My 1987 Z-24 CEL has been flashing me lately, so I pulled a 13 out, a hard code for "Oxygen sensor signal fault - signal too low"

I bought a oxy sensor from GMpartsdirect and it should be here soon.

I think thats what it needs, any thoughts ?

Thanks in advance,

Don

That's a good start. Was just working on an s10 today with that code. It should set anytime the throttle is open more then idle and the o2 sensor reading is low for 1 minute. So it can either be an o2 sensor, a fuel delivery problem causing lean condition for 1 minute, or a wiring/ecm problem. The s10 today turned out to be the o2 sensor ground. Replaced the 02 first but still had a problem, so i located the grounds/cleaned them and cleaned the ecm connections.. After that everything seems to be normal. I also made sure the fuel supply/pressure was good before I got to changing parts.
