Hi, just want to check something here.
Last week I measured the OX1 pin(against GND) just to see if the voltage would be like in the above range. 0.4V - 0.8V
I got a value starting (cold) around 0.4V, but once warmed up, it went up to 1.8V on idle with the occasional drop to 1.0V.
My question is whether a wideband O2 sensor would have different readings? (Car has piggyback ecu) Or would the values just be lower and higher (0.1V to 1.2V) for example?
Don't know whether or not my car already has a wideband sensor, that's why.
Any info would be greatly appreciated.
