VSS......and TCC? |
|
|
Hello,
I have a 1986 Oldsmobile Delta88 3.8L V6.
This winter i started getting the "Service engine soon" light. I took
it to be fixed and they retrieved a TPS code. The sensor was replaced
and adjusted.
But now i am getting another "Service engine soon" light with a code
24, which is a
Vehicle Speed Sensor (VSS) code. The light comes on the first time i
run the car in the
morning, when the wheels are not moving (parked). And when i start
moving the service
engine soon light turns off. It does not come back for the rest of the
day.
The car also has a high idle.
The car starts to do a surge condition when i start to brake for a red
light.
Recently i had a leak from the power steering lines that run over the
transmission. Could
this have caused this problem? Maybe got on the VSS or TCC contacts.
Any of you guys ever have this problem?
What you think it might be?
I already spend much this winter.

24 is the Speed Sensor Circuit problem code. It's not just about the
VSS, it concerns the whole electrical speed sensor circuit. You had the
TPS replaced and now there is a throttle problem. Possibly the TPS is
adjusted correctly and/or the ISC throttle switch is Open. Do you know
if the code is stored as a Hard code or an Intermittent one? Prior to
the first problem, was the speedometer working correctly?
This electrical problem has little/nothing to do with the transmission
converter clutch(TCC).

I am reading through the diagnostic aids and it says "disregard code 24 that
sets when drive wheels are not turning." Do you have any other codes coming
up?
It also says "a faulty or misadjusted park/neutral switch can result in a
false code 24." I would start by diagnosing that.

The Code 24 gets stored in the computer, it does not get erased unless
i disconnect the
battery. Would that make it a Hard code? As far as i could tell the
speedometer has
been working correctly always.
When the car starts to surge when i apply the brakes there is no
Service engine soon light
that comes on.
I also read that if that code 24 is set when the drive wheels are not
moving to disregard it.
but i am still getting the surging and high idle, so there is a problem
somewhere.
Thank you for replying so fast guys, i really appreciate it, i need all
the help i can get. |
