code 23

[ailachami]

i keep on getting a code 23 for obd1. i checked the knock sensor and even try on a different one. the thing is that it only go on after i drive for 15-20 minutes. and if i let it sit there after start up the check engine doesnt go on.

Is it wired up to the ECU properly?

If the sensor tests good, thent he wiring or the ECU are next to check.
