P0087 on Toyota

The in-tank low-pressure fuel pump supplied by Denso uses a resin impeller that was molded with too low a density. The impeller absorbs gasoline, swells and deforms, then cracks and contacts the pump housing, which stops the pump. On the XX50 Avalon this produces a rough-running engine, warning lights, and eventually a stall at speed with a no-restart condition. NHTSA campaign 20V-012 (Toyota campaign 20TA02) covered the 2019 Avalon and was later expanded to additional model years and models; the overall Denso pump action grew to cover roughly 696,000 Toyota and Lexus vehicles at first and millions across successive expansions. Owners report the failure comes on suddenly rather than after a long warning period.

The in-tank low-pressure fuel pump in the C-HR can fail due to a defective impeller that deforms and contacts the pump housing. This causes reduced fuel delivery, resulting in rough running, hesitation, and potential engine stall. Toyota issued a recall (21V-251) for a related fuel pump issue affecting multiple models including the C-HR.

Toyota's Denso low-pressure fuel-pump recall history includes certain 2018-2020 Camry vehicles under original NHTSA recall 20V012 / Toyota 20TA02 and a small omitted population of 2018 Camrys under 25V028 / 25TA01. An affected pump can stop operating, causing warning messages, rough running, engine stall and inability to restart; a stall at higher speed increases crash risk. Applicability depends on the VIN and specific pump population, not model year alone. The prior 2021 scope and recall numbers 20V750/21V251 were incorrect.

Certain 2018-2020 Corollas have a low-pressure fuel pump with an impeller that can deform due to excessive fuel absorption. This can cause reduced fuel delivery, engine hesitation, and in worst cases, engine stalling while driving - creating a significant crash risk. This is a safety recall affecting multiple Toyota models.

Certain Highlanders are part of Toyota's large Denso low-pressure fuel pump recall (NHTSA 20V-012). The pump's resin impeller can absorb fuel, swell, and crack, causing the pump to seize. This leads to rough running, hard starting, and engine stalling — potentially at speed and without warning — creating a crash risk. The defect spans many Toyota/Lexus models; the Highlander was specifically named in the campaign.

Certain 2019-2020 gasoline RAV4 vehicles are included in NHTSA Recall 20V682 / Toyota campaign 20TA02 for a low-pressure fuel pump that may stop operating. The vehicle may display warning lights or messages, run roughly, fail to restart or stall while driving; a stall at higher speed can increase crash risk. Campaign eligibility is VIN-specific. The RAV4-inclusive recall is 20V682, not the initial 20V012 population cited by the old card, and the official RAV4 remedy materials do not support the prior Hybrid/A25A-FXS or diagnostic-code scope.

The Denso-built low-pressure (in-tank) fuel pump can fail without warning. The pump impeller was molded from a lower-density resin that absorbs fuel over time, swells, and binds against the pump housing, stopping the pump. This cuts fuel delivery and causes the engine to stall, often at speed. It was covered under NHTSA recall 20V-682 (Toyota 20TA02), an expansion of 20V-012, affecting roughly 2017-2020 Siennas alongside many other Toyota/Lexus models.

Certain later second-generation Tacomas were included in Toyota's large Denso low-pressure fuel pump recall. The impeller can deform, causing the pump to seize or lose output, which may lead to hard starting, rough running, stalling, or a complete no-start. Because the engine can stall while driving, this is a significant drivability and safety issue.

Tundras built with certain Denso low-pressure (in-tank) fuel pumps have a defectively designed plastic impeller that can absorb fuel, swell/deform, and strike the pump housing — causing the pump to seize. The result is hard starting, rough running, illuminated warning lights, and engine stalling, including potentially at speed, which is a crash risk. Toyota recalled millions of Toyota/Lexus vehicles (pump part numbers beginning 23220/23221) starting January 2020 and expanded it repeatedly; affected Tundra model years fall within the 2014-2020 range. A class-action settlement created a Customer Support Program extending coverage to 15 years from original sale for fuel-pump repairs.
