This summary uses the existing diagnostic information shown in full below.
The car's air pump, which helps reduce pollution, is stuck on and won't turn off on one side of the engine.
The P2444 code indicates that the secondary air injection pump is continuously running on bank 1, which is the side of the engine with cylinder 1.
The secondary air injection system is designed to reduce emissions by injecting air into the exhaust stream to help burn off excess fuel. The system includes an air pump, valves, and hoses. Code P2444 is triggered when the powertrain control module (PCM) detects that the air pump is continuously running when it should not be, indicating a possible electrical or mechanical fault.
• Check Engine Light is on
• Increased emissions
• Possible engine performance issues
• Faulty air injection pump relay
• Stuck open air injection pump
• Wiring issues such as shorts or opens
PCM: Powertrain Control Module
Bank 1: The side of the engine with cylinder 1
• Scan the vehicle for codes and freeze frame data.
• Inspect the air injection pump relay for faults.
• Check the wiring and connectors for damage or corrosion.
• Replace the faulty air injection pump relay.
• Repair or replace damaged wiring or connectors.
• Replace the air injection pump if it is stuck on.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Chevrolet Silverado
• BMW 3 Series
• Regular maintenance and inspection of the air injection system
• Ensure proper electrical connections
• Avoid driving through deep water which can damage the pump
Emission Control System Issue
• Address the issue promptly to avoid increased emissions.
• Consult a professional mechanic if unsure about repairs.
Check with the vehicle manufacturer for emissions-related warranty coverage.
This code has been more common in vehicles with aging secondary air injection systems.
Moderate – While the vehicle may still be drivable, emissions will be affected, and it should be repaired to pass emissions tests.
Operating a vehicle with this code may result in failing emissions tests and is not environmentally friendly.
• Engine at operating temperature
• Vehicle running in closed loop mode
The secondary air injection pump is typically located near the front of the engine or under the vehicle, depending on the make and model.
Q: Can I drive with a P2444 code?
A: Yes, but it's not recommended due to increased emissions and potential for further damage.
Q: What happens if I ignore the P2444 code?
A: Ignoring the code can lead to increased emissions, potential engine performance issues, and failing emissions tests.
