TPS (reliable...)

[Mark Bondurant]

Simple question, is there a better TPS than Colvern that works with Jenvey ITB's?

Thanks

Very reliable and similar electrical specs to the Colvern TPS. I got tired of replacing the Colvern about 20 years ago and engineered this swap. The Colvern's failure mode is to open circuit at the most inopportune time. The potentiometer wiper leaf loses it's tension and no longer contacts the carbon sector reliably.

You will need to make an adapter for this to work. Also a female 3 pin Junior Power Minitimer connector will have to be installed on your pigtail.

Adapter drawings attached.

Awesome, thank you!

I'll post a picture in a day or so when I get time. The adapter is for the Jenvey 51mm tapered style throttle bodies, not the Weber conversion style. The mount may work on the Weber style TBs, but I'm not sure.

You use too many TLAs.  /s

TPS = throttle position sensor

ITB = individual throttle body
