My TCS & ABS lights began coming on and eventually stayed on. My local dealer diagnosed malfunctioning sensors and quoted a $200@ parts price. It also quoted $1,000 for a 105,000 mile tune up to my 2000 Acura 3.2TL. That was months ago (somewhere around June 2006). That was enough to scare me off. I have since gotten an on-line (Edmunds) estimate that a 105,000 tune up for my car should run ~$400 in my zip code area.

On August 7th my wife woke me to close the car windows because a thunderstorm was coming. I must not have been fully awake because I left the keys in the ignition and the ignition in the ON position.
The next day I found what I had done. The battery was near dead and I had to jump start the car. I placed my Prestone Jump It (A heavy portable battery jump starter) on the engine and got my car started.
Then I discovered that my Check Engine light had joined the TCS and ABS in staying on continuously. I also took note that the Jump It may have rested on the DENSO "Sensor.Map". I tried resetting the sensors per owner's manual instructions to no avail. Jiggling the "Sensor.Map" connection also failed to accomplish anything.

I went to AutoZone where they ran a diagnostic that resulted in finding the following faults:

P1607 - ECM/PCM Circuit Failure
Probable Cause - Failed ECM

P 1676 - FPTDR Signal Line Failure - Traction control system
Probable Causes
1. Open or short circuit condition
2. Poor electrical connection
3. Failed ABS/TCS control unit
and P1768 - Pressure control solenoid valve A circuit fault

Probable Causes
1. Low transmission fluid level
2. Open or short circuit condition
3. Poor connection
4. Failed PCS solenoid A

Since my local dealership has scared me off, I am hesitant to trust my ignorance to it. Any assistance in reducing my ignorance and/or correcting my problems will be greatly appreciated.

Have a load test done on your electrical system. My idiot lights came on and when I pulled the car over, it went dead. Had the battery jumped, but found that the alternator was fried. So $300 for a rebuilt alternator and new battery, all is well !

1000 is about the norm for the 105 service. Not 400. the 105 service includes the timing belt and waterpump. Pain/takes time to change.

Now for your problem. Pull the clock backup fuse for a min or so (on the passenger side dash fuse panel) and see what codes come back. Also fix the known sensor for the TCS/ABS light.

You have lost me. How would I find the "known sensor"? How would I fix it? The dealership was not specific when it told me that I had faulty sensor(s).

The Edmonds - http://www.edmunds.com/maintenance/maintenance.do -Total Estimated Cost (excluding tax)* $ 398.91 [Year: 2000; Vehicle make: Acura; Vehicle Model: TL; Vehicle Trim: 4 Dr 3.2 Sedan; Vehicle Engine: 6 Cyl 3.2 Liter; Vehicle Transmission: Automatic; Current Milage: 105,000; Zip Code: 12590] called only for checking the water pump but even replacing it should not account for a $600 difference. If $1000 is about norm, why is Edmonds so far off the mark?
The* refers to the disclaimer which mentions that services beyond those recommended by Acura may be preformed. I am also well aware that replacing a water pump on cars is no longer the DIY job that it was on cars built back when.

It is advisable to replace it during the timing belt work because it's accessible then- not much extra labor to just replace it at that time. Also that est. may not have included the tensionsers, etc. that ought to be done at the same time.

Thats 7 years or 105,000 miles whichever occurs first, many people go longer than that, but at your own risk of timing belt failure or water pump leaking.
Then you have between a major and massive problem

I can see 400-600 in LABOR for the job at least!
a PROPER 105 SERVICE-if you look in the owner book, not edmunds-is over 6 hours labor, not including the plugs and extras it will need-- like hoses and tensioners and new belts and filters. 1200 PLU$$$ is about right

Use a private shop and do what you can at home to save big
includes a full tune up with spark plugs and the other things mentioned above

Get your info from acurazine and the owner book, not edminds, then come here to argue the differance.
At least we drive a TL and work on it- so we have real world times and cost and most things you can do to the car

Dealer should have written on work order which wheel speed sensor was bad.
Then you buy 1 and have a buddy install for you- about 50 bucks for the part
That should fix the TCS lights

You would have to be an idiot to remove all the stuff for the timing belt and not replace the all important water pump while you are there.
Its lasted this long- be grateful- last another 100k? NOT likely
So you or the next guy pay labor to do a job twice- that makes no sense, unless you are the service writer!!

Haven't replaced one of those- that's not hard is it?

Depending on which ones, not hard unplug and remove (unbolt if a its bolted into place). Reverse directions for install.
