What Is Code P0134? 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.
How do I fix code P0134? What repairs can fix the P0134 code
What does code 134 mean? Code P0134 is triggered when the powertrain control module or PCM determines that the oxygen sensor voltage is hovering around 450 millivolts. If there is too little oxygen in the exhaust, it means the engine is running too rich and using excessive fuel.

Where is the oxygen sensor bank 1 located?
The 1st sensor is located closest to the engine, and the last is located towards the rear of the exhaust system. Generally, if we are talking about O2 sensors: Sensor 1 = Before Catalytic converter Front (Upstream O2 sensor)
Is bank 1 sensor 1 upstream or downstream?
Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.
What does cat mean on a code reader?
Catalyst
Catalyst (CAT) Heated Catalyst. Evaporative (EVAP) System. Secondary Air System. Oxygen (O2) Sensor.
How can I tell which O2 sensor is bad?
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 causes P0101 code?
What prompts the P0101 Trouble code
What side of engine is Bank 1?
Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine. Check out the pics below to see several different configurations. Tech Tip: The front of the engine is not the part closest to the front of the car.
What would cause a P0135 code?
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.
Is there a fuse for 02 sensor?
There are no fuses for the O2 sensors. They are controlled by the PCM.
Is Bank 1 Sensor 1 front or rear?
Therefore, in an in-line 4-cylinder engine, the term “Bank 1, Sensor 1” simply refers to the front oxygen sensor. “Bank 1, Sensor 2” is the rear oxygen sensor. A V6 or V8 engine has two banks (or two parts of that “V”). Usually, the bank that contains the cylinder number 1 is called “Bank 1.”
Can you drive with a bad oxygen sensor?
Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don’t leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.
How can you tell Bank 1 and Bank 2?
Quite simply, Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. Even on cars with a tranverse mounted engine, bank #1 is referring to downstream from the side of the engine with cylinder #1.
How do I know if I need an upstream or downstream oxygen sensor?
The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. Knowing the location of the oxygen sensor at fault is important. The number and location of the oxygen sensors are specific to every vehicle’s year, make and model.
How do I know if my upstream or downstream oxygen sensor is bad?
A decrease in fuel efficiency can be a telltale sign that an O2 sensor is not performing as it should. This can happen because of a fuel mixture that is either too lean or too rich. Such a swing in A/F ratio is a sign that an upstream or control sensor is faulty.
Which O2 sensor usually goes bad first?
The upstream sensors should fluxuate rapidly spiking up and down while the rear sensors should slowly change just slightly.
What happens if you don’t fix catalytic converter?
Because a failing catalytic converter can no longer properly convert the toxic fumes that flow through it into less harmful materials, one of the side effects that you are going to experience is the smell produced by the gases flowing through it. In particular the exhaust is going to have a sulphur type smell.
Can I unclog my catalytic converter?
You will be able to clean your catalytic converter, so long as it is not overly clogged. If it is so clogged the engine won’t run at all, then you will probably have to replace it. You may be able to find a mechanic who specializes in your make and model of car who can unclog such a converter.
Can you drive with a faulty catalytic converter?
A Catalytic Converter Can Be Driven Indefinitely
