Speedometer does not work?

I took the car to a mechanic because the transmission was leaking badly and the timing belt needed changing. He fixed the trans by tightening some bolts, and replaced timing belt, water pump, spark plugs and several tubes and belts related to the system. After that, the car will only run properly in 2nd. In D3, D4 and 1 it revs but never shifts out of first and there is no pickup. I can't get it above 25 mph - I guess, since the speedometer stopped working after his "repairs". He seems mystified, but he's willing to keep working on it. Do I take it back? If so, what is the likely cause of this problem?

1990 accord with Auto 4sP trans, the S light blinks, and speedometer does not work. I replaced the VSS and problem still remains. I have a 17 code in the ECU and a 4 code in the TCM, I think they both point to the VSS, The Pin that protrudes into the VSS is turning when wheel is turning. Can someone point me to the wiring diagrams for the VSS? Unless you think I should try something else. Can Shifts and runs fine

Promechanic is right, though you should give the VSS a try, as it might fix it and it not very costly.

Figures, I'm in the 10%, replaced TCM and got same results, Can you recommend anything else or point me to wiring schematics? This problem started right after I replaced the coil in the distributor. Car was running terrible, after wires, plugs and cap did not solve the problem I replaced the coil, I noticed the cap seal must have been leaking and interior of cap seemed to have moisture. I replaced the coil anyway, but really think the problem was corroded contacts on the spade connectors. Probably just a coincidence, but within a day of getting it running again the trans problem started. Any suggestions would be appreciated.

Does anyone know if the VSS is an input to the ECU and the ECU can be the problem, Since VSS and TCM did not fix the problem and wiring is a low probability, I think I am running out of probable causes. Anyone seen ECU cause this problem?

I just bought this car and the speedometer doesn't work
Will it be the VSS and if that may be the problem where is the VSS located.
I'm looking to buy a Service manual but in the mean time I need to fix this problem.

Thank you

10/28/08 UPDATE. I checked yesterday and found the VSS and it looks new so it has been replaced already. So there is something else to be checked out. Any help will be appreciated.

Thank you

Had same issue, but has evolved into the s light doesn't come on at all now, and I have to use the key to unlock the transmission to put it into gear. I have to put in in low gear to start out as it is set to

Thank you for answering.

The car has automatic transmision. After I pulled the VSS sensor and looking at it of course it look new I put it back and now the speedometer is working? Not sure why. However the S light blinks intermittent and the transmision doesn't shift gears all the time it seems to be "stuck"on 2 you know the gears are 1/2/D3/D4 it doesn't change gears when I shift gears.
Thank you for your help.

Problem ended up being bad VSS, I purchased a Dorman -Part No 911-750 sensor, I returned it for new under warranty and problem fixed. Thanks for your help guys.

Thank you for your replay KHLow2008
Sunday Nov. 2 I checked the vehicle again and found that both of the coolant temp. Sensor are defective I'll get new ones at the dealer tomorrow. Checked with autoparts and they don't have them///I saw that the previous owern of this vehicle had changed the radiator and fan but I figure he hadn't repalced tohse sensors because they look old. Also will check the codes tomorrow because I didn't know how to do it before your replay
you guys have been very helpfull than you so much.

KHLow2008 I had chack thermal sensor in the past and looks like thsese type of sensors are not all the same. The sensors are good(found out after spending big bucks on new ones).
Automatic Transmision
my problem is the transmison will not upshift these happened when the S switch was pressed or activated now is erratic even after I disconected the battery cable to erase the codes(I also disconected the S switch is that OK?)I try checking for a code but the S light blinks inttermitent or it goes off and the transmision works ok.
I really can do without the S switch function
I like to know what is causing that I have removed and checked the Speed Ctrl. Solenoids(applied 12V and sounds like they activate(clicking sound)

Another question is it common on Honda cars to have poor conection between points I've been reading on a manual and it talks a lot about poor conections between connector wires.

I have removed and cleaned the conectors for the ECM and A/T control unit it did not make a diference.
Thank you for your help

KHLow2008 I did bridge the connector on Sunday but there were no codes. The S light came on yesterday and of course the transmission got "stuck" on second gear then I stop to pick up something to eat turn off the car and when I got back to drive it the light was off and the transmission worked fine. When I got home tried to get the codes but there is no codes not sure what is happening.
The TCM where is that located and how expensive is that part. Is there much dificulty to replace it.
I did removed the shifting solenois and applied 12VDC and they sounded like they worked(clicking sound)not sure if that means they are ok.
Your been very helpfull
Thank you

Ok KHLow2008 I jumped the conector and the S light came on. It looks like code one(light would blink and stay on and then the same)

The S light comes on inttermitenly and at that moment the transmision goes into 2nd gear
any help would be appreciated

Thank you.
