For the past couple of years, I've had every imagineable error light come up on the dash. They typically go off after 3 starts, which i've been told means the system reboots. There are currently none on, I'm certain that this is short lived.

I had a few events that led me to bring the car in and get a code scan. Here were the codes:

2-3-2 ; PO1550 ; PO1618

My understanding is that each of these is a speed sensor error, each from a different location - ABS, Engine, and Control Module. Is this accurate?

Here were the symptoms that led me to get the codes scanned:

ETS light on. (not unusual for the past 2 years). ABS and Brake lights come on simultaneously. (ABS light has come on the past 2 years, regularly). RPM's are effected very slightly, but I think just the tach, not the actual revs. Next, the Speedo goes to zero, and the odo and trip miles goto ----- across the board. Then, when coming from a stop, the engine revved but the tranny was maybe in the wrong gear - it almost seemed like an exaggerated version of winter mode. Then the tranny lurched into proper function (or gear). At this point, the speedo came back, the ABS and brake lights turned off, and the tranny failure light came on. Car drove fine. Check engine light also on throughout this period, never off. 2 days later, my wife called me and said that the car 'did something really loud and bad' when she shifted from park to reverse. Again, seems like maybe the speed sensor affected the tranny shifting? ???

I've had some other strange things the past few years:

1) Brakes feel funny. Wife has said she's had to jump on them twice at times. To me, this seems like ABS speed sensor. I've read about the problems on the ABS systems, and Victor Rocha's fix. But because of these other issues, and the codes that came up, I'm thinking this was caused by ABS speed sensors.

2) Sometimes, when I'm cruising, and I tap the brakes, the car revs very slightly before dropping off to idel rev. This happens without my foot on the gas. When trying to stop at high speeds, this is an uncomfortable thing.

The guy I brought it to wasn't the dealer. I don;t like my dealer, they are a long drive, and I knew the code scans would be accurate anyway. But he suggested I goto the dealer. I'd like to try and isolate the problem first. I need to replace the pads / rotors, and I figure that's a good time to check the wheel speed sensors. Any suggestions?

Thanks in advance.
