This summary uses the existing diagnostic information shown in full below.
Your car has a system that helps reduce pollution. This code means that a part of that system isn't working right because it's not getting enough power.
The P1413 code indicates a problem with the electrical circuit that controls the relay of the secondary air injection pump. The signal is lower than expected, which means there might be an issue with the power supply or the relay itself.
The secondary air injection system helps reduce emissions by pumping fresh air into the exhaust system. The relay controls the pump, and if the control circuit signal is low, it may indicate a problem with the relay, wiring, or other electrical components.
• Check Engine Light is on
• Failed emissions test
• Possible decrease in engine performance
• Faulty secondary air injection pump relay
• Blown fuse in the air injection system
• Damaged or corroded wiring or connectors
Relay: An electrical switch that opens and closes under the control of another electrical circuit.
Secondary Air Injection: A system that injects air into the exhaust stream to help reduce emissions.
• Check the fuse for the secondary air injection system.
• Inspect the wiring and connectors for damage or corrosion.
• Test the relay for proper operation.
• Replace the faulty relay.
• Repair or replace damaged wiring or connectors.
• Replace any blown fuses.
• Multimeter
• Relay tester
• Basic hand tools

Moderate
• Ford Focus
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain the air injection system.
• Keep electrical connections clean and secure.
• Replace fuses as needed.
Sensor Issue
• Address this issue promptly to avoid increased emissions.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle manufacturer for specific warranty coverage related to emissions systems.
The P1413 code has been commonly reported in vehicles with secondary air injection systems, particularly in models from the early 2000s.
Moderate – It should be addressed soon to ensure proper emissions control and vehicle performance.
Driving with a malfunctioning emissions system may violate local emissions laws and contribute to environmental pollution.
• Engine at operating temperature
• Vehicle in park or neutral
The secondary air injection pump and relay are typically located near the front of the engine bay, often on or near the fender well.
Q: What does the secondary air injection system do?
A: It helps reduce emissions by injecting fresh air into the exhaust system to help burn off excess fuel.
Q: Can I drive with a P1413 code?
A: While the car may still run, it's best to fix the issue soon to avoid increased emissions and potential engine performance issues.
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.
