P00AE: Intake Air Temperature Sensor 1 Circuit Intermittent Bank 2

What does P00AE mean?

Intake air temperature sensor 1 for bank 2 measures the intake air temperature in the second intake path, typically near the air filter or in the air flow meter of that bank, on engines with two separate intake paths. For P00AE, the signal jumps faster than a real temperature can change, which typically points to a loose contact. 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.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

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

Common causes

• High Loose contact or wire broken by movement
• Medium Sensor failing intermittently
• Low Interference on the signal wire

Likelihood is a general estimate across vehicles; your make and model may differ.
