Now I know for when it happens to me, or it happens to someone else here.

P0340: Camshaft Position (CMP) sensor, no signal P0498: Evaporate Emissions (EVAP) canister vent shut valve circuit, low voltage P0135: Upstream oxygen sensor, heater circuit malfunction P0141: Downstream oxygen sensor, heater circuit malfunction Quote from: "k24low20z" thanks man....i just noticed the alternator is bad..i took off the negative terminal and as soon as i take it off the car shuts off..i also noticed my windows having a hard time going up and some lights were not coming on.. Wait, how did you notice the alternator was "bad"? Unless you have it tested, there aren't any obvious tell tale signs that it's not operating to capacity to the untrained eye unless it's on fire. If you disconnect the negative battery terminal, you have disconnected the electrical system in addition to the battery. My guess is that the shop your car was in, never bothered to put your car on a battery tender or disconnected your battery while they were working on your car and just let the battery deep cycle (drain). Derrick is right. Let your battery charge to full capacity and clear the codes. If that doesn't work, have your battery load tested and then have your alternator tested. Title: Re: Car went crazy..

Post by: Mike on March 30, 2009, 08:53:06 AM Taking the terminal off while the car is running is an old school way to test an alternator however i'm not sure if it works on the 7th gen. I know it worked on some of the older domestics I've owned however i'm not sure how the electrical system in the 7th gens works.

If you have one of your OEM grounds disconnected, your car will not run. Alex, did you have your alternator tested? How many times have you deep cycled your battery? You may need a new battery too now that you've discharged it. Once a battery has been deep cycled, it will never get back to full capacity. Have your battery load tested. Title: Re: Car went crazy.. ABS-Battery-break lights are on.. Post by: ibcnunv on March 31, 2009, 08:11:42 AM Tim is on the money with his advice!!!! Our cars will turn off if the negative is taken off. Trust me; LOL I had the only problems because a loose negative cable.
Title: Re: Car went crazy.. ABS-Battery-break lights are on.. Post by: Skippy on April 04, 2009, 12:35:40 PM I don't know why your cars turn off when you disconnect the negative cable...it used to be widespread practice to change a battery while the vehicle was running until we were told it wasn't good for the vehicle.
I'm not sure if I'm not understanding something or what..but the job of the battery is to start the car and run the accessories when the engine is not running...the alternator powers the car while the engine is running and charges the battery. You can start one of our cars, disconnect and remove the battery, and drive the car while the battery is out... If the alternator is not running properly, the battery light will come on, and the vehicle will be running soley from battery power...which will not last long. I am almost positive that you can test our cars in the same way as the older cars...removing the negative battery terminal on a car where the alternator is not functioning should shut the vehicle down since you interrupt the circuit. Title: Re: Car went crazy.. ABS-Battery-break lights are on.. Post by: timot_one on April 04, 2009, 09:47:54 PM Only one way to find out. Time for someone with a healthy alternator to give it a try.
