For those who have replaced the OTS, where did you get it from?

Same here. Would love to know. They seem to be discontinued everywhere I look

Dino's Salvage has a used one..for..One Hundred and Ninety Five dollars. LOL So...I just found one at Zip Corvettes

Parts Geek lists them for $40.43.

nice, thank you

Standard motor part number TS-437... I've used plenty of their sensors with good results. Generally the Delco sensors I've used have the same numbers etched into them somewhere as these too. I wouldn't hesitate to use it. Double check the cross reference though. This is the 3 wire version. Not sure which is on a 91.

Bought one for my 89 a week or so ago from AutoZone. Part number PS201, and was around fifty bucks.

Standard motor part number TS-437. Is this the one that feeds the analog gauge? I'm confused where the gauge and digital display derive their data.

You want the 3 wire sensor for the 91. Feeds the gauge and the ECU.

Thanks 👍
