Temp sensor to ecm. 1993 502 EFI. Is it the same sensor that GM has used for years on cars and trucks. Looks the the same but I dont know if it's calibrated the same.I had one engine starting hard last year and I found some corrosion in the connector. I work for a GM dealer and was thinking of buying one of our sensors and installing a new connector. Thinking if coolant temp was reading incorrectly might cause hard starting. I dont have a scan tool so I though this might be a good guess.

Thanks for any input.
