The voltage at pin 5 power input is 12 volts with the battery voltage at 12.47.
There was no voltage on pin 6 the ground side, but the resistance to ground today was 361 ohms. These readings were all taken at the harness side connector with the sensor disconnected. I erased the codes and got the check engine light again, but the code was only P0030.
With a warm engine the resistance measured between pins 5 and 6 on the sensor was 4 ohms.
You asked for the voltage on the ground wire at the sensor. Do you want me to penetrate the wire insulation to get a reading while it was connected to the harness?
Ok, I will install a new sensor and let you know the results.
New o2 OEM type sensor was installed. Check engine light is now out.
