P0413
Fix within 1-2 weeksThe engine computer has detected an open circuit in the electrical system that controls your secondary air injection pump. This pump pushes fresh air into your exhaust during cold starts to help the catalytic converter warm up faster and reduce harmful emissions.
Code P0413 means your secondary air injection pump circuit is open. Common causes: SAI pump failure (60%), wiring issues (25%), relay/fuse (10%). Drivability: Yes, safe to drive. Repair cost: $5-$400 DIY, $100-$850 professional.
Can I Drive With P0413?
Yes, safe to drive
No restrictions
Stop driving immediately if: Flashing CEL (indicates severe misfire, not typical for P0413), loud noises from the engine, burning smell, significant power loss (not related to P0413).
Symptoms of P0413
- 1Check Engine Light is on
- 2No noticeable change in vehicle performance
- 3Possible slight increase in emissions during cold starts (not usually noticeable by driver)
Common Causes of P0413
Parts most likely causing this code, ranked by probability
The electric motor inside the SAI pump can fail, creating an open circuit that the engine computer detects.
60% of P0413 cases are fixed by replacing this part
Corrosion, rodent damage, or a loose connection in the wiring or connector to the SAI pump can cause an open circuit.
25% of P0413 cases are fixed by repairing wiring or connectors
A blown fuse or a faulty relay for the SAI pump will prevent power from reaching the pump, resulting in an open circuit.
10% of P0413 cases are fixed by replacing the relay or fuse
While rare, an internal fault within the engine computer could cause it to incorrectly report an open circuit for the SAI pump.
5% of P0413 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Check the fuse for the secondary air injection pump in your vehicle's fuse box. A blown fuse is a quick and cheap fix.
- Visually inspect the electrical connector and wiring leading to the secondary air injection pump for any signs of damage, corrosion, or a loose connection.
How to Diagnose P0413
- 1Check the fuse for the secondary air injection pump in your vehicle's fuse box.
- 2Visually inspect the wiring harness and electrical connector leading to the secondary air injection pump for damage, corrosion, or looseness.
- 3Locate and test the secondary air injection pump relay using a multimeter or by swapping it with a known good relay (if applicable).
- 4Disconnect the SAI pump and use a multimeter to check for continuity across the pump's terminals; an open circuit indicates an internal pump failure.
- 5With the ignition on, use a multimeter to check for voltage and ground at the SAI pump's electrical connector to ensure power is reaching the pump.
P0413 on Popular Vehicles
Chevrolet Silverado
2007-2024SAI pump failures are common, often due to water intrusion or internal motor failure. The pump is typically located near the front of the engine compartment.

Frequently Asked Questions
What does P0413 mean?
P0413 indicates that your vehicle's engine computer has detected an open circuit in the electrical system for the secondary air injection (SAI) pump. This pump is crucial for reducing emissions during cold engine starts.
Can I drive with P0413?
Yes, you can drive safely with a P0413 code. This code does not typically cause drivability issues or immediate damage. However, your vehicle will produce higher emissions during cold starts, and it's best to fix it within 1-2 weeks to prevent potential long-term catalytic converter issues.
Will P0413 clear itself?
No, P0413 will not clear itself. The Check Engine Light will remain on until the underlying electrical open circuit issue is diagnosed and repaired. Once fixed, you'll need to clear the code with an OBD-II scan tool.
How do I fix P0413 myself?
Start by checking the SAI pump fuse and relay. If those are good, inspect the wiring and connector to the pump for any damage. If the wiring is sound, you'll likely need to replace the secondary air injection pump itself, as an internal failure is a common cause for an open circuit.
How much does it cost to fix P0413?
DIY repair costs for P0413 range from $5 (for a fuse) to $400 (for a new SAI pump). Professional repair at a shop typically costs between $100 and $850, including diagnosis, parts, and labor.
P0413 keeps coming back - why?
If P0413 keeps returning, it means the root cause of the open circuit hasn't been fully resolved. This often happens if a damaged wire was overlooked, a new pump was faulty, or there's an intermittent connection issue that wasn't caught during initial diagnosis. A thorough electrical test of the circuit is needed.
Will P0413 fail emissions/smog test?
Yes, P0413 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on, regardless of the code, is an automatic failure in most jurisdictions, and the secondary air injection system is a critical emissions component.
What's the difference between P0413 and P0410?
P0413 specifically indicates an 'open circuit' in the secondary air injection pump's electrical system, meaning the computer isn't detecting a complete electrical path. P0410 is a more general code indicating a 'malfunction' in the secondary air injection system, which could be due to low air flow, a stuck valve, or other issues, not just an electrical open circuit.
P0413 on Chevrolet Silverado?
P0413 is a common code on Chevrolet Silverado trucks, often due to the secondary air injection pump failing. These pumps are sometimes prone to water intrusion, leading to internal electrical failure. Always check the fuse and relay first, but be prepared to replace the pump.
Questions to Ask Your Mechanic
Did you check the fuse and relay for the secondary air injection pump?
Good answer: Yes, I confirmed the fuse is good and the relay clicks, or I tested it with a multimeter and it's functioning correctly.
What did you find when you tested the wiring to the SAI pump?
Good answer: I performed a continuity test on the wiring harness and checked for voltage and ground at the pump connector. Everything tested good, indicating the issue is internal to the pump.

Intermediate - requires basic electrical diagnostic skills with a multimeter, but the physical replacement of the pump is usually accessible.
Cost of Waiting
Ignoring P0413 means your vehicle's emissions system isn't working correctly during cold starts. This sends more unburned fuel into your catalytic converter, which can shorten its lifespan. A $200 secondary air pump replacement now prevents a $1,000-$2,500 catalytic converter replacement later.
While You're In There...
If your vehicle uses a separate check valve, it's often located near the pump or in the air injection path. It can fail and cause related issues, and replacing it while accessing the pump can save future labor.
Tools You'll Need
- OBD-II Scan Tool
- Multimeter
- Socket Set
- Screwdriver Set
- Wire Strippers/Crimpers (if wiring repair is needed)
P0413 is a common emissions code that doesn't affect how your car drives. It's a straightforward electrical diagnosis, and most repairs are under $400, getting your emissions system back in shape.

Your Next Steps
Step 1: Check the secondary air injection pump fuse. If blown, replace it and clear the code. If it blows again, you have a short circuit.
Step 2: If the fuse is good, inspect the wiring and connector to the pump for damage. Repair any frayed wires or corroded terminals.
Step 3: Test the secondary air injection pump relay. If it's faulty, replace it. If the fuse, wiring, and relay are all good, the secondary air injection pump itself is the most likely culprit.
