Using the Lambda Sensor Simulator
The Lambda Sensor Simulator outputs currents to simulate a lambda sensor and voltages to
simulate a pressure sensor. It is plugged into a LambdaCAN* module instead of the lambda
and pressure sensors. When plugged in, if the LambdaCAN* module is operating properly, it
will report the correct currents (i.e. lambdas) and voltages (i.e. pressures) output by the
simulator.
The simulator is a useful tool to check out a system where there is a problem and it is not
known if the sensor, cable, module, or data acquisition system receiving the CAN data from
the LambdaCAN* module is the cause of the problem. The simulator checks out everything
but the sensors, however once everything else checks out okay, the focus can be put on the
sensors. A properly operating LambdaCAN* module monitors lambda sensor condition and
can calibrate the lambda sensor. An external pressure source is required to check out the
pressure sensor.
Lambda Sensor Simulators can be returned to ECM on a schedul
e (1 year recommended) for
recalibration.
