P00ED medium Severity

P00ED: Intake Air Temperature Sensor 3 Circuit Bank 2 Fault

May cause incorrect air temperature readings leading to altered fuel/air mixture and rough running

Overview

OBD‑II powertrain code indicating a fault in the intake air temperature (IAT) sensor 3 circuit on bank 2.

Common Symptoms

  • Illuminated check engine light
  • Poor engine performance or hesitation
  • Rough idle
  • Potential reduced fuel economy

Most Common Causes

Faulty intake air temperature sensor 3 (Bank 2) medium

Common failure mode in older/high‑mileage vehicles

Damaged or shorted wiring/connectors in IAT 3 circuit medium

Wiring insulation wear, rodents, or connector corrosion

Faulty engine control module (ECM) input for IAT sensor 3 low

Less common but possible if sensor and wiring test good

Diagnostic Steps

  1. Retrieve freeze‑frame data and confirm the code is current
    Expected: P00ED stored or pending
    Interpretation: Confirms current fault condition
  2. Visually inspect the IAT sensor 3 (Bank 2) wiring and connectors
    Expected: No breaks, corrosion, or shorts
    Interpretation: Damaged wiring/connectors could trigger the code
  3. Measure voltage/resistance at the IAT 3 sensor circuit
    Expected: Specifications per service manual
    Interpretation: Out‑of‑spec values indicate sensor or harness issue
  4. Swap or substitute known good IAT sensor (if accessible)
    Expected: Code clears if sensor was faulty
    Interpretation: Validates sensor as root cause
  5. Test ECM input and outputs if previous steps pass
    Expected: Correct signals from ECM
    Interpretation: ECM fault if signals abnormal

Repair Solutions

Replace faulty intake air temperature sensor 3 (Bank 2) easy
Estimated Cost: $50 - $150

Part cost varies by vehicle make/model

Repair or replace damaged wiring/connectors medium
Estimated Cost: $20 - $200

Depends on extent of wiring damage

ECM repair or reprogramming hard
Estimated Cost: $300 - $1200

Only after all sensor/harness tests pass

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Interpreting code as coolant or general temperature sensor fault
  • Assuming generic ‘air intake issue’ without targeted sensor circuit testing

Frequently Asked Questions

What does the P00ED code mean?

When your OBD-II scanner reads P00ED, it means: Intake Air Temperature Sensor 3 Circuit Bank 2 Fault. This code is related to the vehicle's Air Intake.

Can P00ED cause engine damage?
