You should never disconnect any of the PCM connectors without first disconnecting the battery negative (-) terminal. Governor pressure solenoid and sensor upgrade kit.To see what this tool looks like: Wire Piercing Probe.You should use a wire piercing probe and probe the wire a few inches away from the connector.Never probe the front of the connector.Why? Because this is the clearest indication that these ARE NOT the connector pin out charts for your particular vehicle. If one or any of the wires on your Dodge Ram DO NOT match the color stated in the pin out charts, then you should not use the pin out charts in this article.If the ECS always tells the pcm the engine is 'cold' then the pcm will always run the engine 'rich'. All engines are programmed to run rich when cold. The pcm (computer) uses it to regulate all the other engine functions. Designed using state-of-the-art technology and with customers in mind. This product is made of high-quality materials to serve you for years to come. Here are some very important safety precautions when testing the wires coming out of the PCM connectors. The ECS, engine coolant sensor is an important part. Dodge Ram 1997, Vehicle Speed Sensor by Walker Products®. Post-Cat Oxygen Sensor Input (L/D Trans Only) Start your car and allow it to run for a few minutes to ensure that the coolant temperature readings are authentic and that the engine is running efficiently.Post-Cat Oxygen Sensor Input (5.9L H/D Trans Only).Once you have verified that the wiring is accurate, reconnect the negative battery cable.The resistance values should correspond to the temperature of the engine coolant. Use a multimeter to test the sensor’s resistance and ensure that the wiring is accurate.Refer to the wiring picture for your specific sensor type to determine the correct wire links. Depending on the type of sensor, you may need to ground the sensor wire or connect it to a 1-wire and a reference voltage wire.The sensor is typically located on the engine block and is in contact with the engine coolant. Disconnect the black battery cable to prevent any electrical shocks or damage to the system.

You can consult your car owner’s manual or a repair handbook to determine the type of sensor and its wiring diagram.

Identify the type of coolant temperature sensor in your car.

Sensors are shipped directly from authorized Mopar dealers and backed by the manufacturer's warranty. Similarly, when the engine coolant temperature decreases, the sensor resistance also decreases, which sends low earth signal to the temperature gauge, and the indicator rests on the cool indication. offers the wholesale prices for genuine 1997 Dodge Ram 2500 parts. When the temperature of the coolant increases, the resistance of the sensor decreases, which sends high earth 1-wire to the temperature gauge, and you see the temperature gauge indicator fully turned to the hot indication. Higher the temperature of the engine’s coolant, the lower the resistance of the ECT sensor, and vice versa. The coolant temp sensor provides an earth signal according to the temperature of the coolant. In three-wire coolant temp sensors, the ECU does not control the temperature gauge in the cluster. The two wires, a “5-volt reference”, and a “ground wire” go to the ECU, and the third wire “Earth 1-Wire for Temp Gauge” goes to the cluster-mounted temperature gauge by providing an earth link to the temperature gauge.
