What is the p0155 code for the oxygen sensor?
To ensure that the oxygen sensors operate at the right time, the PCM tests the heater circuits regularly. 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.
Can a heated oxygen sensor cause a malfunction?
If you drive a fairly modern vehicle, it might be equipped with a heated oxygen sensor (HO2) instead of a regular oxygen sensor. The former contains a heating element that brings the sensor up to operating temperature faster than the latter. However, HO2s are not invulnerable and can trigger a host of trouble codes, including a P0155.
What is the OBD code for an oxygen sensor?
Repair short or open or high resistance in wiring harness or harness connectors Replace oxygen sensor (cannot repair open or short that occurs internally to sensor) Volvo 1999 S80T6 Check engine light came on. OBD II codes P0135 along with P0155.
What do you need to know about DTC p0498?
Because DTC P0498 refers to the CCV circuit, you will need a DVOM (digital volt-ohm meter) and a repair manual or electrical wiring diagram to evaluate the circuit between the ECM and the CCV, as well as the valve itself. Depending on how easily accessible the ECM and CCV are, you can start your diagnosis wherever is easier.

What are the symptoms of powertrain code p0155?
Code P0155 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 2 and detects a short in the circuit or excessive resistance in the heater circuit. What Are The Symptoms Of Code P0155?
What does the trouble code p0135 stand for?
The trouble code P0135 is a generic powertrain code indicating a problem in the front oxygen sensor on Bank 1, a heated oxygen sensor circuit that decreases time to enter closed loop. It is necessary to use an OBD-II scanner to obtain trouble codes and then check the indicated parts. Check Your Check Engine Light OBD Scan Tools & Code Readers
Can a ho2s heater cause a p0155 code?
From an open HO2S heater ground circuit to a defective HO2S heater, many issues can trigger the P0155 code. Unless you are an automotive expert, making an accurate diagnosis can be difficult. So it’s best to let a professional handle the task.

What does the code mean on the O2 sensor?
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.
Where is the O2 sensor p0135 located?
In case you’re wondering, where the oxygen (O2) sensor that the code P0135 is accusing of being bad is, this bad boy is located on the exhaust manifold and before the catalytic converter. What Tools Do I Need To Test Codes P0135, P0141, P0155, P0161?
How to troubleshoot p0135, p0141, and p0161 DTCs?
Troubleshooting DTCs P0135, P0141, P0155, P0161 is not hard and in this tutorial, we’ll look at some of the basics you need to know and what tests you need (to solve the oxygen sensor problem these diagnostic trouble codes indicate).
Why is my Check Engine light on code p0135?

When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
How does the O2 sensor in a car work?
The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer.
What does code p0155 on an oxygen sensor mean?
What Does Code P0155 Mean? Heated oxygen sensors contain heating elements to help them get to operating temperature quickly in order to minimize the amount of time spent in open-loop operation (A fixed rich mixture).
What happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.
From an open HO2S heater ground circuit to a defective HO2S heater, many issues can trigger the P0155 code. Unless you are an automotive expert, making an accurate diagnosis can be difficult. So it’s best to let a professional handle the task.
