What does the code po135 mean?
Code P0135 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.
How do I fix error code P0135?
What repairs can fix the P0135 code?
- Replacing the O2 sensor.
- Repairing or replacing the wiring or connection to the O2 sensor.
- Replacing the fuse to the heater circuit after the short is corrected.
Where are my O2 sensors located?
The sensor is typically located on the passenger side of the car, mounted directly onto the exhaust pipe near the catalytic converter. When the sensor goes bad, your car may lose up to 40 percent of its fuel efficiency, because your car will use too much gas.
What is the diagnostic code for a bad O2 sensor?
Code P0134 is triggered when your vehicle’s O2 sensor (bank 1, sensor 1) is malfunctioning. The Engine Control Module (ECM) detects that the Oxygen (O2) sensor is at a standstill and is not accurately reading the amount of oxygen in the exhaust.
What causes a po135?
The P0135 code is activated when the heating circuit in the air-to-fuel ratio sensor, also known as the front oxygen sensor in bank one, malfunctions. Code P0135 may also indicate a bad fuse, poor connection, or damaged wiring to the heat circuit sensor.
What are signs of a bad oxygen sensor?
Here are some of the most common signs that your oxygen sensor is bad.
- A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
- Bad Gas Mileage.
- An Engine That Sounds Rough.
- An Emissions Test Failure.
- An Older Vehicle.
What are the symptoms of a bad downstream O2 sensor?
What are the symptoms of a bad downstream oxygen sensor?
- A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
- Bad Gas Mileage.
- An Engine That Sounds Rough.
- An Emissions Test Failure.
- An Older Vehicle.
What are signs of a bad 02 sensor?
What is diagnostic code P0138?
When trouble code P0138 is set, this indicates that there is a high voltage (steadily above . 9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on the bank 1 of the engine.
What is code po161?
Code P0161 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 2 and detects a short in the circuit or excessive resistance in the heater circuit.
