Location o the speed sensor,requires replacement

What engine speed sensor ? Location ? The vehicle speed sensor signal comes from the anti-lock brake control module , to the PCM -engine control module . Speed Information to the instrument cluster comes from the PCM on the CCD serial data bus , Suggest you google Chrysler CCD data bus . Are any warning lights lit on the instrument cluster ? ABS , Check engine etc... Sorry but I suggest you take your vehicle to a qualified repair shop that has the diagnostic tools to find the problem . http://www.cnblogs.com/shangdawei/p/3570499.html

it depends whats leaking i think it has nothing to do with the problem you have abs,tc,and hill this means its a brake problem , wheel bearing ,speed sensor on the wheels or diff,could also be a trans problem but to do something quick unplug battery for 10-15 mins restart car drive for a while does light come back on

If the speedo and odometer are not working it could be the speed sensor in the transmission. And the speed sensor could also knock out the ABS and traction control systems.
Have you had the body computer scanned for trouble codes ?

make sure your sensor is aligned properly check your connections have you driven the car since you changed sometimes you need to drive the vehicle to reprogram the speed sensor into the abs circuit these are fused circuits check your fuses

my 1989 mercedes benz 300e engine light flash on and off can any one plz tell me what the problem is my email is [email protected]

TROUBLE CODE(S) IN ABS AND TRACTION CONTROL. COULD BE SPEED SENSOR UNPLUGGED OR BAD. YOU SHOULD HAVE CODES READ AT A SHOP OR DEALER.

You need to replace the vehicle speed sensor located on the trasmission.

One of the "hall effect" sensors may have a damaged lead, or the sensor itself has failed.

IF this is a 1.8 litre engine then the throttle stop needs to be reset otherwise drive each abs wheel speed sensor in a bit and test.
