Introduction
ECM offers three Lambda module kits: LambdaCANp, LambdaCANd, and LambdaCAN.
LambdaCANp is the latest Lambda module kit and can optionally be supplied with a P-comp
(pressure compensation) kit. The P-comp kit for LambdaCANp uses a pressure sensor with
an eight terminal connector. This eight terminal connector contains a memory chip with the
calibration of the pressure sensor (i.e. “plug-and-play”). LambdaCAN is the original kit
released and can also optionally be supplied with a P-comp kit. A LambdaCANd kit is
simply a LambdaCAN kit with the P-comp kit supplied as standard equipment. Both the
LambdaCAN and LambdaCANd kits use a pressure sensor with a four terminal connector.
The calibration numbers for this pressure sensor are written on a label attached to the sensor
harness and must be entered into the LambdaCAN or LambdaCANd before use (this is done
by ECM when a P-comp kit is delivered with the LambdaCAN or LambdaCANd). See
Appendix A for kit contents. The specifications for the kits are as follows:
