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.

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.

FAQ

Quick answers

Is it safe to drive with P0095?+

Usually yes. The engine keeps running, though air/fuel adjustments may be slightly off, so it's worth fixing to keep economy and idle smooth.

Can I just clear P0095?+

You can, but it returns until the wiring, connector, or sensor causing the fault is repaired.
