The crankshaft sensor on the 1997 Dodge Ram 5.9-liter engine sends a pulse signal to the powertrain control module (PCM), which tells the PCM the rpm of the engine (engine speed) and the position of the crankshaft. The 5.9-liter engine is a V8 and the crank sensor is located on the right side of the block, just above the oil pan. It is a black plastic part that is held onto the block with a metal bracket. The sensor and the bracket is one piece.

Step 1

Disconnect the wiring harness connector on the crankshaft sensor. Remove the nut that holds the bracket to the fuel rail-mounting stud.

Step 2

Unbolt the other bolt in the bracket, then remove the sensor and bracket from the engine.

Step 3

Install the new sensor and tighten the bolts firmly. Do not over tighten the bolts, as you could damage the sensor. Plug in the wiring harness connector.
