AIR System Air Flow/Pressure Sensor Circuit Range/Performance Bank 2

Where it lives

For P2436, the part to look at first is the sensor named here. The description of P2436 puts it on bank 2.

Check these first

• A bank 2 AIR pressure reading outside its expected range
• A restriction in the bank 2 secondary air supply
• High resistance in the sensor circuit
• A failing bank 2 AIR air flow/pressure sensor

What to do next

1. Read bank 2 AIR air flow/pressure on a scan tool
2. Compare the reading to the commanded air pump state
3. Inspect the bank 2 secondary air supply for restriction
4. Measure resistance of the sensor circuit
5. Replace the bank 2 AIR air flow/pressure sensor if the supply tests good
6. Clear the code and retest
