P00A6 Intake Air Temperature Sensor 2 Circuit Range/Performance Bank 2

Drive cycleRequired
Limp modeNo

Intake air temperature sensor 2 for bank 2 is the second air temperature sensor in the intake path of the second cylinder bank, for example in the intake manifold behind the charge air cooler on engines with two intake paths. For P00A6, this is a plausibility check: at a start after a long standstill the sensor is compared with other temperature sensors (for example coolant temperature or the matching sensor of the other bank), which should then agree. No manufacturer description naming this exact code was found. Bank 2 codes occur only on engines with two separate intake or charge-air paths, one per cylinder bank.

Likely causes

Sensor drifting or coated with oil or soot
Contact resistance at the connector
Comparison sensor faulty
Engine block heater or auxiliary heater distorting the start comparison

Symptoms

  • Check engine light on
  • Usually no noticeable symptoms
  • Emissions test or readiness check may fail

Repair estimate

DifficultyEasyDIY possible
Parts and labour€40–250
Time0.3–2 h

Typical range across vehicles; the real cost depends on what the testing finds.
