P1141 — Load Calculation Cross Check Range/Performance

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Volkswagen

About P1141

P1141 is a manufacturer-specific powertrain diagnostic trouble code recorded for Volkswagen vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1141 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

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.

P1141 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Engine Control Module (ECM) calculates engine load from more than one source and compares the results as a plausibility check. One load value is derived from the mass air flow sensor and another from the throttle angle and engine speed model. DTC P1141 is stored when these two load calculations disagree beyond the allowable tolerance, indicating that one of the inputs is reading incorrectly. The most frequent cause is a mass air flow sensor that under reports airflow, or unmetered air entering between the sensor and the throttle. When the code is active the driver may notice reduced power,...
