What's po155?
Diagnostic trouble code (DTC) P0155 stands for ”O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1).” It is triggered when the vehicle's computer or the engine control module (ECM) detects an unexpected voltage condition or excessive current draw on the heater circuit of your vehicle's Bank 2 HO2.Oct 29, 2021

Which side is bank 2 sensor 2?
All oxygen sensors are located on the exhaust system, Bank 2 for your engine will be the bank of cylinders closest to the front of the car. Sensor 2 will be the second oxygen sensor downstream on that side of the exhaust pipes, after the catalytic converter.
What side is bank 2 sensor 1?
Bank 2 Sensor 1 is the first sensor closest to the engine. On Bank 2 means it is at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine's exhaust pipe, usually behind the catalytic converter. On Bank 2 means it is at the engine side with cylinders 2, 4, 6, 8, etc.Apr 3, 2022
What is the code P1131 Ford?
Trouble code P1131 means that the powertrain control module has detected a lean condition for engine bank No. 1. Code P1131 can be caused by a vacuum leak, fuel injector problem, ignition problem or by a faulty oxygen sensor.
Should I replace both oxygen sensors at the same time?
It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors.
What does code po430 mean?
Code P0430 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.Mar 6, 2018
What is the difference between a heated and unheated oxygen sensor?
The only difference between the two is that the three-wire sensor shares a common ground between the heater and sending circuits. Therefore, a heated oxygen sensor is more efficient than an unheated sensor.
Where is the oxygen sensor located?
These sensors are always located in the exhaust gas flow of your vehicle. Most cars have one O2 sensor located close to the engine, typically in the exhaust manifold. Some cars have two O2 sensors or more, and the second Oxygen sensor is typically installed behind the catalytic converter.Apr 3, 2022
Can you clean an O2 sensor?
There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors.Mar 5, 2015
Is bank 2 before or after the catalytic converter?
The first sensor is close to the engine and the last at the rear of the exhaust system. If we are talking about O2 sensors, Sensor 1 is before the Catalytic Converter Front and Sensor 2 is after the Catalytic Converter Rear.
What are the symptoms of a P0155 code?
The only symptoms you are likely to experience when a P0155 code pops up are the following: Check engine light is on. Decreased fuel economy.
What is the code for engine bank 2?
If it detects an issue in the heater circuit for the engine bank 2’s oxygen sensor, it activates the Check Engine Light and sets the P0155 code. Vehicles that are prone to code P0155 include various models of Jeep (especially Jeep Grand Cherokee), Chevrolet, Ford, GMC, and Toyota.
What is the sensor 1 on a catalytic converter?
To raise their temperature quickly, they rely on PCM-controlled heating circuits. Sensor 1 is the heated O2 sensor unit located upstream of the catalytic converters. It determines if the component is breaking down the pollutants generated by the engine by monitoring the oxygen levels in the converter’s exhaust.
What Does Code P0155 Mean?
OBD-II Trouble Code P0155 Description O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
Symptoms of Code P0155
Compared to most engine codes, a code P0155 doesn’t really have any noticeable symptoms. Of course you’ll have the check engine light that alerted you to the problem, but unless you hook up an emissions tester, you likely won’t notice anything else.
Causes of Code P0155
By far the most common cause of a code P0155 is a faulty oxygen sensor.
Is Code P0155 Serious?
Outside of elevated emission levels, not too much happens from a code P0155. Because of this, P0155 is one of the least serious engine codes you can get. Still, even if this diagnostic trouble code doesn’t cause any immediate problems, that doesn’t mean you should ignore it indefinitely.
How to Fix
Typically all you need to do to fix a code P0155 is replace the faulty oxygen sensor. However, before you start replacing sensors, keep in mind that it could be an electrical problem. Check the wiring and test for power at the sensor to ensure that’s not the problem.
How much does it cost to diagnose a P0155?
The cost to diagnose the P0155 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
What does the code on a heated oxygen sensor mean?
Tech Notes. What does this mean? The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The Engine Control Module (ECM) monitors how long it take the sensor to warm up and start sending an adequate signal. The code means the the sensor is taking too long to warm up.

What does P0155 mean?
What Does Code P0155 Mean? The upstream oxygen sensor (O2S) is located ahead of the catalytic converter. It is used to determine the concentration of oxygen in the exhaust gas. This information is used by the PCM to control the engine air/fuel mixture.
What is the code for a P0135?
Code P0135 is the most closely related code to P0155. It stands for 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1). So, it is essentially the same code, but for the opposite bank of the engine. All of the same diagnostic steps apply.
What does bank 2 mean on a PCM?
Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. If you’ve got a four-cylinder, there will only be one bank, and you would not get this code. A typical heated oxygen sensor.
