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

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.

Low severity. Can I keep driving?Yes, you can normally keep driving and take it to a repair shop when convenient.

Bank 2 is the side without cylinder 1, so it only exists on V or boxer engines.

Symptoms

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

Most 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

What to check, in order

Start with the simplest. You can tick off each step.

Good to know

  • Repair difficulty: easy
  • It affects emissions.

What each character of P00A6 means

  • P: Powertrain: engine and transmission
  • 0: Generic code: same on every make
  • 0: Subsystem depends on the code range
  • A6: Specific fault in that system
