The P0341 code is a code indicating that the cam position sensor circuit is out of range or not performing properly. The P0404 code indicates the EGR is out of range or not performing properly.

Those codes seem rather odd to have together. If the cam sensor was bad I would expect some driveability issues or possibly even issues with getting the vehicle started. The EGR could cause some idle issues.

I just cant get past that those codes seem so unrelated, they are for two different systems. If you are not experiencing any driveablity issues, I would clear the codes with either a scan tool or just disconnect the battery for a few minutes. If they come back then yes, I would have it looked at. You could try replacing the Cam position sensor, and see if that helps, but the EGR is a bit more challenging and would be a more costly item to replace.

Hope this helps out.

    Those codes are common together if your internal engine has a lot of carbon built up inside, IE over 140,000 miles or so on the engine. I had the same problem with both codes at the same time. I used new sets of Copper plus Champion plugs and Autolite wires to clear the P0341 code, and cleaned the ignition coil terminals. The P0404 was dirty EGR, that I cleaned well, but the CEL keeps coming back, so I keep cleaning it, it is OK for a couple of weeks after cleaning , then the CEL come back , so I am not sure if I will replace it. That is the wife's car....

I own a 1998 Chevy Lumina, took it to Advance Auto. I know what one code is what does code P0341 mean and how can it be fixed?

Hi, Im AL the owner of Big As Auto Repair.

P0341 is a code for Camshaft Position Sensor Circuit. The first thing you need to do sense its a circuit code, is to change the Camshaft Position Sensor. I don't know what engine you have, but if its the 3.4 engine the sensor will be directly under the Power Steering Pump. Remove the pump and replace the sensor, clear the codes and hopefully the sensor does the fix. If not it could be in the wiring or engine controller. Hope this helps and please visit my auto-repair-website and give me a thumbs up.

    I have a 2002 saturn sl2 with a troublecode of p0341. the vehicle has 135000 on it. my step dad called auto zone and they told him twice that this code does not exist for this vehicle. So I would like to...

    Hello: First things first. If your car has a v/6 engine (3.0 liter) then yes code P0341 applies. The code relates to the camshaft position performance. The sensor is easy to replace, it is on the drivers side at the front of the engine (front of the valve cover) the sensor has one electrical connector and one bolt holds it on. If you have the v/6 engine then after replacing the sensor you will have to have a scan tool to clear the code.

    three things can trigger codes, an actual malfunction of the sensor, a loose timing belt (cam sensor) wiring problems like a defective sensor connector or wiring to the connector and a defective engine control computer, so just throwing part at the problem is very unwise, have GM dealer diagnose the codes and then based on the results you decide what you want to try and replace and what u think is above your skill level and better left to a professional technician.

    I have a 98 Ford Windstar and I have a code PO181 how to fix

    The P0181 code should not be showing on your particular vehicle. That code is for Natural gas vehicles. Your vehicle does not have a fuel temperature sensor. As for the other codes, the 7E5 and 1FE, those are strange also. You could possibly have a problem with your code reader. Try to use a different reader maybe at a auto parts store or a local shop. If those codes are still there, then you could have a problem with your pcm. For some reason it could think that the vehicle is a natural gas vehicle. Has the vehicle been struck by lightning or been jump started recently? Something could have caused a spike in the electrical system and caused it to go haywire.

    That code does not apply to this vehicle. However, sometimes a code reader will show a code incorrectly, especially if the code reader was a non-professional, home-user type unit. I have heard of people having a P0171 code show up as a P0181.

    There is a TSB (Technical Service Bulletin) for the P0171 code, and it details a pretty common problem that develops over time. I would suggest treating this as a P0171 code.
    Hope help.

    How do you reset the check engine light? 2003 chevy tahoe

    Check engine light came on for a reason. Could be one of a hundred reasons. My adivce would be to go to Advance Auto, O'Reilly's or any of the many Parts Stores and "borrow" a Code Reader. Easy to use and most places let you use it for FREE. The Code Reader will show what Code was set and what it MIGHT be. The Code Reader also resets the Codes and the Check Engine Light will go off.... until it senses something is wrong with your truck.

    Good Luck.
