Compare: Used OEM, Refurbished OEM, New Aftermarket

Used OEM

• Used OEM air injection pumps offer excellent value. These are genuine factory parts that have been tested and inspected to ensure they are in good working condition. You get the quality of an OEM part at a significantly lower price.

Refurbished OEM

• Refurbished OEM air injection pumps are factory parts that have been professionally restored. They may include new components and have been tested to meet performance standards.

New Aftermarket

• New aftermarket air injection pumps are brand new parts manufactured by third-party companies. They are built to meet or exceed OE specifications and offer a cost-effective alternative to OEM parts.

Parts Commonly Replaced or Checked

• Air Injection Hoses: These hoses can crack or become brittle over time, leading to leaks.
• Check Valve: A faulty check valve can allow exhaust gases to flow back into the pump, damaging it.
• Air Injection Relay: This relay controls the power to the pump.
• Oxygen Sensors: Faulty oxygen sensors can cause the engine to run rich, which can damage the air injection system.

Preventing Repeat Failures

• Replacing related parts at the same time can prevent repeat failures. For example, if the air injection hoses are cracked, they should be replaced when the pump is replaced. This will prevent exhaust gases from damaging the new pump.

How Long This Part Normally Lasts

• An air injection pump typically lasts 5-10 years or 75,000-150,000 miles.

Factors That Affect Longevity

• Driving conditions: Frequent short trips can shorten the lifespan of the pump.
• Maintenance: Regular maintenance, such as checking the hoses and connections, can extend the lifespan of the pump.
• Quality of the part: A high-quality OEM or aftermarket part will typically last longer than a low-quality part.
• Leaks in the exhaust system: Exhaust leaks can damage the pump.

Budget vs Mid-Range vs Premium Options

• Used OEM: $50 - $150
• Refurbished OEM: $100 - $250
• New Aftermarket: $150 - $350

Labor Cost Considerations

• Labor costs for replacing an air injection pump typically range from $100 to $300, depending on the shop and the complexity of the job.

Total Job Cost Estimates

• Total job cost (including parts and labor) can range from $150 to $650.

Known Issues

• Some models are prone to moisture buildup in the air injection pump, leading to premature failure.
• Check valves are known to fail on certain models, causing exhaust gases to damage the pump.

TSBs or Common Complaints

• Check for any Technical Service Bulletins (TSBs) related to the air injection system on your specific vehicle. These TSBs may provide information on common problems and solutions.

How to Confirm Proper Operation

• Start the engine and listen for the pump to activate. It should run for a short time after startup.
• Use a scan tool to check for any diagnostic trouble codes (DTCs) related to the air injection system.
• Monitor the oxygen sensor readings to ensure the system is working properly.

What to Look/Listen For

• The pump should run smoothly and quietly.
• There should be no unusual noises or vibrations.
• The Check Engine Light should be off.
• The oxygen sensor readings should be within the normal range.

Q: How do I know if my air injection pump is bad?
A: Common signs include a Check Engine Light, loud noises from the pump, failed emissions test, and poor engine performance.

Q: Can I drive my car with a bad air injection pump?
A: Yes, but it's not recommended. A faulty pump can cause your car to fail an emissions test and may affect engine performance.

Q: Is it hard to replace an air injection pump myself?
A: It's an intermediate-level job. If you're comfortable working on cars and have the right tools, you can do it yourself. Otherwise, professional installation is recommended.

Q: Will a new air injection pump fix my Check Engine Light?
A: If the Check Engine Light is caused by a faulty air injection pump, replacing it should fix the problem. However, you may need to clear the diagnostic trouble codes (DTCs) with a scan tool.

Q: How often should I replace my air injection pump?
A: An air injection pump typically lasts 5-10 years or 75,000-150,000 miles.
