Intake Air Temperature Sensor 2 Circuit Low Bank 1

Where it lives

For P0097, the circuit described runs through the sensor. The description of P0097 puts it on bank 1.

Check these first

• A short to ground on the sensor 2 signal wire
• A sensor 2 with low resistance
• Water in the sensor 2 connector pulling the signal low
• A chafed harness shorting against the engine
• A faulty ECM input

What to do next

1. Read the sensor 2 value and check for a fixed low reading
2. Inspect the sensor 2 connector for water or corrosion
3. Test the signal wire for a short to ground
4. Measure sensor 2 resistance against a chart
5. Replace the intake air temperature sensor 2 if the resistance is low
6. Clear the code and retest
