88 Fiero Oil pressure sensor/sending unit location? (Page 1/1) DanMFiero88 NOV 23, 08:02 PM Hi everyone, I have an 88 Fiero with the Iron Duke. The oil pressure gage isn’t working and it appears that it’s a sensor/sending unit problem. The thing is, I can’t find it even with two searches of the engine bay, plus searching the internet. Where the heck is it, please? Thank you!
