vq statesman speedo fault!!!!

[paulf_01]

hey there peoples,
my partner and i just bought a 12/91 vq statesman 5L and have been told by the previous owner and when we test drove it that the speedo works every now and then.

i have rung holden and they say all it needs is a "Re-Calibration" but they want to charge some silly amount to just even look at it first.

can anyone help me the trip and other cluster functions work sometimes eg clicks over very slowly when i'm doing aroun 100kph on the highway.

could it be the transducer???

can anyone please help??

It could well be the speedo sender unit as in my old VP, which was about 70 bucks and was easy to change?


Speedo Sender - The electronic speedo sender on a VN commodore sends 10 ppr (pulses per revolution) to the speedo head for speed display. The speedo head then divides the input by 5 and sends a 2 ppr to the ECU for deceleration and idle control. The speedo senders can fail, which is evident when the speedo stops working, or when the speedo displays a flickering speed without the vehicle moving. VN's with automatic transmissions also rely on the speed signal for idle control during deceleration.

Vehicle Speed Sender unit - Part number 92034732
