P0096Intake Air Temperature Sensor 2 Circuit Range/Performance Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- Intake air temperature sensor 2 is the second air temperature sensor in the intake path. On many turbocharged engines it sits in the intake manifold behind the compressor and charge air cooler, often combined with the manifold pressure sensor, and is used to calculate cylinder filling and ignition timing. The numbering is not standardised, so its position can differ between manufacturers. P0096 is a plausibility check: at a start after a long standstill the sensor is compared with intake air temperature sensor 1 and others, which should then agree; some systems also flag implausibly high readings while driving. A sensor stuck at one value is detected this way.
- What you may notice
- Check engine light on
- Usually no noticeable symptoms
- Slightly changed power or retarded ignition possible
- Likely causes
- LikelySensor drifting or coated with oil or soot from crankcase and exhaust gas recirculation
- PossibleContact resistance at the connector
- PossibleComparison sensor faulty
- RareHeat soak or leak in the intake manifold
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €70 – €220
