CEL code: O2S (HO2S) S1 Voltage High
Hi all i need help, my engine is a D16Z6 year 92 Civic SI.
Before this there was a bogging at 2500 RPMs n 2 CEL code came out saying
fuel supply too rich and fuel supply too lean.
After changing to a 2nd hand O2 sensor which a fren swore is in good working condition, CEL code now reads: O2S (HO2S) S1 Voltage High but the bogging totally dissapeared. Feels much better n runs like normal.
I had resetted the ECU a few times but this CEL code O2 sensor Voltage high still this comes out.
At the start of this prob, i had cleaned the IACV and the throttle body, changed the engine oil n oil filter and changed new spark plugs.
Anyone has any knowledge to share for solving such probs?
