Corroded connectors, damaged wiring harnesses, or poor ground junctions can disrupt the signal between sensors and the control module.

Often, the ECM requires a simple software update or recalibration to correctly interpret torque data. Often, the ECM requires a simple software update

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

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 This "top" priority error often forces the vehicle

While P061A is a generic powertrain code, specific triggers are common in Mercedes models:

Diagnosing this specific sub-code (98) requires professional-grade scanners capable of reading Mercedes-specific live data.
