Ford P0131 OBD-II Trouble Code Definition:
P0131 HO2S11 Sensor Circuit Low Voltage
P0131 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0131
O2 Sensor Circuit Low Voltage
What does the code mean? OBD-ii Code P0131 definition:
Essentially the same as P0136 and P0137, a P0131 code definition:the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor’s voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
