine power, poor fuel efficiency, and potentially higher engine temperatures.
3. What causes the P1413 code to appear?
The most common causes are a shorted or damaged EGR cooler bypass valve, wiring issues such as frayed or corroded wires, or a faulty control module.
4. Can I drive my 2015 Chevrolet Silverado with a P1413 code?
While it may be possible to drive, it is not recommended as it can lead to increased emissions, poor engine performance, and potential damage to the EGR system or engine.
5. How do I fix the P1413 code on my Silverado?
Start by inspecting the EGR bypass valve and its wiring for damage or shorts. Replace the valve or repair the wiring if needed. If the issue persists, check the control module.
6. How much does it cost to fix a P1413 code?
Repair costs can vary but typically range from $150 to $500, depending on whether the issue is with the valve, wiring, or control module.
7. Can a dirty EGR valve cause a P1413 code?
No, this code specifically relates to the EGR cooler bypass valve control circuit, not the EGR valve itself, though a malfunctioning bypass valve may affect the system.
8. How is the P1413 code diagnosed?
A mechanic will use an OBDII scanner to confirm the code, inspect the wiring and connections, test the bypass valve for function, and check the control circuit for shorts or faults.
9. Does clearing the code fix the problem?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be repaired to prevent the code from returning.
10. Can a bad PCM cause the P1413 code?
While rare, a faulty Powertrain Control Module (PCM) can cause this code if it fails to properly control the EGR bypass valve.
