Web if the cats are defective the downstream o2 sensor detects o2 and a check engine light lights up. Front sensor stay consistently between.650 &.800.

O2 Sensor Readings At Idle - For example, during idle, the voltage readings should fluctuate between 0.1 and 0.9 volts as the engine cycles between rich and lean fuel mixtures. O2 sensors have heating elements in them that are activated by a relay. Determine which cylinder afr reading, front or rear, is bad. Open the main menu on your scanner, and select. Web how to test oxygen sensors. Web output of oxygen sensor readings:

Open the main menu on your scanner, and select. An open o2 circuit or a lack of an o2 sensor (dedicated) ground are signs of an o2 sensor trapped at a fixed bias voltage. Even the smallest exhaust leak can distort. The upstream o2 sensor electric potential can vary from 0.1 to 0.9 volts, where a reading of 0.1 volts indicates a lean mixture and 0.9 v indicates a rich fuel blend. If it is rock steady at 0.0 (corrections) in block 001 or 002 (forget which one), it means that they are disabled due to o2 failure.

Web One Front And One Rear Sensor Are Oscillating And The Other Front And Rear Are Rock Steady.

If your o2 sensor fails, it can trigger your vehicle’s check engine light to come on. At idle, the correct voltage reading from the o2 sensor helps maintain optimal fuel consumption, reduces emissions, and ensures the engine runs smoothly without stalling or running rough. Also, you may examine the state of the catalytic converter using live data from the o2 sensors. Web specifically, the p0172 system too rich code refers to bank 1 of the engine.
