What causes an O2 sensor code p0134?
The most common issues that can trigger the code P0134 include: 1 Bad or failing O2 sensor 2 Problems with the O2 sensor circuit (e.g., loose connections or blown fuse) 3 Issues with the PCM, such as software in need of an update
What causes a Kia Sorento O2 sensor to go bad?
Bad O2 Sensor – The oxygen sensor itself can go bad. This is often the cause of P0134. Replacing it without testing the wiring going to/from it first is a gamble that will often pay off, but it’s still a good idea to check your harness connections and inspect it first. Exhaust Leak – An exhaust will can cause P0134.
What is Bank 1 sensor on Kia Sorento?
P0134 affects Bank 1 Sensor 1. Bank 1 is the side of the engine that has the first piston in the firing order. That means that different model years and engine can have Bank 1on a different side.
What does no activity signal on Kia Sorento mean?
When there is no signal from this oxygen sensor, the engine will not be able to run at optimal efficiency, and you’ll get that annoying check engine light. P0134 affects Bank 1 Sensor 1. Bank 1 is the side of the engine that has the first piston in the firing order.

What are the codes for the oxygen sensor?
Got codes P0134 (Oxygen Sensor B1 S1) P0112 Intake Air Temperature Circuit Low Input P1496 5 volt supply voltage low Trying to resolve P1496 first, which is could mean any of Shorted sensor, Sensor harness issue, Sensor Circuit poor conne… My 1999 Chevrolet K1500 keeps throwing the same three codes. 1. P0134 Bank 1 Sensor 1 2.
What should I do if my O2 sensor is not working?
Replace vacuum lines or intake air tube if there are signs of cracks or disconnections. Check for any exhaust leaks between the engine and the O2 sensor. Repair as needed. Check for varying voltage of between .1-.95V with the engine running at operating temperature. If this reading isn’t within spec, consider replacing the O2 sensor 1 on bank 1
Where is the O2 sensor in a car?
The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia.
What does the error code p0134-02 mean?
Error Code P0134 is described as Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1). This means there’s a problem in the front oxygen sensor on Bank 1, as the O2 sensor is inactive.
What causes incorrect readings on the O2 sensor?
A leak in the exhaust system before the (O2) sensor will also cause incorrect readings. The only other possibilities are wiring issues, and computer concerns. A leaking or faulty fuel injector
The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia.
What is the baseline voltage of the O2 sensor?
It is essentially the brain of the engine’s control system. And in relation to Error Code P0134, the PCM provides the baseline voltage of around 450 mV on the O2 sensor signal circuit.
What does Bank 1 mean on an O2 sensor?
The Bank 1 portion of the code refers to the side of the engine with the number one cylinder (does not apply to engines with an inline configuration). Sensor 1 refers to the upstream O2 sensor (more about that below).
Why does the PCM ignore the O2 sensor signal?
The PCM ignores the signal from the O2 sensor until the sensor is warmed up. The PCM keeps track of the time it takes for an oxygen sensor to warm up. If the sensor takes longer than the PCM expects (or the sensor is not responsive), the module considers the sensor as inactive or open.
What is the code for the oxygen sensor?
Inactivity from the upstream oxygen sensor can trigger code P0134. Note: Although code P0134 is a generic code specified by the Society of Automotive Engineers (SAE), the code’s definition may be different depending on the vehicle manufacturer.
