After you replace these sensors. remove the battery cable for about 2 minutes then replace the battery cables. Start your car and let it idle with no accessories on. this should fix the problem. If not than you have another problem that should be diagnosed. I hope this wil;l help.

2000 Toyota Camry When the engine is cold and the car is started, the car engine usually vibrates ans shakes. I changed the plug and the problem stopped, but after a few weeks the problem started again. ...


Hello and welcome to FixYa!

Looks like that you have a bad O2 sensor. If the O2 sensor is faulty the car may shake and there's noticeable bad emission odor. I strongly suggest that you have it replaced. You can find this sensor on the exhaust manifold.

Do you have an erratic idle? If you do then the MAF sensor must be replaced as well. A bad idle can cause the vehicle to shake. Keep me posted regarding the progress.

Hope this helps and thank you for using FixYa! Have a good one!

Gas mileage is terrible,check engine light on,put on computer by friend said o2 sensor -i wasnt sure my friend new what he was doing so took to auto zone now they say the computer wont read


auto zone reader will sometimes not read codes. take it to your local garage and ask them to plug into it with an updated reader. i dont charge to read a code and i would hope they dont either. the o2 sensor could cause bad gas mileage. whens the last tune up done? check air filter. plugs? also check air in tires. low tires can cost fuel mileage as well. hope this helps

My check engine light won't go out. did have a misfire code corrected that with a set of plugs and wires. auto zone said scanner was showing a cataletic converter. I have good power. no starting problems....


If was you o2 sensor the code would say o2 sensor bad. Your catalytic convertor may not be heating up enough to make the emission computer happy and is sending a trouble code.

Sensors do not always fix engines,if he replaced the o2 sensors,they most likely where not the problem,o2 sensors give messages of lean,or rich mixture ,most of the time.Have you tried to clean the upper intake,tuned it up with spark plugs(from a good auto parts,not auto zone ) boots for the coils,and a good fuel injection cleaner,like LUCAS fuel treatment,and new fuel ,and air filter,,?You may need to have the fuel injectors cleaned,with a machine,replace,and check all vacuums,check the mass air flow sensor also,these can all have an effect on the engine emmissions.

96 Dodge Neon O2 sensor Ckt No Activity bank 1 sensor 1----how do I replace the sensor, will that correct a problem with the check engine light?


That would correct the problem, the O2 sensor is on the exhaust manifold or on the exhaust manifold down pipe. If you go to Auto Zone, they will have the O2 sensor you need and also the loaner tool you may need to remove the O2 sensor. Auto Zone also can give you the step by step instructions to replacing the O2 sensor in about 30 min. Once you located the O2 sensor, disconnect the wire harness and use the O2 sensor socket to remove the sensor from the exhaust. It's like removing a spark plug, to install the new O2 sensor is just to follow the same procedure in revers to the removal. Good luck.

Car keeps stopping


Sounds like you have a bad O2 sensor - typically what happens is the sensor will go into closed loop and stay there and once it cools down will open up and be able to start again - your car has two O2 sensors, it is best to replace them both - bet you notice your car getting crappy fuel mileage too. hopefully this helps you, as this is the most common problem - Also, clean your Mass Airflow Sensor, this is really easy to do and may help as well and should be the first thing you do before throwing a couple hundred dollars into new O2 sensors, use CRC mass airflow sensor cleaner available at auto zone or advance auto for about $10.00 a can, if you are not familiar with where it is located ask the guys at the auto parts store to show you - it takes like 15 minutes to do and requires only a t-20 torx bit - this part needs to be cleaned every 6000 miles.

O2 Sensors


Autozone oxygen sensors do not function properly in Toyota vehicles. Just had a Tacoma yesterday with the same issue. New sensors, runs poor, check engine light on. Toyota sensors fixed it right now.
