P00EB medium Severity

P00EB: Intake Air Temperature Sensor 3 Circuit High (Bank 1)

Potential incorrect air temperature data leading to altered fuel metering and reduced performance

Overview

OBD‑II P00EB indicates Intake Air Temperature (IAT) Sensor 3 Circuit High for Bank 1, usually caused by sensor or wiring fault, affecting air temperature input to ECM

Common Symptoms

  • Check Engine Light illuminated
  • Incorrect intake air temperature readings
  • Poor idle or performance
  • Possible rough running under load

Most Common Causes

Faulty Intake Air Temperature Sensor 3 high

Sensor output voltage too high indicating malfunction or internal fault

Open or shorted sensor wiring harness medium

Circuit may be shorted to voltage or high resistance/open causing high voltage reading

Poor electrical connection at sensor or ECM medium

Connector corrosion, bent pins, or poor contact can lead to abnormal circuit readings

ECM internal fault low

Rare, but possible if other causes are ruled out

Diagnostic Steps

  1. Connect OBD‑II scanner and confirm code P00EB
    Expected: P00EB present in ECM memory
    Interpretation: Verifies fault code before further diagnosis
  2. Visually inspect IAT Sensor 3 and wiring harness for damage/corrosion
    Expected: No damaged wires, clean secure connectors
    Interpretation: Damaged harness would indicate possible cause
  3. Measure sensor signal voltage with key ON, engine off
    Expected: Voltage within expected range (typically between ~0.1V and ~4.8V)
    Interpretation: Voltage above normal indicates high circuit condition triggering code
  4. Check continuity/resistance of wiring from sensor to ECM
    Expected: Low resistance with no opens/shorts
    Interpretation: High resistance or short to B+ indicates wiring fault
  5. Replace sensor and clear code
    Expected: Sensor output returns to normal and code does not reappear
    Interpretation: Confirms sensor was cause if code gone

Repair Solutions

Replace Intake Air Temperature Sensor 3 medium
Estimated Cost: $50 - $150

OEM or quality aftermarket sensor recommended

Repair or replace damaged wiring/connectors medium
Estimated Cost: $20 - $120

Costs vary based on extent of wiring damage

ECM repair or reprogram (if needed) hard
Estimated Cost: $300 - $1000

Considered only after all sensor and wiring checks fail

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Confusing P00EB with generic intake air temperature (IAT) sensor codes like P0113 without checking specific circuit definitions

Frequently Asked Questions

Technical definition of P00EB OBD-II Code
