|---|---|
| Meaning | P2435: Secondary Air Injection System Air Flow/Pressure Sensor Circuit Bank 2 |
| Is it serious? | Moderate – improper functioning of this sensor may lead to inefficient emissions control and reduced engine performance. |
| Possible causes | – Issues with the air flow/pressure sensor circuit for the secondary air injection system Bank 2 – Faulty air flow/pressure sensor – Wiring or connector problems |
| How to diagnose? | – Inspect and test the air flow/pressure sensor circuit for Bank 2 – Check wiring and connectors – Replace faulty sensor if needed |
P2435 Meaning
The P2435: Secondary Air Injection System Air Flow/Pressure Sensor Circuit Bank 2 code signifies that there is an issue with the circuit monitoring the air flow or pressure in the secondary air injection system for Bank 2. This could be due to problems with the sensor itself, or it might be caused by damaged wiring or faulty connectors. This sensor helps ensure proper air flow into the exhaust to reduce emissions. If the sensor malfunctions, it can cause poor air injection management, leading to elevated emissions and reduced engine efficiency.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to determine if there are additional related codes that might help identify further issues or point to the root cause. | OBD-II Scanner |
| Inspect the Air Flow/Pressure Sensor | Visually inspect the secondary air injection air flow/pressure sensor for Bank 2 for any signs of physical damage, such as cracks, corrosion, or loose mounting. | Flashlight, Safety Gloves |
| Test the Sensor Circuit | Use a diagnostic tool to test the output from the air flow/pressure sensor and verify that the readings are within the manufacturer’s specified range. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connectors | Inspect all wiring and connectors leading to the sensor for damage, loose connections, or corrosion that could be affecting the circuit. | Flashlight, Multimeter |
| Repair or Replace Wiring | If any faults are found with the wiring or connectors, repair or replace them to restore proper functionality to the sensor circuit. | Wiring Repair Kit, Connector Tools |
| Replace the Sensor if Faulty | If the sensor itself is found to be defective, replace it to restore accurate monitoring of the air flow and pressure in the secondary air injection system. | Replacement Sensor, Wrench Set |
| Clear the Code and Test Drive | After repairs are completed, clear the P2435 code using an OBD-II scanner and perform a test drive to confirm that the issue has been resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle after the test drive to ensure that the P2435 code has not returned. If it does reappear, further diagnostic procedures may be required. | OBD-II Scanner |
