2021-2023 Honda Models CEL On DTC P0087 Stored

Background: Honda Investigates DTC P0087 and Engine Starting Issues

American Honda Motor Co., Inc. (AHM) is actively investigating a condition affecting certain 2021-2023 Honda Accord, CR-V, Odyssey, Passport, Pilot, Ridgeline, and Civic models. This investigation focuses on vehicles where the "Check Engine Light (CEL) on" is illuminated and the diagnostic trouble code (DTC) P0087, indicating "Fuel Rail Pressure Too Low (Loss of Fuel Pressure)", is stored.

AHM's objective is to thoroughly understand the root cause of this condition before any repairs are attempted. This proactive approach ensures that any future solutions are effective and address the underlying problem. If your Honda Civic P0087 is stored, or you experience related symptoms, your vehicle may be part of this investigation.

Symptoms Owners May Experience

Owners of affected 2021-2023 Honda vehicles may observe several symptoms related to this fuel pressure issue. The most prominent symptom is the illumination of the "Check Engine Light (CEL) on" on the dashboard. Beyond the warning light, drivers might also encounter:

• Engine hard to start: The engine may crank for an extended period before starting.
• No start: In some cases, the engine may fail to start altogether.
• Start & stumble: The engine might start but then run roughly or hesitate, particularly during initial operation.

These symptoms are often observed in conjunction with the "Check Engine Light (CEL) on", signaling a potential problem with the fuel system's pressure.

Fault Codes (DTCs)

The primary fault code under investigation for this condition is:

Code	Description	Associated Condition
P0087	Fuel Rail Pressure Too Low / Loss of Fuel Pressure	Check Engine Light (CEL) on, engine starting issues

This DTC specifically points to an issue where the fuel pressure in the rail is below the expected threshold, which can severely impact engine performance and reliability.

Diagnosis and Trigger Conditions for Investigation

For a vehicle to be considered for AHM's investigation, it must meet specific criteria. These qualifiers help AHM gather relevant data from vehicles exhibiting the precise symptoms and conditions they are studying. If your vehicle presents with the "Check Engine Light (CEL) on" and DTC P0087, your dealer will check the following:

• Confirmation that DTC P0087 stored is present in the vehicle's computer system.
• Verification that the fuel pressure on the low-pressure fuel system is out of spec.
• The vehicle must be physically present at the dealership when the case is reported.
• Crucially, no repair has been attempted for this issue prior to the investigation.

These conditions ensure that AHM can inspect the vehicle in its original fault state to better understand the cause of the problem.

Important Warnings for Owners

Owners of affected 2021-2023 Honda models should be aware of specific instructions from American Honda regarding this issue. The manufacturer communication, NHTSA ID 10229686, explicitly states that no repair has been attempted for this issue before the vehicle is considered for the investigation. This means that if you are experiencing the symptoms described, it is important not to authorize any repairs for this specific condition until your dealer has contacted AHM's Technical Information & Support (TIS) group.

This communication is primarily directed at Honda dealership personnel, not directly to consumers. Therefore, owners will not receive a direct notification from Honda about this investigation. The purpose is for AHM to inspect vehicles to understand the cause of the condition before any repair attempts are made. Dealers are instructed to email TIS with specific vehicle information if a vehicle meets the qualifiers.

Next Steps for Owners

If you own a 2021-2023 Honda Accord, Civic, CR-V, Odyssey, Passport, Pilot, or Ridgeline and are experiencing a "Check Engine Light (CEL) on" along with symptoms like "engine hard to start", "no start", or "start & stumble", it is recommended to contact your authorized Honda dealership. Inform them that you are experiencing these symptoms and that you believe your vehicle may be affected by the condition described in Manufacturer Communication NHTSA ID 10229686, which involves DTC P0087.

Your dealer will be able to confirm if your vehicle meets the specific qualifiers for AHM's investigation. If it does, they will coordinate with AHM's Technical Information & Support team for further instructions, potentially leading to an inspection of your vehicle by the manufacturer.
