What it means
The intake air temperature readings for bank 2 do not correlate as expected. The code does not identify which sensor, if any, is faulty.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
The intake air temperature measurement system compares multiple temperature readings for bank 2. P00E7 sets when those bank 2 readings do not correlate as expected; it does not identify which sensor, connection, or airflow condition is responsible.
Common causes
Most likely first.
- One intake air temperature sensor reading incorrectly
- Damaged wiring or poor connector contact at a temperature sensor
- Airflow or temperature conditions causing inconsistent readings
Symptoms
- Check-engine light on
- Reduced engine performance or power
- Poor fuel economy
How to diagnose it
- Review freeze-frame and live temperature data for the bank 2 sensors, comparing readings under the same operating conditions.
- Inspect the bank 2 temperature sensors and their connectors for loose pins, corrosion, damaged wiring, or poor mounting.
- Check the bank 2 intake path for airflow conditions or heat exposure that could make the temperature readings differ.
- Test the relevant bank 2 sensor circuits for opens, shorts, and poor connector contact using the vehicle wiring information.
- If the wiring and airflow checks pass, test the bank 2 sensors against the manufacturer’s specification to find the inconsistent reading.
Common fixes
- Repair damaged wiring or poor connector contact at the affected bank 2 temperature sensor.
- Secure a loose sensor or restore its proper mounting if it is disrupting the reading.
- Correct an intake airflow or heat exposure issue affecting bank 2 readings.
- Replace the bank 2 temperature sensor that fails testing.
Can I keep driving?
If the engine runs normally, you can generally make a short, gentle drive, though inaccurate bank 2 temperature data may reduce power or fuel economy. Avoid heavy loads if performance is affected and arrange diagnosis soon.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
