HB280ZT Posted May 4, 2006 Share Posted May 4, 2006 Hi All, Well I looked but could not find a diagram that shows the proper wiring of a 240SX TPS to MS V3. So how is it wired? TPS wires: Red White Black MS V3 signals from relay box: Vref TPS TPS ref So which go to which? I need this to hopefully get my car running this weekend. Thanks HB280ZT Quote Link to comment Share on other sites More sharing options...
mobythevan Posted May 4, 2006 Share Posted May 4, 2006 I used a 240sx TPS. My 240sx TPS has 3 wires coming out of it to a seperate connector. These wires are connected to the relay board as follows: Red to Vref White to TPS Black to TPS ret Quote Link to comment Share on other sites More sharing options...
z-ya Posted May 4, 2006 Share Posted May 4, 2006 I would not assume that the colors are correct. I've seen aftermarket sensors with different color wire. Just about all throttle position sensors I've seen (GM, Dodge, Nissan, etc.) are configured the same way. The only difference is rotation vs resistance. - The middle wire is always Vref (it is the wiper in the poteniomerter) - The outer wires are either a positive voltage, or ground. Depending on how you connect the outer wires will determine if the resistance goes up or down when you open up the throttle. I always temporarily connect the TPS to test the rotation (be careful not to short the two outer wires together as you will be shorting +5V to ground) using the TPS calibrator in MegaTune. The "Closed Throttle ADC count" should aways be lower than the "Full Throttle ADC count". Quote Link to comment Share on other sites More sharing options...
