The coolant gauge temp sensor is a one wire sensor located on the right rear of the engine block.
It is the two wire sensor near the thermostat housing.
which are you referring to? The AIT (Air intake Temp) Sensor is located on the intake hose (the factory rubber air intake arm) it is a 2 wire sensor The Coolant Temp sensor is a One Wire on the side of the head under the distributor.
You may want to use a paper clip or small section of wire to jump over the contacts on the plug of the temp sensor. Harness side. This is done with the wire unplugged from the temp sensor. The wire that leads into the plug may be broken. If this dosent work cut the plug off and twist the wire togather. If the warning stops you found the problem.
Check the sensor connection underneath your distributor, its a single pin sensorwith a yellow and green wire to it. On this diagram, its the green sensor...
The coolant temp sensor wire comes from the firewall area. An easy way to make the temp sensor work if you can not find it is to connect the sensor directly to the battery. The sensor uses wireless technology to send its data. It might take an hour or more of driving for the sensor to reset before it starts sending data to the computer. .
most small block Chevy trucks have used a dark green wire since around 1967 for the temp sensor on the side of the head, this went till at least 1995
Both "temp gauge sensor" and also the "temp sensor for the ECM" are on the right side top of engine pointing towards the passenger doors front frame in a cross-over tube. The two wire sensor is the ECM sensor and the one wire is the gauge sensor.
First, un plug the wire at the fan, jump the wire and see if the fan does work. If it does, trace the wire back to the sensor, there are only 2 sensors, 1 for temp gauge, and 1 for the fan.
THE temp sending unit 4 the inside gauge usally has 1 wire & the sending unit 4 the Computer has 2 wires.
In most cases the single wire sensor runs a temp gauge or temp light. The double wire sensor feeds info to the vehicle's computer and operates relays for the cooling fans. This may or may not be the case for your Saturn.
it should be on the inlet manifold there will be a wire that slides over the sensor
