What is P098E?

The Diagnostic Trouble Code (DTC) P098E signifies a problem with the transmission fluid temperature sensor circuit 'B'. This code is typically triggered when the Engine Control Module (ECM) detects an abnormal reading from the transmission fluid temperature sensor, which can lead to severe transmission issues if left unaddressed. When your car throws this code, it indicates that the temperature of the transmission fluid is either too high or too low, which can affect shifting performance and overall drivability. In practical terms, this means you might experience rough shifting, slipping, or even complete failure to shift into certain gears. If you own a vehicle like a 2015-2018 Honda Accord or a 2016-2018 Ford Fusion, you may notice other symptoms like the check engine light illuminating or reduced fuel efficiency. Ignoring this code can lead to extensive and costly repairs, potentially leading to a complete transmission rebuild or replacement. Therefore, understanding what this code means and how to address it is crucial for maintaining your vehicle’s health and performance.

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

Symptoms

Common symptoms when P098E is present:

  • The check engine light stays on constantly, indicating a persistent issue that needs attention.
  • You may feel engine hesitation during acceleration, which can be dangerous when merging onto highways.
  • Fuel economy may decrease by 10-15%, leading to more frequent trips to the gas station.
  • Rough or delayed shifting can occur, making it feel like the transmission is struggling to engage the correct gear.
  • Overheating of the transmission fluid may be noticeable, with potential burning smells or fluid leaks.

Possible Causes

Most common causes of P098E (ordered by frequency):

  1. The most common cause of P098E is a faulty transmission fluid temperature sensor, which has a likelihood of around 70%. This sensor can fail due to wear and tear over time or exposure to extreme heat.
  2. Another possible cause is damaged wiring or poor connections within the sensor circuit, often resulting from corrosion or vibration. This issue accounts for about 20% of cases.
  3. A less common cause is low transmission fluid levels, which can lead to overheating. Regular fluid checks can prevent this from occurring.
  4. In rare cases, a malfunctioning Engine Control Module (ECM) could lead to false readings, but this is less frequent.
  5. Transmission fluid contamination due to debris or old fluid can also trigger this code, making regular maintenance crucial.
