TPS Test Harness for 1999 200 Yamaha OX66

[jdupree]

I need to test my TPS (Throttle Positioning Sensor) on my motor. Naturally, you need a test harness from Yamaha. The harness is $35.00! Does anyone have one or know where I can get one any cheaper? I know how to test the TPS but I have to have the harness. Thanks in advance!

John,

Would you know a TPS harness if you saw one?  I did a lot of troubleshooting on my OX66 a few years ago.  In some cases I just made jumpers that I could connect a DVM to, and in other cases, if I could find the proper harness cheap, I purchased it.  The harness in the pic below does not have any distinguishing markings on it, and I forget what it was specifically for, but if the connectors look like they are a match for your engine, you are welcome to borrow it.  I'll also look around the garage a bit, as I may have another test harness hiding somewhere.

Hold the phone!  I think I found it!  I have a 06857 test harness, which a quick search of the web reveals is a TPS test harness.  You will need to verify it is the correct harness for your engine (mine is a 2002 OX66 200 hp).  I don't want to sell it, but if you want to borrow it, let me know.  I think the harness above is for testing the O2 sensor.  I can lend both of them to you if you want.  Here is a pic of my TPS harness:

That is the exact one Craig!!!!!  I know you don't want to sell it and that is fine.  I think my TPS is out of adjustment or going bad.  I will pay the shipping both ways if I could borrow it?  I really appreciate you taking the time to help me out   Just let me know.

No problem, John!  Just PM me your address and I'll get it right up to you.  You have the October gathering coming up, right?  Hopefully you get the boat running good by then!
