Cadillac DTS Oxygen Sensor
The Oxygen Sensor is a significant component in Cadillac DTS cars as it helps in analysing the air/fuel combination based on the y presence of unburned oxygen in the exhausts. Depending on the oxygen concentration the voltage signal is produced, and the engine control computer adjusts the mixture for the premier performance with the lowest emissions. Self-diagnostic by memorizing steady-state rich and lean reference values and firing the sensor's zirconium dioxide sensing element coated in platinum at high temperatures, the sensor periodically cycles to sustain the catalytic converter effectiveness. Most Cadillac DTS automobiles contain more than one oxygen sensor; however, the most important one relays information to the computer as the upstream sensor. The oxygen sensor may degrade over time and this may result into enhanced emission of fuel and low efficiency and hence a need to be serviced or checked at times.
Each OEM Cadillac DTS Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Cadillac DTS Oxygen Sensor Parts Questions & Experts Answers
- Q: How to service an oxygen sensor?A: The oxygen sensors in the exhaust system are placed to monitor exhaust gas stream oxygen content. Oxygen sensors are three in number. The two upstream sensors are located on the front and rear exhaust manifolds. The downstream sensor is located behind the Catalytic Converter. With each of these, varying in between 100 millivolts and 900 millivolts is produced by reaction of the respective oxygen content in the exhaust. The ECM uses this output voltage to determine the ideal air/fuel mixture. Controlling fuel injectors pulse width, the ECM changes air-fuel mixture ratio. To enable the catalytic converter operate at maximum efficiency, an ideal mixture consists of 14.7 parts of air to one part of fuel that will minimize exhaust emissions using it for oxidation purposes during chemical reactions on its surface which can also provide enough heat for complete combustion of unburned elements in order not to produce such pollutants again as nitrogen oxides (NOx). It is important that oxygen sensor remains hot when functioning properly; moreover within this initial period known as warm-up stage ECM operates under open loop control strategy. Four things must be right for proper functioning of an O2 sensor; Electrically speaking Outside air provision Right operating temperatures Unleaded gasoline As you work on your oxygen sensor do keep these things in mind too!! The unit has a permanent connection with a pigtail and connector which must not be removed from it because it can only cause damage or prevent normal operation from taking place so do not even try it! Keep grease, dirt and other foreign materials away from both electrical connector and louvered end of this device. Solvents can never be used to clean any kind of a thing from them! Do not drop or otherwise mishandle Sensor. For proper operation, silicone boot should be properly installed so as not to melt down or distort while doing its job correctly. Remove battery negative cable.
