What’s the fault code on a Toyota Tocoma?
The fault code is P0031-Oxygen sensor heater control circuit, Low voltage (Bank 1, Sensor 1). So that has to mean that the problem is limited to that one sensor, the Air/Fuel ratio sensor. And NOT the O2 sensor. Also, I checked the Voltage at the A/F Heater relay and it was 12v. So..still got to check that wire. those wires. Ahhhh!
