P0095
Intake Air Temperature Sensor 2 Circuit Bank 1
Fuel & air metering
Generic OBD-II
Low
What it means
P0095 means the engine computer sees a problem in the circuit for the second intake air temperature sensor on bank 1. This sensor measures the temperature of the air entering the engine, often after the turbo or intercooler. A bad reading can nudge fuel and timing slightly off, but the engine still runs.
Low
Can I keep driving? Usually drivable — the engine runs, though it may idle a little rough or hesitate and use slightly more fuel until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Inaccurate or erratic intake air temperature 2 readings
- Mild rough idle or hesitation
- Slightly reduced fuel economy
Common causes
Most likely first
- Open or short in the intake air temperature sensor 2 wiringLikely
- Loose or corroded electrical connector at the sensorCommon
- Faulty or damaged intake air temperature sensor 2Common
- Fault in a shared power or ground circuitLess often
- Faulty engine control module (ECM) — rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and view the live IAT 2 reading.
- At a cold key-on, compare IAT 2 to IAT 1 and ambient temperature — they should read close.
- Inspect the sensor connector and wiring for opens, shorts, or corrosion.
- Measure the sensor's resistance against a temperature chart and replace it if out of spec.
- Check any shared power/ground circuits; consider the ECM last. Clear and re-test.
