is ur current speedometer driven by a cable? information on what meter n car u are using will be helpful.

check here, read the whole 1st page. ur car may not be LE, but it still applies to SVT and BT.

 

[ae101svt]

i'm driving a SEG and my speedometer is not driven by a cable from the gearbox.

 

[AE80TypeD]

then u should check the ECU or meter wiring. in the thread link i gave, member chinozie has encountered the same problem. read his reply and consult him if necessary.

AE80 bro...if the Km/H cable putus....the meter got show any light indicate??? or need to constant rpm between 2K-5K for 8 second then it will show out???

 

[AE80TypeD]

im not sure. are u talking about the electronic VSS wire? in chinozie's case, he encountered the exact same conditions stated in the diagnostic manual like u said.

in my experience last time using SVT, i was going full throttle on 4th gear coming to 6000RPM when the check engine light came on. the only indicator light that comes on on the meter when the error occurs is the check engine light. the weird part is chinozie experienced the "car-wont-go" loss power for a while syndrome while i only had the check engine light come on, no engine effect. all were solved once we made sure all the connections and wires are in/repaired to good shape.

just to share my last time experience regarding this:

1. speedometer (digital type) go crazy & give whatever reading below 3k rpm
2. engine check light on especially while climbing hilly road but i keep ignoring it
3. worst case: give a blast to a few capasitor in ECU that cause the engine almost dying condition+black smoke+drink a lot for fuel

the problem comes from the VSS (vehicle speed sensor) electronic type. mine is 3-wire type. it cant give constant signal to ECU & speedometer that result the car to run in safe-mode (according to Wong master) correct me if i wrong. when i push the car harder, the false signal cheat the ECU & i think ECU got fed-up so it warn me. after ignoring the warn, i still not repair it and finanally it cought the internal ECU parts... sob sob

solution:
1. i bought another ECU from master Wong which old capacitors replaced with a good spec type, tested and run well - tq sifu
2. replace the VSS with the good one. there are 2 type of VSS in SVT; 2 wire type and 3 wire type. if urs is 2 wire, ur are lucky, coz easy to find. if 3 wire, wish & pray for extra luck - very rare. my mech search all chopshop in klang and finally found only 1

from what my survey & reading, the VSS can be serviced to check the inner selenoid/wire. it might be dirty thus the selenoid cannot trigger proper pulse for detection.

i forgot already where the source of all this information but basically i do search on the net with this magic word (VSS, vehicle speed sensor)

that's all from my past experience. now the car goes to the new owner.... hahahahahaha...
