You have a picture or site where ilustrate this valve circuit? All are located in the air induction plenum. The throttle valve is closed. Thank you, Diana Mitsibushi Galant 1996, 80,000 miles - August 2008 Answer: Hi Diana. How can I reset the computer to see if the problem was solved. You might continue by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data. The most common cause of this code is that the sensor becomes contaminated and is slow to respond to the changes to the exhaust gases lazy sensor. Even then extremely poor gas mileage.
The other problem is that the sensor heater is faulty. In the long run it may be easier and cheaper to just take the car to a trusted, qualified technician if you're not mechanically inclined. I had 2 codes, a P0403 and a P0431. Error code says bank 2 sensor 2. I tryed disconnecting the battery and the light never shut off. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port.
Or you could buy a repair manual book. If this can't be accomplished pull the plugs and check the condition. Although I don't have a definite answer for you, from other sources it appears to be the driver's side. The car is Montero 1996. Replace one or all of the 02 Sensors? Using a scanner can check all four of the O2 sensors for proper operation so you can be sure to change the correct one. Question: The code in my car is P0443 Evaporative Emission Control System Purge Control Valve Circuit.
Question, is bank two on the drivers side? I have a 2000 Montero Sport. Thanks - Lee, September 2008 Answer: Hi Lee. Will the Check light cause me to fail. Question: I have a 2001 Mitsubishi Galant V6 and my check engine light came on. The software returned a single error code P0431 which after a Google search I found to be linked to Warm Up Catalyst Efficiency Below Threshold Bank 2.
Disconnecting the battery is not the recommended way to clear the trouble codes as it may cause other issues. Could be a many things. I had the problem diagnosed and fixed what I think is the problem. I would recommend you go to AutoZone and get them to read the trouble code for you which is free and then do a Google search on the code or post back here. You may have two of them in your system. I reset the light and after a few days it turned orange again. As well, you should also check out.
If the engine runs perfect then it may be one bad O2 Sensor but it may not. Also all of those codes have to do with ciruit malfunction. P0401 Exhaust Gas Recirculation Flow Insufficient Detected Check Conditions At least 20 seconds have passed since the last monitor was complete. Feb 25, 2015 Well for starters I would re-check the codes and verify that all of the same codees returned. It means your O2 sensors are being effected by a problem upstream.
Because you have replaced the components then your situation is located in the wiring or possibly even the vehicles computer. The car runs the same but is now getting much better mileage. These four sensors are right at the throttle body. A quick call to your dealer can confirm that. Look for damage to the tank indicating impact that may have damaged the fuel pump or sender.
I was driving when the Service Engine Soon light reared its ugly face. Is there only one cat converter on the vehicle and two sensors behind it? After replacing the 4th and final O2 sensor I thought all was well but 2 weeks later the same code reared its ugly head. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. The car seems to run just fine. I know sensor 2 is behind the cat converter. The mass air flow sensor and the manifold absolute pressure sensor are one in the same.
The check engine light is on for a reason, it's telling you the car is in need of attention. I've seen times where a cheaper aftermarket sensor failed prematurely. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 on this site the. I must preface the actual question by saying I have no intention to do the work myself. Since the P0403 code description specifies the circuit, it's not talking about the valve. I checked it with a code reader and it came back as P0431. Question: My light has been on for a year.
