lots of codes... advice on where to start.

[Jaegze]

I have an 01 3.0i.

Driving yesterday had the cruise set at 70. First thing that happened was the car started to jerk a little bit. Then the trans error light came on. Then the car downshifted and ran high rpms. Then the battery light came on and the car was losing power. The car began to backfire and slow to a stop.

I ran the codes. p0102, p0015, p0141, p0444, p0161, p0492, p0491, and p0012.


I charged the battery and tried starting the car and it would not start. If I held the gas pedal to the floor it would start to kick but not start.

I am guessing this is either the battery or alternator due to the number of codes happening at once.

I recently replaced the alternator but I may have gotten a defective unit. I was also suggested to check the fuel pump. I was going to pull the alternator and battery and have them tested, but I am open to other suggestions as well.

Thanks in advance
