O2/ECU Question
I have a 90 CRX D15B2
If the ECU looses oxygen sensor signal what does the ECU do to compansate? Will it just default to 450mV or somthing?

Re: O2/ECU Question (NH88TSI)
check engine light will come on and ECU should enrich mixture as a fault or 'limp home' mode. if ECU loses O2 sensor signal, it does not revert to anything, just see's a problem and illuminates light and fuel mileage will suffer.
Hope that helps...
