What can cause an O2 sensor to read near 5 volts
A Class 2 diagnostic data link provided scan tool data for the oxygen sensor that can assist in diagnosing a system or component problem. The data can read air/fuel ratio, sensor response time, voltage changes and number of switching events.... An oxygen sensor will typically generate up to about 0.9 volts when the fuel mixture is rich and there is little unburned oxygen in the exhaust. When the mixture is lean, the sensor’s output voltage will drop down to about 0.1 volts. When the air/fuel mixture is balanced or at the equilibrium point of about 14.7 to 1, the sensor will read around 0.45 volts.
