Hi guys:

I just installed an FJO Wideband O2 kit and noticed that TPS voltage at idle speed jumped to 0.86 volts and idle was was strangely rough. Before installing this piece of equipment, TPS voltage at idle was set at 0.45 volts and idle speed was perfect. I tried adjusting the TPS but the closest i could get was 0.65 volts?

Has anyone experienced this before? I have no check engine lights whatsoever.

Ok, here's an update. The way it was connected, i get normal expected lambda readings, but my TPS voltage is all screwed up and idle due to this is erratic. I interchanged the signal wire/ground wire on the wideband and my TPS voltage goes back to 0.45 volts, idle is perfect, but i don't get lambda readings. What is wrong here? I got an O2 sensor plug (as hondata recommends) and extended wiring so that i could connect the plug from the stock wiring harness to the signal/ground wire on the wideband O2. I connected the two wires as indicated.


Any input will be appreciated.

 

anyone?
