: Identifies an internal control module torque monitoring conflict.

The Mass Air Flow (MAF) or Accelerator Pedal Position (APP) sensors provide critical data for torque calculation; if they fail, they trigger this code.

: A heavily clogged filter can cause performance discrepancies that trigger torque monitoring codes. Electronic Control Units (ECU/PCM)

. This indicates the Powertrain Control Module (PCM) has detected a performance error where measured engine torque exceeds allowable limits or a specific component is overheating. CarParts.com Core Definition : Internal Control Module Torque Performance. : A sub-type byte indicating the component has reached an over-temperature condition. Kelley Blue Book Common Symptoms

Are you seeing any (like the Check Engine Light) or hearing the cooling fan running unusually loud?

Book a diagnostic with a specialist mechanic who has Mercedes XENTRY. Tell them to check the voltage delta on the speed sensors at "Top" idle. That 15-minute test will save you thousands.

Connect to Mercedes XENTRY or a dealer network. Many P061A98 complaints are resolved by (as of 2023-2024 TSBs).

A stuck-closed thermostat prevents coolant from flowing to the radiator, causing rapid overheating. In a case study of a Mercedes E200, the thermostat had actually burst open, leading to a complete loss of coolant after a previous repair, which then triggered the P061A98 code.
