1988 Dodge D150 Erratic Speedometer

At speeds over 25 mph, the speedometer needle begins to bounce erratically and is very noisy. I think the noise is coming from the back side of the instrument panel

    Thanks Penomik! I will try that. Never thought to check to see if the cable was removeable.

Unscrew the speedometer cable from the back of the gauge and from the transmission, take the cable out of the sheath, clean it off with carb or brake cleaner, oil it and put it back in. If that doesn't do it, replace cable assembly. If that doesn't do it, pull the speedometer gear out of the transmission and check for wear. Replace if needed.

Code 15 on 1988 ram 150 without vehicle speed sensor


Code 15 relates to a failure in the vehicle speed sensor circuit. The job of the vehicle speed sensor is to inform the computer about the speed of the vehicle so the computer can calculate engine load and prepare the engine idle speed control system while the vehicle is decelerating. On deceleration, the idle speed control system will allow additional air flow into the engine as the vehicle rolls to a stop. Usually code 15 will be accompanied by erratic speedometer readings (or no reading), erratic AT gear shifting, TCC lockup clutch instability, and intermittent or complete failure of the cruise control.

Although you didn't mention it, the speedometer probably bounces also. Replacing the speed sensor on the side of the transmission should solve both your problems. Good luck

Speedometer runs erratic and transmissions drops to second gear.


The ECM or TCM may be the culprit, its also possible that a ground wire is no longer grounded or partially grounded giving you the erratic speedometer.
