If you see a "check engine" or a "service engine soon" light in your instrument cluster; your car has stored a diagnostic trouble code. This means the computer system on your vehicle has detected a problem with the various systems it controls. Your car has many different sensors that monitor the various vehicle systems. If the trouble code light has been illuminated your vehicle enters into "limp mode" this means it is running on a predetermined program that causes poor mileage and increased emissions. An engine trouble code reader is an easy to use tool. All 1996 and newer vehicles utilize a "D" style plug-in connector that connects to the code reader. On most vehicles the connector is located at the driver's compartment. Once the code reader is plugged in you can retrieve trouble codes the engine computer has stored in its memory. These codes are the same codes the dealer and repair shops use to replace sensors and clear codes.

Position of oxygen sensors


all you have to do is follow the exhaust from the manifold back and you will come to the sensors. bank 1 O2 sensor is on the bank cylinder 1 is and bank 2 O2 sensor is located on the bank cylinder 2 is on. the first sensors you come across is sensor 1 then the next sensor you come across sensor 2 and so on. so you can have a sensor code like bank 1 sensor 2 meaning the sensor on bank one but the sensor is the 2nd sensor in the exhaust.

Check engine light was on. Connected scan tool, got data below and cleared faults. drove car 5 miles, check engine stayed off. p0300 random multiple misfire detected p0325 knock sensor 1 circuit...


If the check engine light stayed off then that means that those errors are not present at this time. It is not un common to have intermittent faults but I would not preced any further until the light comes back on. Then re-scan the code see which are to begin diagnostics.

2002 toyota rav 4 / code po420 whats wrong ?


You have a cat converter ie eficiency code. Most shops are willing to sell you a cat converter and make a quick buck. However you can save some major money if you can find out what is wrong. A cat converter doesn't just go bad by itself something causes it to fail. Most likely a bad oxygen sensor or a dirty mass air flow sensor. I would replace the oxygen sensor in front before I replace converter. Reset check engine light and see if light comes back on. If it stays off you just save about 600 dollars. Oxygen sensors cause cat converters to go bad. So fix the cause first, then if you have to replace converter.

Po507 could that be the idol air control


did you replace both 02 sensors? 02 sensors and camshaft position sensor do most of the engine timing. A bad vacuum hose will throw the timing off as well.

Code po157 what does it mean and how do i fix it?


P0157 Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2)

I would try replacing the Oxygen sensor, then clear the code.

The O2 sensor would be the after the catalytic converter ( sensor 2) on the exhaust pipe of the number 2 cylinder uses ( bank 2).

Try replacing the gas tank cover. Seriously. If that does not work, it could be the clutch sensor.

2002 kia optima wont pass emissions. check engine light was on, then turned off. how to reset computer


Reseting the cpu will clear the check engine code however it will not fix the problem that caused the check engine light to come on. The most common cause of failing emissions is the O2 Sensor. This sensor will trigger the check engine light when it is failing. The good news is that the Oxygen senser is pretty cheap and is mounted on your exhuast so it is fairly easy to replace yourself. I suggest replacing your O2 sensor the clear the computer by disconnecting the negative battery terminal and leave it disconnected for a few moments, hook up the negative again and it's all clear. Take your car back threw emmisions and you should be all set.

Hope this helps
