P0087 on Lexus
Fuel Rail/System Pressure - Too Low
P0087 on Lexus vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 4 Lexus models — most commonly on ES, GS, IS. This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode.
Common Causes of P0087
- •Clogged or dirty fuel filter
- •Weak or failing fuel pump (lift pump or high-pressure pump)
- •Faulty fuel pressure regulator or control valve
- •Restricted or leaking fuel lines
- •Faulty fuel pressure sensor
- •Air in the fuel system or running low on fuel
- •Worn high-pressure pump (direct injection/diesel)
P0087 on Lexus by Model
Lexus ES(1 issue)
- XZ10 ES: Denso Low-Pressure Fuel Pump Impeller Swells and Stalls the Engine2019-2020
The 2019 ES 350 (and other 2019 Lexus models) were recalled under NHTSA campaign 20V012 for a Denso-supplied low-pressure in-tank fuel pump. The impeller was molded from a lower-density resin that absorbs fuel, swells, deforms, and binds against the pump housing. The result is a rough-running engine, a no-start, or - the safety issue - a stall at speed with no warning. Toyota's January 2020 recall covered roughly 131,000 vehicles initially and has been amended and expanded repeatedly since, with the most recent amendment in January 2025. Related class-action filings alleged that some 2018-2019 vehicles with the same pump were left out of the original scope.
Lexus GS(1 issue)
- Denso Low-Pressure Fuel Pump Impeller Swells and Stops the Pump (Recalls 20V012 / 20V682 / 26V222)2013-2020
The L10 generation GS uses a Denso in-tank low-pressure fuel pump whose impeller was molded from a resin with too little density. The impeller absorbs fuel, swells, and interferes with the surrounding pump body until the pump stops turning. The failure shows first as a rough-running engine and warning lights, then as a stall - and at highway speed a stall raises crash risk. Recovery is often impossible: the car will not restart. This is the same Denso pump defect that grew into one of the largest Toyota recall campaigns ever, and the GS was pulled in over several expansions: 20V012000 covered 2013-2015 GS 350 and 2018-2019 GS 300, 20V682000 covered 2017 GS 200t / 2017-2020 GS 350 / 2019 GS 300, and a 2026 expansion (26V222000) reached 2015-2022 Lexus vehicles including 2016-2020 GS. It is an L10-only issue; the S160 and S190 cars use different pump hardware.
Lexus IS(1 issue)
- Fuel Pump Impeller Failure (Recall)2018-2020
The low-pressure fuel pump impeller can deform due to excessive fuel absorption, causing the fuel pump to become inoperative. This results in engine stalling while driving or inability to start, creating a serious safety hazard. Toyota/Lexus issued a massive recall (20V-863) affecting over 1.8 million vehicles across multiple models.
Lexus NX(1 issue)
- Low-Pressure Fuel Pump Failure Causing Engine Stall (Recall 25V028000)2019
The low-pressure fuel pump inside the fuel tank can fail, cutting fuel supply and stalling the engine — potentially at speed and in traffic. This is the same Denso low-density impeller family of failures that ran across a very large number of Toyota and Lexus products, in which the impeller absorbs fuel, swells, and binds in the pump housing. NHTSA campaign 25V028000 covers 2019 Lexus NX300 alongside the 2018 Camry and 2019 RX350L. Owner notification letters were mailed March 12, 2025, and the campaign numbers are 25LA01 for Lexus and 25TA01 for Toyota. The remedy is replacement of the fuel pump assembly.

What does P0087 mean on Lexus?▼
P0087 stands for "Fuel Rail/System Pressure - Too Low." This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. On Lexus specifically, this code is documented across 4 models.
