What are the symptoms of the O2 sensor heater circuit?
What are the symptoms of the O2 sensor heater circuit?
The ECM detects a short or open circuit, or an excessive current draw in the heater circuit. What are the symptoms of the P0135 code? The ECM will not have any O2 sensor feedback until the O2 sensor gives an input. The engine may run rough until the exhaust gets hot enough to activate the O2 sensor to start giving an output voltage.
What should I do if my O2 sensor is not working?
Then clear the codes. Some computer systems will shut the O 2 heater circuit off until the codes are cleared. Now, with the ignition switch off, plug the test harness with the light into the vehicle’s O 2 sensor harness connection. The light should remain off until the engine is started.

Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What is the O2 sensor heater circuit for bank 1?
The O2 sensor heater circuit for bank 1 sensor 2 is used to heat the internal parts of the O2 sensor on bank 1 sensor 2 only, and the code can be isolated just to this sensor. Need help with a P0141 code? YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.
The ECM tests the O2 sensor heater circuits at first startup and detects a short or open circuit, or an excessive current draw in the O2 bank 1 sensor 2 heater circuit. What are the symptoms of the P0141 code? The engine may run excessively rich since the engine is in open loop.
Then clear the codes. Some computer systems will shut the O 2 heater circuit off until the codes are cleared. Now, with the ignition switch off, plug the test harness with the light into the vehicle’s O 2 sensor harness connection. The light should remain off until the engine is started.
What the P0135 code means. P0135 is the OBD-II generic code indicating the engine control module (ECM) has tested the O2 sensor heater circuit and has detected a problem with the bank 1 sensor 1 O2 sensor heater circuit.
