Ls 3 Wire Temp Sensor Wiring The ls engine typically uses a 3 wire coolant temperature sensor, which provides accurate temperature readings to the engine control module (ecm). proper wiring of this sensor ensures that the ecm can adjust fuel and ignition timing based on the engine’s temperature. the 3 wire coolant temperature sensor has three terminals: signal, ground. In this video i show what sender sensor to use for your ls swap to run your gauge without a separate sender. this method uses a sender from a 1998 camaro o.
Ls 3 Wire Temp Sensor Wiring On todays video i will be showing you how i got my factory temp sensor gauge working in my square body chevy ls swap project truck using a 3 wire factory ls. 3 wire coolant temperature sensor wiring diagram. 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. in three wire coolant temp sensors, the ecu does not control the. In a previous video, we got the '91 chevy obs 5.3 running. after a short run, several issues came up. the first was the temperature gauge did not function. The ls motors (well, at least my 5.3, but i believe all) have 2 ports for coolant temp. the port located on the driver side head, toward the front is the sensor for the computer (in the newer cars the computer sends the signal to the dash, in our cars it does not). there is also a blocked off port on the passenger side head, toward the rear.

One with a simple 1 4" tang and one with a sealed metripak 150 connector. the ls motors use an m12x1.5 metric thread for the sensor. you can buy a 3 8npt to m12x1.5 adapter for ls swaps. you have to match the temp gauge to the temp sender or it will not read as accurately as they were originally setup to read. 3 wire engine coolant temperature sensor (one wire for the dash gauge, the other two for the pcm. pn 12551708). 3 wire coolant temperature sensor connector: 12102748. 2006 superior blue trailblazer ss awd, stock as a rock. sold: 2002 gmc sportside denali front end with a 2002 ls1, flt level 5, yank 2600, trick turbo, t76, nelson intercooler.
