How is the O2 sensor connected to the ECM?
https://play.google.com/store/apps/de… The O2 or Oxygen sensor is in charge of measuring the content of the exhaust. Learn about the O2 sensor electrical connection and how it relates to the ECM and signal output. Presented here to help you understand the O2 sensor from an electronics and wiring diagram point of view.
What should the voltage be on the O2 sensor?
The sensor voltage should cycle or fluctuate within the 100 mV-900 mV (0.10 to 0.90V) range. Hence, This means the sensor is operating properly. If the (O2) sensor only produces a low or high voltage signal. So, either you have an engine performance issue or the (O2) sensor stopped working.
Why is the O2 sensor signal switching rich lean rich lean?
The fact that the O2 sensor signal is switching rich-lean-rich-lean also reveals that the ECM is controlling the injector pulsation and therefore that the system is in close loop mode.
What are the colors of an O2 sensor wire?
O2 sensor wire colors MANUFACTURER SENSOR MFG 1 WIRE 2 WIRE 3 WIRE General Motors DELPHI VIOLET VIOLET VIOLET PINK BROWN BROWN
How to connect pre cat sensor to post cat sensor?

Where is the pre cat and post cat lambda sensor?
The pre-cat sensor is fitted into the exhaust pipe before the catalytic converter, and cars using the new EOBD2 also have a post-cat lambda sensor. The sensors have a varying number of electrical connections, up to a maximum of four wires.
