Code Definition

P200E — Shift Solenoid B Circuit Malfunction

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Mercedes-Benz

About P200E

P200E is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Mercedes-Benz vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P200E is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P200E is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This DTC is set when the transmission control module (TCM) detects an electrical fault in the circuit controlling Shift Solenoid B. The solenoid is responsible for managing hydraulic pressure to engage specific gear ratios. A circuit malfunction is identified when the solenoid's current draw, resistance, or feedback is outside of expected parameters—suggesting a break, short, or control failure in the circuit.
