DTC P1141 Audi

Description

Engine started, battery voltage must be at least 11.5v, all electrical components must be off, the ground between the engine and the chassis must be well connected, the exhaust system must be properly sealed between the catalytic converter and the cylinder head, and the oxygen sensor heater for oxygen sensor before the catalytic converter must be properly functioning. Note: Vacuum in the intake system sucks in the leak detection spray with false air. Leak detection spray decreases ignition quality of the fuel mixture. This causes a drop in engine speed and changes the value produced by the Heated Oxygen Sensor. Note: Both Throttle Position (TP) sensor and Sender 2 for accelerator pedal position are located at the accelerator pedal and communicate the driver’s intentions to the ECM completely independently of each other. Both sensors are stored in one housing.
