TO keep or not to keep

[SVX-FF]

I was just reading and saw this on the power light...

Power Indicator Light
The POWER Indicator Light is located in the combination meter. It is activated momentarily whenever the vehicle is started as part of the self check system. It turns “ON” when the TCU selects the POWER mode with the vehicle in the “D” range. It blinks a self diagnostic code whenever the TCU is programmed for self diagnosis.

The TCU monitors the throttle angle opening speed, i.e.,
how quickly the gas pedal is depressed. When a predeter-mined
rate is exceeded, the POWER mode is activated.

NOTE: THERE ARE A NUMBER OF PREDETERMINED RATES
BASED ON THE VEHICLE SPEED VS. THROTTLE ANGLE RELA-TIONSHIP.
THESE DETERMINE EASE OF ACCESS TO POWER
MODE. AS A GENERAL RULE, IT IS EASIER TO ACTIVATE THE
POWER MODE AT LOWER SPEEDS FROM A LIGHT THROTTLE
THAN IT IS AT HIGHER SPEEDS FROM A LIGHT THROTTLE.
Combination Meter

The POWER mode increases the upshift and downshift points. It is deactivated
by the vehicle speed and the throttle angle, i.e., if the speed is equal to or greater
than approximately 40 MPH with a light throttle, deactivation is immediate.
If the speed is less than approximately 40 MPH, a time lag of up to 3 seconds
will occur before resuming the normal shift pattern.

hope this helps too.

Hey thanks. I think I will try a lot of things once I get paid. I turned down autotchr because I was not going to keep the car and I really didnt want to be an inconvinience. I dont think a short amount of time is all it would take to help with the car. I get that much on here. In a short amount of time its still pretty much guess work. I think I am going to try the seafoam, then once I get paid I will try the o2 sensors (both of them) and then I am trying to get another TCU. I dont know if autotchr is certified but I already have a mechanic that can look at it. Plus I may not be the sharpest tool but I aint the dullest.


Dont mean to be pessimistic just depressed cuz of the car(s) and everything else in life that has been draggin me down. SO I try to once in a while.




The power mode stays on in my car whether I am going 80 or stopped. and it comes on whether I am givving it gas or letting it off or just staying at a constant speed.




Maybe I should have done this poll in the tech section. But I wasnt looking for help on the car just advice on wether to keep it or not. Anyways, thanks everyone fo all the help.


And it looks like the poll is almost completley favoring me to keep it.

.....and then people start voting to drive it off a cliff or repo it.

Also Tom I replaced TPS and voltage is good but the power light still comes on and stays on so obviously electrical something else maybe a short? I dunno[/QUOTE]

What did you do to set the TPS after you changed it? In my experience, you can't just swap out a swap out a TPS and be on your way. A TPS that is even the slightest bit off can cause the motor and tranny to do some wierd stuff. After I swapped out the one in my Toyota, it ran OK for a while and then started to get worse. So I took it to the dealer and they put it on their computer while they adjusted it. After 3 hours I get the car back and all is well. But again after a while, it started to sputter on decel, flare on shifts and just plain buck. So after 3 more hours at the dealer, they adjust it some more and the car runs better than it has in the six years I've had it. I guess my point is, setting up a TPS after replacement can be very difficult even for trained techs with all the scanners and computers at their disposal. Good luck.

Make sure you also reset the ECU by disconnecting the battery after TPS adjustment. Sometimes the adjustment won't take proper effect until the ECU learns the signal all over again
