O2 Sensor Fault Simulator

Overview Electrical Mechanical Functionality Pricing

Overview

The O2 Sensor Fault Simulator is a calibration tool used by OBDII calibrators to simulate several types of O2 Sensor faults. These faults include normal aging, ground offset, and silicone contamination. The Global Electronics Ltd. Simulator was designed with flexibility in mind. A micro-controller is used to make algorithm changes simple. An additional 3 digit thumbwheel switch can be added easily to accommodate additional functionality.

Functionality

The O2 simulator has 3 modes of operation.

• Bypass Mode: Simulator simply passes O2 signal through.
• Slope/Intercept Mode: The O2 signal can be attenuated from 0-100% and offset from -999 mv to +999 mv.
• Output signal = Slope + Offset Kup/Kdown Mode: This mode is used to alter the response time of the rising or falling edge of the input signal.
