Ok well.. When I received my sensor, I disconnected my battery then i changed it and replug my battery. It took me 10-15 min. Went for a ride and ABS PARKE and my speedometer still not working...

 

Ok... is the code that led you to replace that sensor gone?

 

I dont have no code displaying

 

then what led you to replace the sensor? Was it damaged?

 

I was looking at the same problem like me: no speedo, abs light, park light... All of the answer was to change the abs sensor locate on the top of the rear axle.. I tried but it did not do nothing.

 

Well that is a good reason then, was the new sensor the same as the old one? same connector, same look/length?

You may have other issues causing the problem, or you may have gotten a bad part. You will need to have the ABS codes read.

 

Yea the sensor is the same as the old one. How long drive does it for the truck to recap all his info after disconnecting the battery for like 2 hours?

 

Is there another reason why the speedometer is not working? I changer the sensor locate on top of the rear diff and speedo is still not working.
I notice on my front left wheel bearing that the abs plug is out. That must be the reason for my ABS and BREAK light but not for the speedo.

 

Does the 2 sensor on the side of the transmission can affect the speedo?

 

I ordered the 2 tranny sensor and will install it today and let you guys know.
Thanks for your help
