Errorp061a98 Top __top__ | Mercedesbenz

The Mercedes-Benz error code P061A98 specifically indicates a "Functional failure of the control module torque monitoring" where the component or system has reached an overtemperature state. Understanding Error P061A98

Root Causes of P061A98 on Mercedes-Benz

Mercedes-Benz engines rely on precise torque models for transmission shifting, stability control (ESP), and emission controls. When the actual torque deviates beyond a calibrated threshold (typically ±5-10%), the ECU triggers P061A98. mercedesbenz errorp061a98 top

Common Symptoms (Even Without Check Engine Light)

• Check Engine Light (CEL) illuminated – may be intermittent.
• Reduced engine power (Limp Mode / Emergency running mode).
• Hesitation when accelerating from a stop.
• Rough idle or occasional stalling.
• Cruise control and Speedtronic (speed limiter) may become unavailable.
• Transmission shifting feels harsh or delayed (due to torque interface with TCU).

Torque Mismatch: The code is stored when the PCM detects a significant difference between the calculated torque (based on sensors like Mass Air Flow) and the desired torque (requested by the driver). Check Engine Light (CEL) illuminated – may be

The P061A98 code is often triggered by a mismatch in data between the Mass Air Flow (MAF) sensor, which calculates actual torque, and the Accelerator Pedal Position (APP) sensor, which calculates desired torque. Potential causes include: Ошибка P061A98 - Mercedes-Benz E-Class - Drive2 Torque Mismatch: The code is stored when the

Q: Is this common on diesel Mercedes (OM654/OM656)?

A: Less common, but possible. On diesels, check DPF regeneration interruptions and EGR valve sticking.

W166 GLE / W251 R-Class (OM642 diesel)

• Inspect exhaust back pressure sensor (B60/8) for clogging – can skew torque model.
• Replace swirl flap motor if correlation errors also present.
