O2 Sensor voltage readings | DODGE RAM FORUM - Dodge Truck …
2020年10月16日 · I had a code come up for my O2 sensor. I don't remember the exact code or what one of the 4 sensors it was for. Since then the code has gone away and after trying to read it again, my code reader hasn't come up with anything. I decided to watch the voltages while the truck is idling after letting it warm up.
O2 sensor bypass | DODGE RAM FORUM - Dodge Truck Forums
2020年2月15日 · Normally you want the downstream oxygen sensor voltage to be somewhere in the 2.75V-2.85V range. Looking at the scan tool or using a DVOM the sensor voltages will be in the 2.50V-3.50V range. When the oxygen sensors are hot, the O2 sensor becomes a galvanic battery that typically generates a voltage signal between 0.0V - 1.0V.

2010年10月27日 · Plug in the front o2's into the header bungs and then screw in spark plug non-foulers into the rear bungs, and the rear o2's into the non-foulers. They pull the o2 sensor slightly out of the exhaust flow and trick them into thinking there are cats there (gets rid of the CEL) This is the exact route I did (Pacesetter longtubes, no cats)

2022年3月20日 · Check the harness and chassis harness plug. Sometimes the pins get pushed out or the wire breaks inside the wire insulation. You may have to Ohm out the circuit to the PCM to make sure there is not a break. If it is an O2 sensor Heater malfunction code it could also not be recieving power. But can't really say since you didn't post the code(s).
When to change o2 Sensors? - DODGE RAM FORUM
2011年11月13日 · ^^^^^ DITTO ^^^^^. The dealership just replaced the upper and lower bank O2 sensors on MY 19 Bighorn. Rather unusual they be bad at 18,000K, but codes were thrown and would not reset on the sensor indicated, they had to replace both on same side for ECU to read and reset. Not hurt my feelings, under warranty.
