2003 corsa c no speedo

[racin-snake]

hi guys ..anyone have a heads up on this fault ?
this corsa has no speedo needle movement at all when driving
it does move when you use op-com actuator
also it does get a speed output on live data when driven
but the speedo will move at stationary when revved ?
the code i got was p0500
any ideas ?
cheers ....

sounds like the clocks are fcuked, comm feature on this car, and many modern ones!

Remove the speedo head, behind it you will see a 'locator' remove this, feed to nearest dog you don't like, then use some smegma or smurf shit etc to 'glue' the plug into the dash.

Guess MIL not on, suggesting sender is ok.

yea i get comms and actuators on dash module
the sensor is sending a signal via live data
i aint scoped nowt yet
but i remember a post somewhere about dash cables being too short ? anyone ?

Common fault, connector for dash is fixed, and instrument pod has connector on back these push together when the dash is screwed in.
the Vauxhall fix is some double sided foam tape and contact grease, the tape is use to make the connector push further into the instruments.
I usually clean the connectors and use a couple of small cable ties between the connector and the support that it's mounted on.
I think it will be a bit more obvious when you remove the dash.
A quick test to see if this is the problem is to push the instruments quite hard in the middle and see if this cures the faults.

or like i said, throw the locator to the nearest dog you don't like.

OBD-II Check Engine Light Trouble Codes

In some cars work with abs sensors.
Sensor from left front -- abs module-- ECU, instruments.
You must see wire diagram of your car (diesel,gasoline)

"no speedo needle movement"

Run car and see if the total Km indicator run,if so maybe instrument panel damage.

this ones fixed
for future ref its the connection to the dah from loom
loosing contact some modifying and dielectric grease sorted this one ?
oh and a bit of help from a good guy

Are you refering to the acutual plug on the speedo head or another fault elsewhere?

[racin-snake]

loom multiplug to back of clocks ..the connector is shit and looses the connection

i have the same problem the speedo is not working on this corsa that came to me today the guys changed the speedo sensor/replaced clocks/reprogrammed it all is it would'nt start with the new clocks after all that the speedo is still not working even on the new clocks.... hmmm so if its not the connector at the back of the clocks as ive cleaned and re-inforced it a little to make sure there is a good connection it must be the plug you mention which one is it exactly?
thanks!

Can You get working speedo in actuator tests and is it reading vehicle speed in actual values on road test?

[JIMMYQ]

not working on the road either but not done any further tests as i was thinking the speed sensor may be a faulty unit before i read this thread

sorted just went out to the car to have a look at the plug mentioned above.
guy who's car it is did mention he replaced the radio in the car so as i was looking for loose connections i noticed some wires touching near the DAMN radio! sorted them out all is fine now weird but all good now thanks guys!

as you scream louder the car goes faster the more you scream, so the volume on the radio automataically goes louder when oyu scream and go faster.

blue/red by any chance
