Tuning chips or performance mods (like superchargers) that exceed factory torque parameters will log this code. Diagnostic and Repair Steps
Often, the ECM requires a simple software update or recalibration to correctly interpret torque data.
Diagnosing this specific sub-code (98) requires professional-grade scanners capable of reading Mercedes-specific live data. mercedesbenz errorp061a98 top
Corroded connectors, damaged wiring harnesses, or poor ground junctions can disrupt the signal between sensors and the control module.
In severe cases, the vehicle may cut out entirely or refuse to ignite. Tuning chips or performance mods (like superchargers) that
A persistent warning on the dashboard.
The vehicle will limit speed and RPMs significantly to protect internal components. The vehicle will limit speed and RPMs significantly
The (Internal Control Module Torque Performance) indicates a fault in the engine's torque monitoring system, often triggered when the Engine Control Module (ECM) detects a discrepancy between expected and measured torque. This "top" priority error often forces the vehicle into Limp Mode —restricting power to prevent severe engine or transmission damage. Common Symptoms
While P061A is a generic powertrain code, specific triggers are common in Mercedes models:
The Mass Air Flow (MAF) or Accelerator Pedal Position (APP) sensors provide critical data for torque calculation; if they fail, they trigger this code.
