2002 Nissan Pathfinder Question: coolant temperature sensor
Answer #1patrick mannion from Greg Solow's Engine Room, May 04, 2009, 21:06Master
There are two temperature switches on is for the operation of the temperature gauge and the other switch tells the fuel injection computer the temperature of the engine coolant.
The Fuel injected related switch is at the back of the engine (passenger side) It has a light green and red wire and a black wire at the switch.
The temperature gauge switch has a single wire on the switch yellow and red wire at the switch.
