P00E7Intake Air Temperature Measurement System - Multiple Sensor Correlation Bank 2

P00E7 indicates that the engine control module has detected an implausible relationship among the intake air temperature sensors on bank 2, meaning the readings from multiple sensors disagree beyond a calibrated threshold. The computer compares these signals during key-on and running conditions to verify that all bank 2 intake air temperature measurements correlate within an expected range.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Rough idle or hesitation during acceleration if the faulty sensor causes an excessively rich or lean condition
Poor fuel economy due to incorrect air density calculations
Intermittent stalling or hard starting in extreme temperatures
A slight decrease in engine performance, especially under heavy load

Common causes, most likely first

Faulty intake air temperature sensor on bank 2
Damaged or corroded wiring or connector at the bank 2 intake air temperature sensor
Open or short circuit in the sensor signal or ground circuit
Failed mass airflow sensor that incorporates the intake air temperature sensor on bank 2
Engine control module software calibration issue or internal fault
Intake air leaks or restrictions affecting only bank 2

How to diagnose and fix it

Connect a scan tool and record freeze-frame data and all intake air temperature sensor readings to confirm the discrepancy
Visually inspect the bank 2 intake air temperature sensor and its connector for damage, corrosion, or loose pins
Measure resistance across the sensor terminals and compare with the manufacturer's temperature-resistance chart
Check the sensor signal and ground circuits for opens, shorts, or excessive resistance using a multimeter
Verify that the mass airflow sensor and other shared sensors are functioning correctly, as they can influence the correlation
If all electrical checks pass, reflash or replace the engine control module only after confirming no other faults exist

When bank 2 sensors disagree

A common oversight is replacing the intake air temperature sensor when the real problem is a failing mass airflow sensor that houses the bank 2 sensor, so always test the entire assembly.
The code can set intermittently due to a poor connection that only acts up under vibration or temperature changes, so wiggle-test the harness while watching live data.
Some vehicles use a modeled intake air temperature value derived from other sensors, and a fault in those sensors can trigger P00E7 even if the physical sensor is good.
After repairs, the code may not clear immediately because the monitor requires a specific drive cycle with a cold soak, so follow the manufacturer's readiness procedure.
A dirty or restricted air filter or intake tract on bank 2 can cause temperature stratification that leads to correlation errors, so inspect the intake system before condemning sensors.

Can I keep driving with P00E7?

The vehicle is generally safe to drive with P00E7 because the fault typically affects fuel economy and emissions rather than immediate safety, but avoid heavy acceleration or towing until diagnosed. Prolonged driving with a faulty sensor can lead to catalytic converter damage over time, so schedule repairs promptly.
