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.

Likely causes

Sensor drifting or coated with oil or soot from crankcase and exhaust gas recirculation
Contact resistance at the connector
Comparison sensor faulty
Heat soak or leak in the intake manifold

Symptoms

  • Check engine light on
  • Usually no noticeable symptoms
  • Slightly changed power or retarded ignition possible
