What is P00E4?

DTC P00E4 is a diagnostic trouble code that indicates a problem with the engine's air intake temperature sensor. This code is often triggered when the Engine Control Module (ECM) detects an abnormal reading from the intake air temperature sensor, which can lead to performance issues. When this code appears, it indicates that the temperature of the air entering the engine is not within the expected range. This can affect fuel efficiency, engine performance, and emissions. A common symptom of P00E4 is the check engine light illuminating on your dashboard. If left unaddressed, this issue can lead to increased fuel consumption and higher emissions, potentially causing your vehicle to fail emissions tests. It’s crucial to diagnose and rectify the problem promptly to ensure optimal vehicle performance. Understanding this code is essential for car owners, especially those driving models like the 2015-2018 Honda Civic, which are known to occasionally experience this issue. In many cases, resolving the P00E4 code involves checking the intake air temperature sensor and related wiring for damage or malfunction.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P00E4 is present:

  • The check engine light remains illuminated, indicating a persistent issue that needs attention.
  • Engine performance issues such as hesitation during acceleration, which can be frustrating during driving.
  • Notable decrease in fuel economy, often by 10-15%, leading to increased costs at the pump.
  • Unusual engine noise or rough idling, which can be indicative of underlying issues.
  • Increased emissions, which may cause your vehicle to fail emissions tests if not resolved.

Possible Causes

Most common causes of P00E4 (ordered by frequency):

  1. The most common cause of DTC P00E4 is a faulty intake air temperature sensor, which has a likelihood of around 70%. This sensor can wear out over time due to exposure to high temperatures and contaminants.
  2. Another cause could be damaged wiring or connectors associated with the intake air temperature sensor. This can lead to poor connectivity and erroneous readings sent to the ECM.
  3. If the vehicle has recently experienced an intake manifold leak, this can also trigger P00E4. Regular inspections can prevent this issue by ensuring proper sealing.
  4. Less commonly, a malfunctioning ECM or software glitch can cause this error code. This is rare but may require a software update or replacement of the ECM.
  5. In very rare cases, a clogged air filter can affect air flow and lead to incorrect temperature readings, contributing to the P00E4 code.
