Details of the Ford p0059 OBD Code
Ford code P0059 relates to an issue with the heater circuit in the bank 2 sensor 1 oxygen sensor.
OBD code P0059 for Ford vehicles indicates an issue with the Heater Control Circuit High Voltage for the Bank 2, Sensor 1 oxygen sensor.
This code is triggered by the Engine Control Module (ECM) when it detects a high voltage condition in the heater circuit of the upstream oxygen sensor on bank 2 of the engine.
The oxygen sensor involved in this fault code is located before the catalytic converter on the side of the engine that contains cylinder 2. The ECM monitors the voltage in the heater circuit of this oxygen sensor to ensure it is within the specified range for proper operation and emissions control.
If the voltage is too high, it can indicate a fault in the heater circuit, which can affect the sensor’s performance and accuracy in measuring the oxygen content in the exhaust gases.
