Once unscrewed, discard the old sensor and replace with the new unit. Confirm the fault code by selecting live data and comparing the value of the suspect faulty sensor to that of a known working sensor. The difference in the amount of oxygen between that present in the outside air, and that present in the exhaust promotes the flow of oxygen ions and produces voltage. These can all affect the oxygen sensors response characteristics, resulting in an extended response time or a shift in the sensor voltage curve and in the long run reduced sensor performance. These Remove passenger side front Use the factory wire retainers i Unless you are AWM then the whole thing is different the bosch catalog is wrong about the part # for the universal rear one.

OEM numbers are obviously different. In turn, the computer activates the check engine light and logs code P0430. Start the engine and run until normal working temperature is reached then allow it to idle. Whereas wide-band is 1V -5V, allowing for more detail when not at ideal operating conditions. To protect against the sensor becoming welded into its threading, Delphi sensors come with anti-seize compounds either pre-applied or included in the box. Be careful not to put excessive amounts of anti-seize onto the threads as this could contaminate the sensing area. The cookie is used to store the user consent for the cookies in the category "Other.

Because many late model vehicles have multiple oxygen sensors, be sure you correctly identify the bad sensor so you do not mistakenly replace the wrong one. A sensing element sits inside the sensor, encased in a steel housing. Are the sensors indeed the same functionally? This signal is then sent to the Electronic Control Module (ECM) and the mixture is adjusted accordingly. Most oxygen sensors come with a special electrically conductive anti-seize compound applied to the threads, so its merely a matter of threading the new sensor into the void left by the old one. Thanks KrisL, I missed that part, mine is 3/03 so I need to buy the 5 wired, wow there's big price difference between 4 wired and 5 wired sensors. The o2 (oxygen) sensor.
