How to replace belttensioner on 99 ram 1500 5.2l

My neighbor has a 99 Ram and his abs light wouldn't go off. As a brake mechanic myself. I replaced brakes all around , in which it needed, light still on so there is some kind of sensor on top of the rear end. Replaced that and still on. The only thing that is left is the block at the master cylinder, that runs about $300.00, so my neighbor don't want to spend that much. but that is about the only thing left.

heater core is most likely the prob. its a long process to replace but can be done. replaced mine in my 99 ram 2500. remove steering column and entire dash to reveal heater core, passenger side floor area.

that's internal engine repair so if you are not a mechanic you probably want to take this to a professional.

Bring it back to the transmission shop and have them test drive it with the scanner to see if the Throttle Position Sensor (TPS) needs to be replaced. A worn TPS will case the transmission to have shifting problems, the TPE sends voltage signals to the PCM and will control the transmission shift points and firmness. If the TPS has a flat spot and the voltage is down at the point where the transmission needs to shift, there may be a conflict of shift program and needs to be addressed. Good luck and keep me posted.

On my 99 ram 1500 it is on the right side of the tranny near the end with 2 wires that unplug. I replaced it with no lose of fluid, in 2 minutes.

sounds like glow plugs or primary injectors

Could be just the sensor, could be a bad fuse, or could be bad wiring. Change the sensor, check the fuse, and check wiring, or reverse order.

Did you take a voltage reading at socket of dim one compared to bright one?

it may be a pinched wire that is know causing a short. the samething happened to me.

YOU MORE THAN LIKELY HAVE IT FIXED BY NOW BUT IT'S YOUR SPEED SENSOR. SAME THING HAPPENED TO MY 99 5 SPEED. ONCE IT WAS REPLACED IT RAN LIKE A CHAMP.
