Any help would be appreciated. Look for rust holes, missing gaskets, cracks or looseness. A severely plugged converter will result in the inability to increase rpm when under load. The unnecessarily rich mixture begins to foul the plugs, contaminate the oil, heats up the converter and drops the fuel economy. A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
Each exhaust system with a catalytic converter will have two sensors -- one between the engine and the converter and one after the converter. I asked him if he reset and he said no. If this can't be accomplished pull the plugs and check the condition. Repair any leaks and clear the code. Now don't ask yourself; What should you do with P2099 code? An oxygen sensor cannot know if an engine is running lean it can only know there is oxygen remaining in the exhaust. Next, they check the engine for exhaust leaks, as well as any signs of damages in the wirings of the O2 sensor.
Also check the engine oil for the smell of gasoline. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. Open the hood and install a battery charger. I changed the 02 sensor and all is fixed and it passed emissions. The code just means that the sensor signal was not within specifications. However, specific troubleshooting steps will vary depending on the vehicle. Disclaimer :This bulletin is supplied as technical information only and is not an authorization for repair.
Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another. The higher the oxygen content the leaner the fuel mixture, conversely the opposite is a rich mixture. Not all will be present simultaneously. A plugged converter will cause of host of driveability problems as well as set this code. I've heard that an exhaust leak from re-installing the O2 sensors might be causing this? Using a voltmeter, verify that the charging rate provides 13. If a code for the Mass Airflow sensor displays check its connector.
Fouled spark plugs are a likely result. So, if post cat and precat sensors are identical, the system knows the cats are toast. Have you burned through the entire tank of fuel that has been sitting in it? If the fail timer and accumulated mas flow exceed the fail thresholds, the test fails and the diagnostic stops running for that trip. The car drives just fine with no problems. An air leak or any of the above will cause an erroneous signal.
You should also check that the spark plug gap is set properly. Cross-reference any additional codes with the accompanying code sheet. The use of profile signatures to intentionally mislead or misdirect any member on this forum is not acceptable and may result in your account being suspended. I was out of town and it was a Sunday so I let an auto parts store pull it. A clogged converter will normally glow red. If it hangs low lean or high rich , the appropriate code is set for the sensor that's unresponsive or stuck. I am trying to figure out what simple solution might cause these codes to show up together.
If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Anyway mine had the update sticker. It will show the oxygen sensors in operation to easily recognize one that is malfunctioning. I got the P2098 about three months ago. When the sensors and converter are operating properly, the front sensor will have a higher count than the rear sensor indicating a functioning converter.
P2098 is the same for post cat 0xy sensor 2 bank 2. This way when used along with upstream O2 sensor makes the monitoring of the catalytic converters more efficient. It does this very quickly several times per second. Are there any other ideas as well? In operation the oxygen sensor will cycle once every second and send a voltage to the computer that ranges from 0. Jeeps and some Chrysler products seem to suffer from poor electrical connectors, so inspect them thoroughly. To check if the update has been completed, look next or behind the battery and there will be a serial number with the date of updating the computer. Spark plugs typically need to be replaced every season or 25 hours of use.
