Why would same diagnostic code up up twice for oxygen sensor that was changed and replaced already?
THERE IS MORE THAN ONE
There is a part of the sensor/computer operations that continually runs tests automatically and records values (that can differ), but if accumulated (the term I always heard) over a few runs indicate a problem then identifies and sends the error code. If you haven't reset it, just driving the car with a good 02 sensor through a few cycles...which are also determined by on off of key, until it overrides itself and sees a good reading and turns off light is all that is needed. Differs as does the computer determing good values and what tests to run when, but a handlful of on offs and 50 miles or so is standard to do it.
Is there a button to reset the service engine soon light I just replaced the oxygen heat sensor 1 of 1 bank as the diagnostic said was the problem but it still lights up?
Engine light on 1997 Toyota Camry EGR valve was replace the check engine light is still on diagnostic was done at two places the result of both was EGR how can i tune the engine light off?
What did the diagnostic code tell you before you replaced the EGR valve? You should not have replaced the EGR valve unless you have already run a diagnostic code otherwise you probably just wasted money. Oxygen sensors are a more common problem, especially since they routinely wear out. Also, map sensor, throttle position sensor, crankshaft position sensor... and a whole lot more, can cause a check engine light to come on. Don't guess; run a…
Check engine light on on 98 jeep grand Cherokee 4.0 liter IS ON .I REPLACED CONVERTER AND IS STILL ON.?
89 Buick Regal 2.8 trouble shifting getting to 65 miles pH and dies when it comes to a stop. replaced converter with a new one a year ago and it has burn up replaced mod. valve tran filter spark plugs?
Have you replaced the fuel filter? Have you run a computer diagnostic test? The fuel filter was replaced last year in march. have not ran diagnostic test yet. someone said it may be the oxygen sensor due to the catlettic converter going out twice in one year. still do not know why it is dying at light and not wanting to shift. am replacing O2 sensor today.
Can anybody tell me how to fix a p0135 trouble code on a 2002 explorer if i already changed the sensor?
If you replaced the failing oxygen sensor, you have to wait 3 drive cycles or 40 warmup cycles for it to automatically clear or you have to have the Check engine light code cleared if it's 96 and up. If not, disconnect the battery for 10 min. or more. Connect the battery and it should be off. If it is not then have it read again you may have changed the wrong one.
A tune up is always appropriate. Make certain that the ignition and injectors are working properly and that the oxygen sensor hasn't worn out. Check with the dealer to find out how often the oxygen sensor should be replaced. Also make sure that the air filter is clean. A tune-up should always include a diagnostic check using a code scanner.
the P1163 code refers to the Primary Oxygen Sensor in your car, which is found before your CAT, or catalytic converter. The code is "Primary HO2S (No. 1) Circuit Slow Response" I have the same code on my 98 Honda civic, but have already replaced the sensor, so i am in quite a situation. My check engine light WILL NOT GO OFF! but i hope i helped you if you havent replaced your oxygen sensor…
The magnesium is chemically changed and become magnesium oxide. The oxygen is also chemically changed from an element -oxygen gas, to a solid oxide. To confuse the answer slightly, they are also physically changed. The magnesium changes from a shiny, malleable lustrous metal to a white powdered oxide. The oxygen changes from a colorless gas to a solid oxide.
You took your silverado 01 6cyl to auto zone and they told you that the check engine was due to oxygen sensor. You changed it an it still does the same thing what could be wrong?
What could be wrong with 1995 cavalier if you changed oil spark plugs an wires air filter oxygen sensor and the map sensor if after all that it still has a rough idle an hesitation?
More than likely, its probably the oxygen sensor. The best way to determine why the light is on is to read the diagnostic code. There is a procedure to get the engine "Check" light to flash the diagnostic code; or you could take it to a dealer for them to read the code. By the way, the oxygen sensors should be replace every 70,000 miles.
In many cases we just add "oxide" to the name (like rust is iron oxide), though there are also oxalate, and a few others. Mostly it depends on how the oxygen combines with it, whether there are some hydrogens hanging off the ends, what the base chemical is, how long or involved the molecule was before the oxygen combined with it, how drastically the oxygen changed the physical properties, whether the new combination already has…
Just did this trouble code check to my 95 s-10. 12 code is the code showing your in diagnostic mode (flashes 12 three times). The code following this will be your problem's code. Mine was 13 (open wire at oxygen sensor). Replaced sensor and disconnected neg. batt cable to reset. I have list of codes if you need. Kevin
