Should there be a check engine light on my '87 300e

Hi all,

I'm doing some research on this mixture problem that I'm having and I was looking through chapter 07.3-0121 (testing electrical components of KE injection system) and on page 80 it refers to a check engine light. My car has a red light labeled O2-Sensor. Is this correct?

I don't see anywhere in this chapter (testing electrical components) of a reference to an O2-Sensor light. I'm still just trying to determine WHERE to check the resistance of the coolant temperature sensor.

Thanks,

Bob
