P061B on Honda by model: symptoms, diagnosis and fix
Due to improper programming of the fuel injection electronic control unit (FI-ECU), sudden changes in throttle opening could turn on the check engine light and/or make the engine lose drive power, hesitate or stall. Supplier Denso told Honda the correction control logic for air flow rate and fuel injection volume was set improperly. Certain 2023-2025 Honda Pilot built September 13, 2022 to January 9, 2025 (also Acura MDX Type-S and TLX Type-S). Eligibility is by VIN.
How to Fix
Have a Honda dealer check the VIN for recall 25V031. The dealer will reprogram the FI-ECU with improved software, free of charge. Honda's dealer message specifies that no parts are needed for this recall. The control-module illustration does not recommend replacing hardware. Do not deliberately reproduce a power-loss or stall condition on public roads.

Frequently asked questions
What does P061B mean on a Honda?
P061B stands for "Internal Control Module Torque Calculation Performance." A generic OBD-II powertrain code. The powertrain control module continuously cross-checks its own calculated engine torque against the torque it commanded, and sets P061B when the two disagree by more than the allowed margin (on many applications roughly 50 Nm for longer than a second, typically at higher engine speeds) or when its internal self-test math does not return the expected result. Engine torque is used by the transmission, traction, and stability control systems, so most vehicles respond by cutting power and entering a reduced-power or limp mode. Expect a lit check engine light, poor acceleration, and possibly a throttle warning message. On Honda it is documented across 1 model: Pilot.
What are the most common causes of P061B?
The most common causes of P061B are: Failing mass air flow (MAF) sensor or intake air leak feeding the module bad airflow data, Accelerator pedal position (APP) or throttle position sensor fault, including dirty throttle body, Wiring, connector, or ground faults on the sensor circuits the torque model relies on, Restricted exhaust, failing turbocharger, or mechanical engine problem making real torque differ from expected, Transmission or hybrid/traction control module reporting a conflicting torque request, Low battery/charging system voltage causing module calculation faults, Internal PCM/ECM failure or corrupted software calibration (needs reflash or replacement). The specific cause varies by vehicle.
How much does it cost to fix P061B on a Honda?
Repair costs vary widely with the root cause and Honda model; each issue on this page carries its own estimate where one is published.
