1990 Eclipse Sensors Location

Here are some photos of O2 sensor I'm checking out. I had a hard time = finding it from manuals - were either wrong or diagrams hard to = understand. Maybe this will help someone else.



Other sensors are OK - anyone know what each of the other 3 are?

O2 Sensor checked out AOK. Fixed several places where the wiring = insulation was gone and loose connections - weren't causing problems yet = this time.

Here's an excellent page with great photos and clear instructions on = many repair tasks on 1G and 2G engines. Thanks for creating this site!
