Running Odd New Motor HELP ASAP

[aleromod101]

I just put in a new Jasper Rebuilt Engine car was running pretty well a little bit of some hesitation. So my check engine light came on popped up a P0336 which is crankshaft position sensor. There are 2 of thoses sensors on my 2002 3.4 alero. so I changed both out and cleared the code but now my car wont even worth nothing. Any help would be great. I thought about the case relearn thing but im clueless. PLEASE HELP!!!!

uhhh bummmp

ya case learn.

I replaced a CPS before under the pulleys but I never had a problem once code was reset. How did you reset yours? You might check the wire and connections on both. What do you mean your car is not working? Specific please.

I'm at the chevy place right now on my phone and these people don't have a freaken clue what I'm talking about

[jackal2000]

they are morons. all you should have to say is "it needs a case learn".

[aleromod101]

Well my car still runs like crap. The service engine light is still on and everytime i clear it it pops back up. I was at the chevy place and told them to do a case learn and i dont know about you but where my car goes i go. So I take a minute and then walk over there outside of the bay. And they start lifting my car. I said y are u lifting my car all im here is for a case learn and he was like well i did a diagnostic on it and it pulled up a P0336 code which is urs circuit relay or something. I was like man look that code is a cps and they both have been replaced and thats a new engine so thats y im here. When i said that he went right over the lift and dropped my car down and kicked the rails out and was cussing. He did something else. And walked off for about 5 minutes and now hes comming back with someone else. And they were doing something and was like it wont let me do a case learn case the service engine light stays on. blah blah and they keep saying circuit relay and i asked to see it on the scanner thing and they were like no no. You cant come into the bay. So i said pull it out and they were like no. And i said look unhook that shit from my car before i come in and do it. So they did. And then when they pulled my car into the little place where u suppose to pay that handed me a damn ticket to go pay for. I looked at them and was like u lost ur damn mind. And ripped that bitch in half and threw it down and got in my car and slowly drove off since thats all it will do. So any other ideas.

I like how you handled it...somewhat. Patience is a virtue...if you don't learn it now then you will have hard times in the future.

As far as the car goes; Try another dealer and let the shop know that you know whats up with it and you need a simple case learn. I wonder why you are having problems with this as the only thing my engine did when the CPS was out was turn on a light. Is the engine riding rough?

[aleromod101]

Well the thing is the were over there revving my car as high as it could go and trying to charge me for stuff that i didnt want. So kinda mean the way i came off but man like i have said in alot of post before i live in a small town and thats what its all about is making money and scamming people. But yeah the engine is running horrible takes me 10 seconds to get to 30 and then its like it wont shift for nothing. And the cat is new and tranny is great shape.




The car drives so bad right now that im not going to drive it anywhere and if i have to take it anywhere its getting towed well i have a car dolly.

What all did you disconnect when you switched out the CPSs. Have you checked the connections and wires yet?

[aleromod101]

only thing that was disconnected was the old sensors thats is

[AGT]

and its only throwing 1 code?

[aleromod101]

P0336 one code that code is for the cps

[AGT]

Have you changed out that new sensor? Where are both sensors...when mine went bad I only new of the one under the pulley...fixed luckily tho.

[aleromod101]

there are 2 cps and i changed them both

[jackal2000]

uhhh the case learn involves revving the engine dude. lemme see if i can find the exact steps...

[aleromod101]

well they were just holding it man like a minute at a time no clue i knew they revved it but idk they said they couldnt do the relearn cause of the light

[jackal2000]

and that is true. if there are other DTCs then you have to fix those FIRST. i found the steps but because of the site it is on i can not openly post them, sorry.

[aleromod101]

pm sent

[jackal2000]

how did you change the sensor? remove the crank pulley? maybe you damaged it...i dunno. there is a plethora of things it could be.

[aleromod101]

possible i dont know i thought the process of changing them both went quite easily and fast.
