This is a duplicate post, copied from the
Canadian FJR TPS thread. I'm looking for TPS P/Ns -- old vs new.
Today. The TPS is a wear-out item, nothing inside it breaks or burns out causing a sudden failure. Many TPS have gone the distance, but a lot haven't. You are being offered a chance to improve your long term odds at no cost with just a bit of inconvenience while they have your bike. [Edited to add -- The TPS is a low risk install, chances of the dealer bungling the job is fairly low.]
A TPS that is beginning its death march may begin with little glitches that you could overlook for some time. Looking back, my first indication that the TPS was in the beginning phase of failure was a no-start episode. Then one day while the engine was very hot it ran like crap below 4k rpm. Then the 'surging' started getting worse. In reality what I was attributing to the normal factory installed light engine load surging was actually the TPS entering the middle phase of failing. At all times my TPS passed a diAG test and an ohm test. It wasn't until I hooked a volt meter to the TPS and went for a ride that I conclusively identified the TPS as failing. While riding my bike and monitoring the TPS voltage there was an incontrovertible relationship between a voltage glitch and an engine hiccup. In went a new TPS and all symptoms have gone away. While working on my bike a couple of weeks ago I went for a ride with the DMM hooked up to the TPS and the voltage was rock solid, as was the engine performance.
I called University Motors and told them I was looking for TPS P/N 5PS-85885-00-00, but when Gary looked up the TPS for my '04 Yamaha had a new number for it, a 5PS-85885-01-00 which is the part specified for the '06 FJRs. Anyone know what P/N is being installed as part of the recall?
