People on the Jaguar Forums say a poor ground (earth ) connection can cause this symptom. A block of relays control the instrument panel including the speedometer. a corroded or intermittently connected ground. could be it. cold corroded connector would conduct better than a hot one.

Or the relay could be defective.

You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

If the speedometer and odometer are not working the problem is usually lack of signal from the transmission speed sensor.
But if the cruise control works and the speedometer does not, my guess would be a problem inside the cluster.

that is: Intermittent Loss of CMP or CKP which means intermittent loss of crank sensor or cam sensor signal most likely something a dealer or tech needs to repair.
Hope that helps, if this was accurate please give a thumbs up so others know too

Check that the fuse for the turn signal is not loose. Sometime a firm push inside is needed. If that doesn't work replace the fuse. If it is still loose then take a narrow pice of wire and insert it in with the fuse to keep if from being loose.

The problem could also be at your turn signal stalk. Turn of the turn signal and then move the turn signal stalk in different directions and hold it. You are trying to see where the intermittent problem goes away. If it doesn't , then the stalk is fine.

hi, sounds like the vehicle speed sensor mounted on the transmission is going bad or loosing signal. generally, honda speedometers work for life, i've only ever replaced one. now, this is a split year so it may have just a cable going to the transmission instead of an electronic sensor. if the cable is loose, this may also cause this issue. you should probably have a professional shop take a look as the speedometer cable/sensor is very buried in the back of the engine compartment under the air intake hose and behind the starter. also, if there is a check engine light on when the speedo stops working, this should be an easy diagnostic for a technician to do, it would likely be the speed sensor causing this engine light.

its probly a bad alternator i noticed that even the smallest of electrical problems can be traced back to the alternator it might not be bad yet but it could go any time

Two questions: Is your odometer working? If not then it's probably a broken gear by the stepper motor that Emissionwiz mentioned. Is your ABS and/or TRACS light on intermittently or constantly. If so that is a common sign your ABS control module has gone or is going bad. This usually happens before the speedometer starts acting up. Either one of these will start intermittently and finally end up with the speedometer not functioning at all, and both are pretty common failures with this model.

Have you checked with your ISP on the strength and consistency of the signal before troubleshooting the router. If you're having problems with the wired connection, I would first try connecting directly to the modem to make sure you have a strong signal.
Let me know if you have a strong signal directly from the modem. We can troubleshoot the wireless router once we ensure the signal from the modem is good.
Thanks.
