2022-2024 Hyundai Ioniq 5 P0A2F EOP Inspection TSB

Hyundai has released Technical Service Bulletin (TSB) 24-EV-003H to address a specific condition affecting certain 2022-2024 Hyundai Ioniq 5 (NE1) and 2023 Hyundai Ioniq 6 (CE1) vehicles. Owners may experience a "Power is limited" message displayed in the instrument cluster, along with the illumination of the power down warning light, which is depicted by a turtle symbol. This issue can also be accompanied by the diagnostic trouble code (DTC) P0A2F.

This TSB outlines a detailed inspection procedure for the Electric Oil Pump (EOP) to diagnose and resolve the underlying cause of these symptoms. The Hyundai Ioniq 5 P0A2F issue, as well as the related symptoms in the Ioniq 6, points towards potential EOP malfunction.

Symptoms

Owners of affected vehicles may observe the following indicators:

• A "Power is limited" message appearing in the vehicle's instrument cluster.
• Illumination of the power down warning light, represented by a turtle symbol.

Fault Codes / DTCs

The primary diagnostic trouble code associated with this condition is:

Code	Description
P0A2F00	Electric Oil Pump (EOP) Performance Problem

Diagnosis and Trigger Conditions

To accurately diagnose the Hyundai Ioniq 5 P0A2F issue, technicians are instructed to follow a specific procedure. This involves checking for the presence of DTC P0A2F00, either current or in history. If the power down warning light is active without an accompanying DTC, further diagnosis is required.

The core of the diagnosis involves using the Global Diagnostic System (GDS) to monitor the Electric Oil Pump's operation. Key parameters to observe include: Traction motor temperature, EOP speed command, EOP speed, and EOP error data 2. The traction motor must be warmed up to ensure an EOP speed command is generated, allowing for a proper inspection. The vehicle should then be driven with repeated rapid acceleration and deceleration while monitoring the EOP speed via GDS.

Repair Procedure Summary

The repair procedure outlined in TSB 24-EV-003H involves several steps to identify and rectify the EOP issue:

1. DTC Inspection: Check for the presence of DTC P0A2F00. If present, proceed to step 3. If not, check for the power down warning light without a DTC and proceed to step 3 if present, otherwise refer to the shop manual.
2. GDS Monitoring Setup: Start the vehicle and use GDS to select specific parameters for monitoring EOP operation.
3. Traction Motor Warm-up: Drive the vehicle to warm up the traction motor. This is crucial for generating an EOP speed command.
4. EOP Operation Check: Drive the vehicle with rapid acceleration and deceleration while observing the EOP speed on GDS.
5. EOP Replacement Decision: If the EOP speed remains at 0 RPM (indicated as 'A' in the TSB's visual guide) while an EOP speed command is present (indicated as 'B'), this signifies that the EOP is not functioning correctly and requires replacement. If the EOP speed appears normal (above 0 RPM), the EOP does not need replacement, and further diagnosis should be conducted using the shop manual.

Required Parts

If the Electric Oil Pump (EOP) is determined to be faulty and requires replacement, the following part is specified:

• Part Name: EOP Assembly
• Part Number: 46120-18100

Important Warnings for Owners

Owners should be aware of specific conditions and limitations related to this TSB:

• "This TSB does not apply to Kona EV (OS EV), Ioniq Electric (AE EV), or Nexo (FE) vehicles as they are not equipped with an electric oil pump."
• "Repairs on IONIQ 5 and IONIQ 6 vehicles can only be performed by IONIQ certified dealers."
• "If the EOP is out of warranty and requires replacement, submit a Prior Approval request for goodwill consideration prior to perfoming the work."

Owner Action

If you experience a "Power is limited" message, the power down warning light, or suspect a Hyundai Ioniq 5 P0A2F issue in your 2022-2024 Hyundai Ioniq 5 or 2023 Hyundai Ioniq 6, it is recommended to contact an authorized Hyundai dealer. Repairs related to this TSB are typically covered under the vehicle's normal warranty. However, if your vehicle is out of warranty, the dealer may need to submit a Prior Approval request for goodwill consideration before performing any work.
