But the specific “98” sub-code usually points to an —meaning a sensor is sending a baseline voltage that is wrong even when the engine is off.

: Sometimes accompanied by codes like P233822 (cylinder detonation), indicating the engine is pulling back torque to protect itself from damage. CarParts.com Symptoms to Watch For What is P061A Engine Code [Quick Guide]

Mercedes-Benz DTC Code: P061A98 Text: Internal Control Module Torque Calculation Performance – Component or function has a malfunction Status: Stored / Current Limp Mode: Yes (Reduced power, restricted RPM, possibly no ETC response)

Many independent mechanics see “torque performance” and assume the transmission is dead. In reality, less than 2% of P061A98 errors require a transmission replacement. The error is virtually always external (sensors, battery, software).

The Mercedes-Benz diagnostic trouble code stands for "Internal Control Module Torque Performance: Component or System Over-Temperature." In Mercedes-Benz vehicles—especially those powered by the M271 EVO and M274 turbocharged engines (found extensively in the W204 C-Class, W212 E-Class, and C250/E200 models)—this error is highly critical. It acts as a safety mechanism, indicating that the Engine Control Module (ECM/PCM) has detected a major discrepancy between calculated engine torque and actual powertrain limits, triggered directly by an extreme heat event.

A: Only to a repair shop. Limp mode is a protective measure. Driving long distances can overheat the torque converter.

Locate the main engine ground straps (usually connecting the engine block to the chassis) and ensure they are clean, tight, and free of corrosion. A poor ground is a frequent and often overlooked cause of electrical gremlins.

: The sub-fault code specific to Mercedes-Benz architecture denoting over-temperature or thermal overload within a monitored sub-system. But the specific “98” sub-code usually points to

Because this code relates to the engine management system, a wide range of symptoms can manifest. Here is what you might experience:

A noisy or intermittent CKP sensor causes the ECM to miscalculate engine speed acceleration, directly throwing off torque calculation. Fix: Replace the CKP sensor (Mercedes part # A 003 153 97 28).

: Use a dedicated sensor cleaner to remove oil or debris that might be skewing data [4, 6]. This link or copies made by others cannot be deleted
