Webb16 okt. 2015 · A good O2 sensor on a injection system should fluctuate from rich to lean about 1 per second. If the number of cross counts is lower than this, it tells you the O2 sensor is getting sluggish and needs to be replaced. Most lambda sensors will cycle from rich to lean in about 50 to 100 milliseconds, and from lean to rich in 75 to 150 … WebbDuring a Deceleration Fuel Shut-Off (DFSO) event, the Powertrain Control Module ( PCM) monitors the rear heated oxygen sensor (HO2S) signal to determine if the signal is stuck in range. The PCM expects the signal to exceed a calibrated rich or lean value within a calibrated amount of time.
