Hard shifting 1st an 2nd gear code P0010

[Lesfry86]

I have a 2007 Chevy Impala Lt 3.5 L reading code P0010 shifts hard thru first an second gears have a check engine lite on I have changed the camshaft positioning sensor also the plug to that sensor I have also changed the camshaft magnet stop shifting hard for a very short period of time after I chanced that now the lite is back on and the hard shifting persist please help can not keep just spending money also can not afford to pay shop prices. Thanks for reading and any help you may have! Happy 4TH

when the check engine light comes on the computer will substitute values for the sensor that it sees as a problem. That's to try and keep your car running so you don't get stuck out somewhere. But because it doesn't actually know what the value of that sensor is, or it wouldn't have to have the check engine light on, it doesn't want you to keep driving and perhaps weaken or damage something else, it goes into limp mode. That would be a reason the shifting pattern changes. Many times the cruise control will be turned off too. Some cars it will shut of the ac.

so after all the things that you have done to your car, is the check engine light still on now?

[Lesfry86]

Yes engine lite is still on

still the same code?

[Lesfry86]

Yes same code p0010 scanner says intake camshaft position (CMP) actuator solenoid control circuit bank 1 ECM has detected a fault in the camshaft actuator solenoid circuit bank 1 probable cause - open or short circuit condition bank 1 actuator solenoid circuit. Failed actuator solenoid bank 1 ECM fault is what the print out reads

what is the condition of your engine oil? Is it clean and are you using 5w30 or lighter? Can you scanner do a cam solenoid test? and have you checked the wiring to the solenoid?

also, what is the mileage on your car. is it still under the emissions warranty?

[Lesfry86]

Clean oil using 5w-30 no warranty and as far as a solenoid I have not been able to find one as I have see in pics online looks like a small shaft dealers says my car doesn't have it lost at this point

[Lesfry86]

100,xxx miles

If you have a scanner to scan for codes, does it have data stream capability? bi-directional tests? you're going to need to look at the data from the sensor and see if it has any correlation to the value the computer commands. Or if the wiring to the camshaft actuator solenoid

Just been going by what the local automotive store scanner is reading I am goin to check the wires that connect go magnet even thoe I just change it an didn't see any damage maybe on the bottem end of it not sure. After that I'm really out of ideas of what to check or try next?

if the scanner doesn't see the reading from the actuator solenoid look farther up in the wire harness. there could be damage up on top

you could try and unplug the actuator solenoid and check the wires with a dvom. Black wire should be your reference low (look for ground), brown wire is the cam actuator. put the black lead (-) from your dvom on the black wire and the red lead (+) from your dvom on the brown wire. (you could also put a 12v test light in between the two contacts on the harness and command the computer to raise the solenoid to 20%. you should see voltage on the dvom or see the test lighty turn on. If there is no voltage reading or no light on the test light check for continuity on those two wires at the ecm. Or, if you still have your old actuator plug it in and use the scanner to test the actuator solenoid. the pintle should move as you tell it to raise the pintle and back. also check the contact point in the cam actuator. (the part the solenoid pushes on in the car) can you move it?

Sorta lost by that information not that it's not good advice just don't understand it all making time today to check the wire from magnet and other harnesses for any bare wires do you think it's possible the new magnet bad befor I bought a new one I tried the magnet off my nephews 08 impala an as far as I could tell it fixed the problem no lite no hard shift now that I bought the new one it's just not working wondering if I should take part back to dealer an have them replace it? What do you think?
