View Full Version : Help! Do I need new TPS?

09-04-09, 09:39 AM
Hi, I currently have a 240 Merc M2 EFI Jet Drive, and need to know if I need to get a new TPS (Throttle Position Sensor). When I was trying to test it, and sweep it with my multimeter, it popped off, and looks like the right gold tab inside the TPS broke off (as shown in pictures). Now I can only get a steady reading of 3.66V, and cannot get it to change or sweep at all. Do I need a new TPS, and if so where can i get one (part #?).

Sorry it took me so long to reply. I was having technical difficulties with the Internet.

You definitely need a new one. Part number is 14851004 (item number 22 in the diagram), and you can try Crowley Marine. http://www.crowleymarine.com/mercury_parts/5128/50.cfm
