AEB 351/3 Lambda Probe Simulator 5V Straight - Oxygen Sensor Emulator for LPG Autogas Installations
Function and Application
The AEB 351/3 is an advanced lambda probe simulator specifically designed for vehicles with LPG installations or CNG systems. This 5V emulator with straight connector simulates the operation of an oxygen sensor when the engine runs on gas. The device prevents the engine management system from generating error codes and activating the Check Engine light due to deviations in exhaust gases during autogas use. The emulator is compatible with most LPG vehicles and ensures precise control of gas dosing.
Technical Specifications
The system operates with a power supply voltage of 10-14 VDC and has a current consumption of less than 75mA. The AEB 351/3 simulator is suitable for 5V lambda probes (also called titanium oxide sensors) that have a voltage range of 0.1V to 5V. The emulator produces analog signals sent to the ECU, allowing the engine management to operate normally while driving on LPG or CNG. The device can operate in a temperature range of -25°C to 80°C and must be protected from water, moisture and high temperatures.
Installation and Use
The lambda emulator is installed between the original lambda probe and the engine management system. Installation is simple and requires connecting several wires to the wiring of the oxygen sensor and the gas solenoid valve. With correct installation, the emulator intercepts the signal from the original lambda sensor and corrects it so that the petrol ECU does not register error codes when the vehicle runs on gas. The device is often used in combination with LPG conversion kits where manual gas adjustment is applied or when the catalyst has been removed.
Benefits
Using this lambda simulator offers important advantages: no error messages or warning lights, improved engine performance on LPG, accurate mixture control and reduced emissions of harmful substances. The emulator prevents the engine from entering emergency mode and maintains normal fuel consumption. This product is essential for professional LPG installers who convert vehicles to sustainable autogas systems and seek a reliable solution for lambda probe problems.
