Details of the Ford p0136 OBD Code
Fault code P0136 in a Ford indicates a malfunction in the downstream oxygen sensor circuit.
OBD code P0136 for Ford vehicles indicates that the O2 sensor circuit malfunctioned in bank 1 sensor 2. This code is triggered by the Engine Control Module (ECM) when it detects that the voltage signal from the downstream O2 sensor remains stuck or inactive for an extended period.
The downstream O2 sensor, also known as sensor 2 in bank 1, is located after the catalytic converter.
It measures the oxygen levels in the exhaust gases to ensure the efficiency of the catalytic converter in reducing emissions.
When the voltage signal from this sensor remains constant or doesn’t fluctuate as expected, the ECM sets code P0136.
Mechanic’s Tech Notes
Detailed information on diagnosing and repairing fault code P0136 in Ford vehicles.
To diagnose and fix OBDII code P0136 in a Ford vehicle, start by checking the wiring harness and connectors related to the downstream oxygen sensor (Bank 1 Sensor 2).
Use a voltmeter to test the sensor’s heater circuit for proper voltage and resistance.
Inspect the connector pins for any damage, corrosion, or poor connections.
If the wiring and connectors appear to be in good condition, the issue may lie with a faulty oxygen sensor itself.
Consider replacing the downstream oxygen sensor to resolve the P0136 fault code.
