How does the heated oxygen sensor ( ho2s ) work?
The sensor compares amount of oxygen in the exhaust to the surrounding air (there is an opening in the sensor that is exposed to the atmosphere). It generates a corresponding voltage which is transmitted to the PCM. The PCM then controls injector pulse based on this value. Modern vehicles use a heated oxygen sensor (HO2S).
What is the code for heated oxygen sensor?
P0135 – Heated oxygen sensor (HO2S) 1, bank 1, heater control – circuit malfunction Trouble Code Fault Location Probable Cause P0135 Heated oxygen sensor (HO2S) 1, bank 1, h Fuse, wiring, H025, ECM
What does a p0135 Honda O2 sensor malfunction mean?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. P0135 HONDA Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal.

Is the code p0155 the same as p0135?
Code P0155 is the most closely related code to P0135. It stands for 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1). So, it is essentially the same code, but for the opposite bank of the engine.
Cost of diagnosing the P0135 code. P0135 is a diagnostic trouble code (DTC) for “O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the Check Engine code p0155 mean?
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 does trouble code bank 1 sensor 1 mean?
Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1) What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. This code refers to the front oxygen sensor on Bank 1.
What does the DTC code p0135 stand for?
Diagnostic trouble code (DTC) P0135 stands for “Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1).” It is set when the car’s primary computer—also called the powertrain control module or PCM—determines that the heated oxygen sensor (HO2S) 1 heater current is higher or lower than the ideal amp for a certain amount of time.
When do you have an oxygen sensor malfunction?
But if the voltage of an oxygen sensor drops to under 400 millivolts for at least 2 minutes, then it could mean you have an oxygen sensor heater circuit malfunction in bank 2, sensor 1. If you were to run a diagnostic scan on the engine control module, it should give you trouble code P0135 to confirm this.
