We also use third-party cookies that help us analyze and understand how you use this website. If the test runs and the OBD II system detects too much of a drop off in converter efficiency, it will set a pending code. An O2 sensor can fail for many reasons. There shouldnt be a o2 sensor in your pre-cat. I tried a couple of them and got codes before I even started the car. The opinions expressed on this site are not necessarily those of the Club, who shall have no liability in respect of them or the accuracy of the content. But if the washcoat has been damaged or contaminated, the converter may not be able to trap enough oxygen causing a drop in efficiency. Allows measurement of a much wider air/fuel ratio for more detail when not at ideal operating.! I think the two pre-cats and the driver's side post-cat are the same on the 98-02 fbodies.

The downstream O2 sensor makes sure the catalytic converter is working. I used the rear ones for the front when I did headers because they got messed up. An oxygen sensor reads oxygen levels only; therefore, their voltage range is 0.10 0.90 volts. Every car made after 1996 has an O2 sensor upstream and downstream of each catalytic converter. Mendota Heights Police Scanner, The catalyst monitor is one of the most difficult monitors to set on OBD II vehicles. Inside are the valves and solenoids that control the pressures on the wheel. Even if it passes a tailpipe test, it may not be emissions legal as long as the MIL lamp remains lit. Low downstream O2 sensor voltageLack of power, Vehicle running rough, Exhaust odor, asymptomatic sometimesP0137 
As far as the working of both sensors is concerned, upstream is amongst the main inputs for fuel control, whereas the downstream is for emissions and On-board Diagnostics (OBD). Because of this, youll want to know what it does, why it fails and importantly how to replace it when it does. So any O2 sensor problems have to be dealt with before you can use the OBD II system to diagnose the converter. Oxygen Sensor LifeAn oxygen sensor should outlast the vehicle emissions warranty. Hi All, Just a quick question. We've seen converters that have been melted into a solid glob, creating a complete blockage of the exhaust.We've seen others that still pass some gas, but create enough restriction that backpressure chokes the engine and causes a noticeable loss of power and fuel economy. A lower voltage means there is too much oxygen in the mixture. O2 sensor 1 can also be called the upstream O2 sensor or bank 1 sensor 1. The sensor nose may be contaminated with shiny grey deposits. Archive -
Then a simple answer to this question is No. WebThe post-cat O2 sensors are identical to the pre-cat O2 sensors (same voltage outputs). But for best performance and fuel economy, just replace the Pre-cat O2 sensors at 100k miles. Home > Oxygen Sensors (O2 Sensors): How They Work & What They Do, Get expert-level DIY help from our certified mechanics Read and clear your check engine yourself View live OBD2 data to make DIY repairs easier Never miss an oil change with maintenance alerts. Knowing how the oxygen sensor operates and what makes up the exhaust gasses that flow past the sensors and through the catalytic converter can help in determining when to replace and prevent future problems. High upstream O2 sensor voltageVehicle running rough, Lower fuel economyP0132 1. The following are gasoline additives: octane enhancers, antioxidants, metal deactivators, ignition controllers, icing inhibitors, detergents and corrosion inhibitors.One of these ingredients is MBTE (methyl tertiary-butyl ether). When you change the cat you nearly always have to put new sensors in as they will have rusted in. Cookies may affect your browsing experience Bank 2 sensor 1 is the actual sensor and not wiring! During normal operation, the pressure from the master cylinder goes through the HCU unaltered. The sensors analog input to the controller is converted to a digital rich or lean command to drive a fuel trim software program. I think the passenger side one is a different part number because of longer wires.

Gasoline with a sulfur content of 1,000 parts per million (ppm) has been shown to cause accelerated degradation, resulting in the illumination of a service soon light. It contributes to the life of an oxygen sensor. The temperature shoots up and things really start cooking. Posts made and opinions expressed are those of the individual forum members
Some common identity differences between the both are the following: You may be thinking, Can I use a downstream oxygen sensor for upstream? So one of the components that should be recommended after an oxygen sensor replacement is the PCV valve. Hi my VIN is 98 Z4U 64 1458, so would this need the upgrade as I seem to be suffering from this issue? A converter that works well enough to keep emissions within limits at idle may literally run out of air at higher speeds allowing too much pollution to exit the tailpipe. In a Tech Assist bulletin, Lucas said: Many vehicles now feature a pre-cat lambda sensor and a post-cat lambda sensor. Oxygen sensors degrade over a period of time. Test how do I know if its my upstream or downstream O2 sensor be to. They also work with fuel. I'm going to change the exhaust on my 56 plate Zafira 1.8 petrol and before we got started today my cousin (who is helping me) suggested that I get a replacement sensor for the front pipe as when he's previously changed exhausts they have snapped due to rust. Two platinum (Pt) electrodes are placed on the ZrO2 to provide a connection for output voltage to a control module. Continue with Recommended Cookies. To put 1,000 ppm in perspective, if you have a thousand gallons of gasoline, it will have one gallon of sulfur. Downstream Sensor is in the Exhaust Pipe Post-Cat. If the Lambda has failed as a result of contamination it is likely that the sensor will have visual clues to the source. To determine these respective banks, you will have to view the picture of your vehicles firing order. Oxygen Sensors (O2 Sensors): How They Work & What They Do. america top doctors website It will read an accurate mixture, usually, but not necessarily, a voltage of 0.5 volts or higher. Use an OBD2 scanner to see the specific fault code that triggered the check engine light. Although pre + post cat sensors were different Renault part numbers ,and prices, both the Bosch aftermarket ones from Unipart had the same part number / price / cable length. 
Affecting PerformanceCan an oxygen sensor affect engine performance and fuel economy? Vehicle emissions may be a problem if converter efficiency is less than 90 to 94%. JavaScript is disabled.

When everything is working correctly, there should be a 14.7:1 oxygen to fuel ratio. Privacy Statement -
The current federal OBD II warranty period for an oxygen sensor is two years or 24,000 miles, May 25, 2014. 
There is no difference between the pre and post O2 sensors. We have good news! WebLorem ipsum dolor sit amet, consectetur adipis cing elit. Most oxygen sensors typically last 30,000 to 50,000 miles, or 3-5 years, with newer sensors lasting even longer with proper maintenance and upkeep. Other than the connector, is there a difference? The pre-cat (upstream sensors) are what the computer (aka ECM or PCM) uses to control the air / fuel ratio..these DO have an impact on fuel economy. A good O2 sensor should show a lot of switching activity with readings bouncing back and forth from 0.3 volts or less to 0.8 to There may be the odd I used the rear ones for the front when I did headers because they got messed up. Now reconnect the diagnostic tool and delete any related fault codes. This has affected the life of some newer oxygen sensors.
