2014-2024 Honda Odyssey Fuel Pump: Recall Failures and Replacement Guide

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

The most significant issue affecting the 2014-2024 Honda Odyssey fuel pump is a widespread safety recall. Understanding this recall is critical before diagnosing or purchasing a replacement part.

Massive Fuel Pump Safety Recall (NHTSA Campaign 23V858000)

• Affected Years: The recall includes 2014-2020 and 2018-2023 Honda Odyssey models, covering nearly the entire range of this guide.
• The Defect: The fuel pump motor contains a plastic impeller that may have been improperly molded. Over time, this impeller can deform and swell, causing the fuel pump to seize and stop working.
• The Consequence: A failed fuel pump will prevent the engine from running, which can cause a sudden loss of power or an engine stall while the vehicle is in motion.
• The Fix: Honda dealers will replace the fuel pump module with an improved part, free of charge. You can check if your specific vehicle is affected by entering your VIN on the NHTSA or Honda recall websites.

Symptoms of a Failing Fuel Pump

Before the fuel pump fails completely, it often provides warning signs. Recognizing these symptoms can help you address the issue before you're left stranded.

• Engine Stalling or Sputtering: The engine may stall, especially when it's warm or under load. You might also notice sputtering at highway speeds as the pump struggles to supply enough fuel.
• Difficulty Starting: The engine may crank for an extended period before starting, or it may not start at all. This can happen because the pump isn't building enough pressure in the fuel lines.
• Loss of Power and Poor Acceleration: The vehicle may feel sluggish and unresponsive when you press the gas pedal. This is a classic sign of fuel starvation.
• Whining Noise from the Fuel Tank: A noticeable high-pitched whining or humming sound from the rear of the vehicle 🎬 See how to replace a faulty Honda fuel pump (where the fuel tank is located) can indicate the fuel pump motor is straining and about to fail.
• Check Engine Light: A failing fuel pump can cause a lean running condition, which may trigger a Diagnostic Trouble Code (DTC) like P0087 (Fuel Rail/System Pressure - Too Low) and illuminate the Check Engine Light.

Buying a Used 2014-2024 Odyssey Fuel Pump

Purchasing a used OEM fuel pump can be a cost-effective solution, especially compared to the high price of a new dealer part. However, due to the generation split and the major recall, it's crucial to buy smart.

Compatibility is Key: Two Generations, Two Different Pumps

The 2014-2024 Odyssey range spans two distinct generations, and they use different fuel pump assemblies. You must install the correct part for your vehicle's year.

• 2014-2017 Honda Odyssey (4th Generation): Uses part numbers beginning with 17045-TK8-. The latest version is 17045-TK8-A11, which supersedes 17045-TK8-A10.
• 2018-2024 Honda Odyssey (5th Generation): Uses part numbers beginning with 17045-THR-. The latest version is 17045-THR-A04, which supersedes 17045-THR-A00, 17045-THR-A01, 17045-THR-A02, and 17045-THR-A03.

Inspection Checklist for a Used Fuel Pump

• Check the Part Number: This is the most important step. Ensure the number stamped on the pump housing matches the compatible numbers for your Odyssey's generation.
• Inspect the Electrical Connector: Look for any signs of corrosion, melting, or damaged pins on the main electrical connector. A damaged connector indicates a potential electrical issue that could have stressed the pump.
• Examine the Housing: Check the plastic housing for any cracks, deep scratches, or signs of warping. The unit should be intact and solid.
• Verify the Source Vehicle: If possible, get the VIN of the vehicle the pump came from. This allows you to check its recall history to see if the recall was performed. A pump from a vehicle that has had the recall completed is a much safer bet.
• Why Used OEM is Often Better: A used original Honda (OEM) fuel pump, especially one made after the recall period, is often a more reliable choice than a cheap, new aftermarket part. OEM parts are built to stricter quality standards and are designed to integrate perfectly with your vehicle's systems.
