P0232 on Honda
Fuel Pump Secondary Circuit - High
P0232 on Honda vehicles indicates fuel pump secondary circuit - high. Au7o has documented this code across 8 Honda models — most commonly on Accord, CR-V, Fit. This code means the engine computer has detected a high voltage signal in the fuel pump secondary (control) circuit, indicating the circuit that drives or monitors the fuel pump relay is reading higher than it should. The computer controls fuel pump power delivery through a relay and/or driver module, and a high reading suggests a short to voltage, a stuck relay, or a wiring fault in that control circuit. Depending on the fault, it can cause hard starting, stalling, or a no-start because fuel delivery is disrupted. The problem is typically electrical, in the relay, driver, or wiring, rather than the pump motor itself. Typical repair costs on Honda range from $300 to $1,200, depending on the specific model and root cause.
Common Causes of P0232
- •Faulty fuel pump relay (stuck or shorted)
- •Short to voltage in the fuel pump control wiring
- •Failed fuel pump driver module
- •Corroded or damaged connectors in the circuit
- •Faulty fuel pump (internal short)
- •Wiring chafed against the body or harness short
- •Faulty PCM/ECM (rare)
P0232 on Honda by Model
Honda Accord(1 issue)
- Denso Fuel Pump Impeller Failure - Safety Recall NHTSA 20V-3742018-2021
The 10th generation Accord (2018-2021) is affected by the largest Honda fuel pump recall in history, covering over 5.7 million vehicles. Denso fuel pump impellers were manufactured with improperly molded low-density material. The impellers deform over time under fuel exposure, expanding and interfering with the pump housing, causing the pump to slow or stop entirely. Symptoms appear gradually as difficulty starting, rough idle, and stalling, progressing to complete no-start. Engine stall at highway speeds presents a serious crash risk. Honda expanded the recall multiple times (20V-374, 20V-714, 23V-111) as the scope widened.
Honda CR-V(1 issue)
- Denso Fuel Pump Recall - NHTSA 20V-374 and 23V-1112018-2022
The 5th generation CR-V (2018-2022) is included in Honda's largest fuel pump recall affecting over 5.7 million vehicles. Denso-manufactured fuel pump impellers were made with improperly molded low-density material that swells and deforms under fuel exposure, interfering with the pump housing and causing the pump to slow or fail. Engine stalling at highway speeds has caused collisions. This is the same recall affecting the 2018-2022 Accord, Passport, Pilot, and other Honda models. Honda expanded the recall multiple times as the scope widened to cover additional production dates.
Honda Fit(1 issue)
- Fuel Pump Failure2007-2020
Fuel pump can fail prematurely across all generations, particularly in colder climates or with contaminated fuel. Difficulty starting, engine hesitation, loss of power, or no-start condition. Carter fuel pumps ($80-140) are consistently praised on FitFreak as best value - well-regarded aftermarket option. Airtex ($90-150) and Walbro ($120-160) are good quality alternatives. Replace fuel filter and use fuel system cleaner regularly for preventive maintenance.
Honda Insight(1 issue)
- Fuel Pump Failure (NHTSA Recall)2019-2022
The 2019-2022 Honda Insight (third generation) has been recalled for fuel pump failures. The fuel pump impeller was improperly molded (low density), causing it to deform over time and interfere with the fuel pump body, rendering it inoperative. Symptoms include engine stalling while driving (especially highway speeds), rough idle, difficulty starting, and complete loss of power. Honda issued recall covering many 2019-2021 models. Free repair at Honda dealers - fuel pump module replacement.
Honda Odyssey(1 issue)
- Fuel Pump Impeller Failure Causing Stalling2018-2020
Defective fuel pumps manufactured by Denso with improperly molded low-density impellers. Over time, impeller deforms and interferes with fuel pump body, rendering pump completely inoperative. Fuel pump can suddenly fail while driving, causing engine to stall without warning and preventing restart, significantly increasing crash risk.
Honda Passport(1 issue)
- Fuel Pump Failure (Multiple Recalls - NHTSA 21V-215, 23V-858)2019-2020
The 2019-2020 Honda Passport has been recalled multiple times for fuel pump failures. The fuel pump impeller was improperly molded (low density), causing it to deform over time and interfere with the fuel pump body, rendering it inoperative. Symptoms include engine stalling while driving (especially highway speeds), rough idle, difficulty starting, and complete loss of power. Honda issued recall 21V-215 in March 2021 (production dates Nov 2018-Jul 2019) and expanded it again with recall 23V-858 in December 2023 (through Oct 2019). Free repair at Honda dealers.
Honda Pilot(1 issue)
- Fuel Pump Impeller Failure Causing Stalling and No-Start2017-2020
Honda recalled 2,539,902 vehicles including 2017-2020 Pilot for fuel pump impeller defects. Improperly molded low-density impellers deform over time and interfere with fuel pump body, rendering pump inoperative. Causes difficulty starting, engine stalling while driving, or complete no-start. NHTSA campaign 23V-858. Parts availability issues delayed repairs until Fall 2024.
Honda Ridgeline(1 issue)
- Fuel Pump Failure Recall (NHTSA 23V-858)2017-2020
NHTSA recall 23V-858 affects 2.5+ million Honda and Acura vehicles including 2017-2020 Ridgelines. The Denso-branded fuel pump impeller was improperly molded with low-density material that deforms over time and interferes with the fuel pump body. Pump becomes inoperative, causing difficulty starting, engine stalling while driving (safety hazard), or complete no-start. This is an expansion of earlier recalls 20V-314 and 21V-215. Remedy parts were delayed causing extended wait times until Fall 2024.

Depending on the fault, it can cause hard starting, stalling, or a no-start because fuel delivery is disrupted. The problem is typically electrical, in the relay, driver, or wiring, rather than the pump motor itself. On Honda specifically, this code is documented across 8 models.
What causes P0232 on Honda vehicles?▼
