Intake Air Temperature Sensor 2 Circuit High Bank 1

Where it lives

For P0098, the sensor sits on the circuit this code reports. The description of P0098 puts it on bank 1.

Check these first

• An open in the sensor 2 signal wire
• An unplugged or failed sensor 2
• High resistance at the sensor 2 connector pins
• A poor ground on the sensor 2 circuit
• A faulty ECM input

What to do next

1. Read the sensor 2 value and check for a fixed high reading
2. Inspect the sensor 2 connector for a loose or unplugged sensor
3. Test the signal wire for an open
4. Measure sensor 2 resistance against a chart
5. Replace the intake air temperature sensor 2 if it reads open
6. Clear the code and retest
