P00E7 medium Severity

P00E7: Intake Air Temperature Measurement System – Multiple Sensor Correlation Bank 2

Possible incorrect air-fuel mixture leading to reduced performance and efficiency

Overview

OBD-II P00E7 is a generic powertrain code indicating an intake air temperature (IAT) measurement system fault involving multiple sensor correlation on engine bank 2

Common Symptoms

  • Check engine light illuminated due to intake air temperature correlation fault
  • Reduced engine performance or hesitation in acceleration
  • Possible rough idle or decreased fuel efficiency

Most Common Causes

Faulty intake air temperature (IAT) sensor Bank 2 high

Incorrect or inconsistent temperature readings from IAT sensor can trigger P00E7 by failing correlation checks between sensors and expected values

Wiring harness or connector issues (loose, corroded, open/short) medium

Poor electrical connection between the IAT sensor and ECU can cause sporadic or invalid sensor data

Intake air leaks affecting sensor readings medium

Unmetered air entering system may cause variable temperature readings that do not correlate with other sensors

Engine control module (ECM) misinterpretation or software anomaly low

Less common, but possible if software has issues interpreting sensor correlation

Diagnostic Steps

  1. Confirm code with OBD-II scan tool and record any freeze-frame data
    Expected: P00E7 status present and consistent
    Interpretation: Validates that the fault is currently stored in powertrain system
  2. Visually inspect intake air temperature sensor Bank 2 and connectors
    Expected: No damage, secure connectors, no corrosion
    Interpretation: Damaged sensor or connectors likely contributing to invalid readings
  3. Check wiring harness continuity between IAT sensor and engine control module
    Expected: Continuity within manufacturer specifications
    Interpretation: Open/short wiring can cause incorrect signals and code triggering
  4. Measure sensor resistance/voltage with multimeter at different temperatures
    Expected: Resistance/voltage varies per expected thermistor characteristics
    Interpretation: Sensor outside expected range indicates a faulty IAT sensor
  5. Clear code and perform test drive after repairs
    Expected: P00E7 does not reappear
    Interpretation: Confirms successful remedy

Repair Solutions

Replace faulty intake air temperature (IAT) sensor Bank 2 easy
Estimated Cost: $40 - $150

Typical cost range includes part and basic labor where applicable

Repair or replace damaged wiring/connectors medium
Estimated Cost: $50 - $200

Cost will vary depending on damage extent and labor rates

Estimated Cost: $100 - $300

Includes diagnosing intake paths and replacing gaskets or hoses

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Misinterpreting the code as a coolant temperature or engine overheating issue due to similar numeric designation in less authoritative sources
