SPEEDOMETER SOPPED WORKING WAS COMING ON AND OFF, WHEN IT GOES OFF i GET A sERVICE ENGINE SOON LIGHT

Not related. The service engine soon lite is operated by the speedometer, so it's just coincidence that it came on soon after the water pump repair.

might need a new speedometer

Take the horn fuze out

The light is set to light by milage and it is to let you know that the next service is due. This is reset by removing the rubber grommet that is to the left lower corner of the speedometer and depress the reset button.

I am assuming its not the service engine soon light it is probably the service vehicle soon light, There are 2 lights service vehicle soon upper left side, and service engine soon upper right side.

When all these come on at the same time it is the wheel bearing sensor. Usually the wheel bearing needs to be replaced which houses the sensor. A sure way to check is to press your sls button by your shifter and see if the light goes out, If it does not, u will need to have a wheel bearing put in.

If it's the service "vehicle" soon instead of the service "engine" soon, it could be the vehicle speed sensor which is in the transmission case where the differential lives, right over where the right axle goes into the transmission.

it might be your vehicle speed sensor. It affects your speedometer, your cruise control and your trans shift points. Also, your throttle position sensor (TPS) affects shift points.

Start buy spending $30 dollars on a speed sencor attached to the top of the differential that should remove the OD flashing light and the ABS Light also fix the speedo not sure about the service engine soon light that could be many other problems..Good Luck!

I would guess there is a relation between the inop speedo and the service soon light being on. Push OFF and WARM on the climate control panel and hold down together for 5 sec to read codes.engine and transmission require speed input to set engine/trans parameters accordingly. The car car is safely performing in a back up mode until repairs are made

Replacement engine put in with 51000 miles and now the engine light is on and the speedometer goes from 50 to 0 and then jerks
