Code P00A9 is frustrating because it comes and goes, indicating an intermittent signal from the Intake Air Temperature Sensor 2 on Bank 2. Your car might run fine one minute and then hesitate or surge the next as the computer struggles to calculate the right fuel mixture. This video focuses on finding those hard-to-spot issues like loose wiring, worn insulation, or dirty connector pins. I explain how to use a scan tool to watch for sudden, unrealistic spikes in temperature data while you physically move the harness. This wiggle test is the best way to replicate the failure in your driveway. We also talk about cleaning the contacts and verifying that the sensor is not vibrating loose. By following these checks, you can stop the erratic idle and restore proper engine performance without paying a shop to chase a ghost code on your vehicle.
