1997 Camaro RS, codes P0302, P0336, P0441

Hello,

I have a 1997 camaro rs. The service eng. light came on so i took it to AutoZone and came up with these codes, P0302, P0336, P0441. I know what the codes mean but i dont know how to fix it. The people at AutoZone said that most likely one of these codes was causing the other two.

What code would most likely be the cause of my problems? I am guessing its either the P0336 or the P0441 (hell maybe both i guess). I dont know if this helps but the car drives the same. i cant feel anything different in the way it drives or feels. Does anyone know how to fix these problems?

Thanks for any help you can give.

So you think the evap dtc is causing the misfire!

Im not sure. thats why i was asking on here. At AutoZone they said that its either the P0336 (Crankshaft Position Sensor) or the P0441 (Evap Emission Control Purge flow Fault). And that most likely one of those is casuing the missfire. Is that possible? And which one is more likely to be the main casuse. Because like i said they think one is casuing all of the codes. Could one me casuing all the codes or do you think more then one this is wrong. And like i said i dont feel it misfire.

Also they gave me the price of a new Crankshaft Sensor, said it was easy to do myself. Is it? Also they told me that i could not buy a Evap Canister which could me the cause (i would have to go to a dealer, which i realy dont have the money to do. And i like to do work on my car myself), but their not sure. They said that it could need a new canister purge value, which i could buy their. Is that easy to replace and could that fix my problem or are they just jurking my chain?

Sorry for all the question but i have never had codes P0336 and P0441 before so i am a little in the dark.

I could see the crank sensor causing a misfire but not as likely a purge problem. I think you've got more then 1 problem. The crank sensor may require removing the balancer to change it so depending on your tool kit and expertise can dtermine how easy it is. If you've never done one A camaro would probably not be most peoples first choice to learn on. The critical thing on some crank sensor installs is getting the airgap correct and not damaging the reluctor wheel when the balancer is being removed and installed. The po441 fault could be the cannister, the valve or a gas cap, hose leak etc! It can be several different issues. If you choose to buy a crank sensor I'd recommend the dealer part, same for the purge solenoid. If the misfire dtc remains after the crank sensor and purge repair then I'd look into a spark plug or ignition problem assuming the engine and fuel system are sound! Is this a V8 or V6?

Its a V6. I had a problem with the misfire before, when that happen i ended up replacing all the spark plugs and wires, then i found out that it was just the coil, guess i should of checked first. After that i had no problem. So i am pretty sure that if i replace the other ones then it will go away.

I have work on this camaro before and yes its a pain in the ass, you should of seen me just trying to replace the starter. the part they told me to buy, they said that it just plugs in and the hardest part was finding it. But like i said i have never replaced a crank sensor before. My father in law is pretty good with cars so he would more then likely know how to do it, if i ran into something i couldnt do. They also said that the problem could be just a blocked hose, you think that could casuse the dtc code?

I know that this is a bad question, but is their any way to find out what is casuing the P0441. I have replaced the gas cap before, so i think it could be less likely that.

By the way thank you for all the help you have been giving me!

As far as do it yourself for the evap code check that there is no damaged missing vaccum lines in the evap circuit, check the solenoids and valves for proper resistance but without a smoke machine or a scan tool and a wiring diagram that can manipulate the valves and such in the system it can be tedious! It is more then likely the valve itself. They're pretty common failures on lots of GMs! A V6 camaro is probably not the bad to remove the balancer in and the 3.8s are known to have crank sensor issues! The misfire dtc should it remain maybe an injector or ign module/coil pack problem but start with the crank sensor and the purge solenoid and see what remains. Keep us postted on your progress!

Thanks for your help Jeff. I am goin to go ahead and replace the crank sensor. I have heard form a few people now that the 3.8s have problems with the crank sensor, i guess with how many miles this thing is pushing (for being a sport car) that its just luck that i havent had problems with it in the past.

Also about the evap code. After your last post about things that could casuse this code i went out to check a few things, and the gas cap was not on all the way I guess it could still be something different but after i replace the crank sensor this weekend i will drive it and see if the dtc code goes away. If it doesnt then i will move on to replace the valve (hope it doesnt come down to that)

Also do you think its safe to drive the car? I dont need to take if far but i dont have much room to work at my place so i am taking over to my father in laws house. I am not sure how bad it is to drive with a bad crank sensor and i dont want to casuse anymore probelms.

Thanks aging and i will keep you updated on how things are going and if i can get those codes to come off. you da man jeff, you really know your way around a car!

yeah it's probably safe to drive it your relatives. If it's not failling to start then you're probably on to the problem soon enough. keep us updated of your progress!
