P0500 Speed Sensor A (1 Viewer)

[MongooseGA]

So I thought I found my issue. Went under the truck to try disconnecting my yellobox and reconnecting the original harness. Found that my yellowbox fell from its mounting and went MIA somewhere just before I exited the highway, leaving the harness to drag on the road and get chewed up. Brilliant! I'll just hook the OEM back up and be good to go!

Nope. Still bad.

So I went through the DS footwell fuse panel. I pulled every fuse out and checked, all looked good. To my surprise, I now have no PRNDL lights or reverse lights (confirmed both of these were working prior to pulling fuses). Effin' A, now I've made it worse...

I'll go dig through the PS fuse panel now...


**Edit**

After going through the other panel, I found that it was fuse #62 mentioned earlier in the thread. Replaced it, everything is working again including speedometer.

So, I can attribute the speedometer failure to the yellowbox being destroyed, and the reverse lights/PRNDL to the 10 amp #62 fuse, but... Why would the #62 fuse on the PS panel have popped only after I'd reconnected the yellowbox and gone through the DS panel fuses? If the brake light resistors are to blame, why now and not in any of the 1700 miles the truck just did this weekend?

Ik loste dit op nadat ik mijn brandstofpomp had gerepareerd, ik besloot aan het tapijt te trekken om het te wassen en eindigde met het verwijderen van de dvd-speler van derden, de iPod-aansluiting, de omvormer en alle bijbehorende bedrading helemaal tot aan de batterij (het was allemaal rommel) . Kijk eens aan, het controlelampje dat een jaar aan is geweest en is uitgeschakeld en al meer dan 150 mijl en 10 starts is uitgeschakeld.

Ik denk dat het de splitsing in een draad was die in het contactslot ging, voertuigsnelheidssensor A kreeg misschien niet zoveel stroom als zou moeten.

Hi! do you think there is an easyer way to fix the problem? eps:

I have the same problem.
Error message p0500 on my 2005 landcruiser 100.

Unfortunately I had the speed sensor replaced ($$$) but this was not the solution.
So not I'm still with the error message and no cruise control.

I have the car read again at my garage, and that is p0500. The sensors at the wheels are good. But don't know where to look anymore. The only option is the wiring.
My question is, can you easily get there? Or does the entire floor have to be removed, as with @nsaladin?

Unless I’m mistaken the speed sensor that controls the cruise control in located in the center differential not the ABS sensors located at each wheel

Hey look! I'm back in this thread again!

Ok so mine has been acting really funny recently, and it's getting worse now.

My speedometer has been mostly non-op for most of the year. Every now and then it'll work and display correct(ed) speed, but it's rare. Enough so that if either my fiancee or I drive the truck and the speedo works, we celebrate it to the other later. Best I can tell, the stepper motors in the cluster are going bad as they flutter around sometimes at initial start-up. I can deal with it for now as I have speed on the SG and the cluster repair is $700.

Within the last few weeks, my cruise control has begun just turning itself off. I can hold speed, then it turns off and the icon blinks once or twice in the cluster. I can turn it back on and it'll work for a bit, then go out. This isn't every trip. I noticed it happening mostly at times the speedometer is operating. OK, maybe a tie there. The speedo needle will jump in 10-20MPH increments, then the cruise goes. My initial thought was that the cruise couldn't reconcile the erratic speed readings, so just turned off by default.

Over the weekend was the first time I've actually lost throttle. Almost always while accelerating at highway speed, there's just no response from the pedal for a second. Happened twice on a 3 hour drive, only occurred while using cruise.

Today I was not using cruise, speedo was non-op, and the throttle went out on the 285 perimeter. I coasted for a good 3-4 seconds before it came back. I noticed the speed at my SG was displaying 0MPH, and the truck threw the p0500 code.

I can kind of deal with the annoyance of the speedo and cruise being intermittent, but I can't deal with losing throttle while driving. The speed sensors are a cheap part and I plan to swap a new one just to be safe. Has anyone else ever just straight-up lost throttle??
