What temperature do oxygen sensors need to be?
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM). In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground. The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
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 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 does a PCM heater work?
The heater circuit is energized through a relay that closes when the engine is cranked. The PCM monitors the heater circuit and will turn on the check engine light if it finds a problem.
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.
How many wires does an O2 sensor have?
Typically, heated O2 sensors have four wires – two of which go to the heater circuit and two that are power and ground for the sensor. In this case study, we are only concerned with the heater circuit. Typical O2 sensor heater circuit and connectors.
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 does bank 2 mean on a PCM?

How to know if O2 sensor is bad?
Normally, a failed O2 sensor leads to poor fuel economy, however, it’s entirely possible to experience no symptoms at all when the P0155 code shows up, except for the illuminated Check Engine Light. Still, most drivers will experience a combination of the following symptoms: 1 Check Engine Light is on 2 Decreased fuel economy 3 The engine may run rough 4 There may be a sulfur smell coming from the exhaust 5 There may be black smoke coming out of the exhaust.
Is P0155 a serious DTC?
Because the code P0155 doesn’t pose danger to the driver, it’s not considered a serious DTC. It is, however, a moderately serious code. This is because it often causes drivability issues and poor fuel economy. Plus, the longer you wait to fix it, the higher the repair costs will be. Needless to say, it’s wise to deal with this code as soon as you notice it.
