P0135 O2 sensor heater circuit bank 1 sensor 1

What does this mean? I have already replaced the O2 sensor and it still shows this code.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello. P0135 is the code for an oxygen sensor heater circuit malfunction, bank 1 sensor 1. If bank 1 sensor 1 oxygen sensor has been replaced, then it may be possible that the issue is with the wiring or connector that go to the sensor. Heated oxygen sensors use four wires, two for the oxygen sensor signal, and two for the heater circuit. I would test the wires of the oxygen sensor circuit to determine if there is proper voltage. If there is not, i would carefully examine the wiring and connector. A certified professional from YourMechanic can assist with diagnosis of the code by inspecting the car firsthand and pinpointing the underlying issue.

How to Identify and Fix Common car Problems ?

It occurs when the Powertrain Control Module (PCM) or Engine Control Module (ECM) tests the oxygen sensor heater circuit in Bank 1 and detects a problem. Here, `Bank 1 Sensor 1` refers to the upstream oxygen sensor located closest to the engine on the side with cylinder #1.
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.
Trouble Code P0325: Knock Sensor #1 – Circuit Malfunction (Single Sensor or Bank 1) — What It Means. Engine knocking (also referred to as pre-ignition or “pinging”) means that the fuel/air mixture is being ignited prematurely or incompletely.
On most in-line engines, the Bank 1 sensor 1 will be located at the engine`s front side, near the cylinder head. On most front-wheel-drive models with V6 engines, this sensor will be on the backside against the firewall. Most rear-wheel-drive cars and pickups will have this sensor on the passenger side.
One of the most common reasons is that you simply may have a faulty O2 sensor that needs replacing. If an O2 sensor receives too high of voltage, or experiences corrosion around the sensor connector, this can very easily damage the sensor and cause any of these codes to appear.
A P0135 error code may cause certain inconveniences including poor fuel economy, engine stalling, and the accumulation of carbon. Short distance drives may not result in any mechanical issues, however, it is recommended to seek repairs from a mechanic before operating the vehicle at all.
The P0030 triggers when your vehicle`s Engine Control Module (ECM) detects a fault in the heater circuit of the primary oxygen sensor on the bank 1 side of the engine. Cylinder number 1 sits on the bank 1 side of the engine, while sensor 1 is between the engine and the catalytic converter.
Code P0135 occurs when the powertrain control module tests the upstream heated oxygen sensor`s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.
and see the error code p0135. it indicates that the engine control module has tested the oxygen sensor heater circuit and detects a problem with the bank one sensor one oxygen sensor heater circuit.
A bad knock sensor may also not let the engine accelerate properly while driving on the highway, and cause the vehicle to lose fuel mileage. If you notice these things happening, you should have a certified mechanic from YourMechanic inspect why the car is slow to accelerate.
Typically, a front (upstream) O2 sensor 1 that is functioning properly will be switching from rich to lean at a fairly steady rate, creating a wavelike formation. The voltage generated from the O2 sensor should be from 0.1V to 0.9V, with 0.9V on the rich side and 0.1V on the lean side.
Bank One is always the bank where cylinder number one is located. On the Corvette it will always be the driver side. Bank Two is the passenger side. Sensor 1 on Corvettes is always the sensor that is closest to the exhaust port of the engine.
Can You Drive with a Bad Oxygen Sensor? The short answer is “Yes,” your vehicle`s engine can operate without oxygen sensors. But without them, your PCM won`t know how much fuel to inject into the engine.
Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.
We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
The oxygen sensor 2 is located on bank 2, which is the side of the engine that doesn`t contain the #1 cylinder. The bank 2 sensor 2 oxygen sensor is also referred to as the downstream oxygen sensor due to its location after the catalytic converter.
Disconnect both O2 sensors (front and rear). Start the engine and allow the vehicle to idle. After faults have stored: Cycle the ignition OFF/ON 2 times with a 10 second pause in between key cycles.
yes, there is a fuse for the o2 heaters. check all the fuses. it may also be a harness issue and needs to be checked as well.
OBD II equipped vehicles use heated oxygen sensors. Heated oxygen sensors have an internal heater circuit that brings the sensor up to operating temperature more quickly than an unheated sensor.
There are several potential causes of the HOS2 code: * The fuel/air ratio (or O2) sensor may be faulty. * The O2 sensor could have a faulty electrical connector. * There may be a short or other fault in the O2 sensor circuit wiring. * An oxygen sensor fuse may be blown.
Heating circuit is the abbreviated term for heating circuit and refers to the media-carrying line system in heating and heating technology.
A P0136 code relates to the oxygen sensor 2 which lies post the catalytic converter and monitors the catalytic converter for the bank 1 side of the engine.
Oxygen sensors are fairly easy to diagnose and replace. Typically, you cannot repair a faulty O2 sensor. It must be replaced because of the technology and materials in its housing.
Sensor 1 is the upstream oxygen sensor. It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine.

Error codes P0131 and P0151
ANSWER : Hi there:

It would be best for you to review these two links; the first describes what the P0151 OBD-II Trouble Code is and what typically causes it, and second, the P0131 code and what it means.

check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor
ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.

THIS VEHICLE HAS FAILED MARYLAND STATE EMISSIONS TWICE.
ANSWER : Hello. A common reason for code p0191 and p069e is a dirty fuel filter. The fuel filter should be replaced on your vehicle about every 2-3 years. Another reason which is just as prevalent of a cause would be a wiring fault between the Fuel Pump Control Module and Engine Control Module. There was an update released by Chevrolet to address code p0191 and p069e for your engine control module where it will be reprogrammed and recalibrated. You will likely have to call the dealership to see if your vehicle has had the reprogramming complete. P0102 Will set if the mass air flow sensor becomes faulty or too dirty. There’s also a possibility of the wiring related to the mass airflow sensor has been interrupted therefore an inspection of them must be completed. Although, sometimes cleaning the mass airflow sensor will make the Code p0102 go away. Codes p0155 and p0059 point towards a bad oxygen sensor. Both indicate there’s a problem with bank 2 sensor 1. A technician with a good scan tool will be able to verify that through the live data feeds. If the update has been done then you may benefit from the help of one of our mobile technicians who can check the wiring related to codes p0191 and p069e, inspect your mass air flow sensor for Code p0102 and also test your oxygen sensors for code p0155 and p0059. P0443 could be a cause for your bad Oxygen sensor reading. Replacing the Evap purge solenoid may cause the Oxygen Sensors to read within normal ranges again.

Check Engine Light is on. Codes are Bank 1 Sensor 1 Low-voltage, and Bank 2 Sensor 1 Low-voltage. . .
ANSWER : Hi there. What seems to be the issue is the fuel pump is not plugged in. The Oxygen Sensors are working and telling you that the system is too lean with having a low voltage reading. If it was just the upstream sensor, then it would be the wiring, however, both sensors are picking up an issue. This is why the engine is running rough and has no power. If you need further assistance with your vehicle having a loss of power, then seek out a professional, such as one from Your Mechanic, to help you.

Rough idle on acceleration displaying symptoms of a misfire, but there is no misfire codes detected. On cold starts the car is completely normal.
ANSWER : Hi there. Since you have a code for the Exhaust Gas Recirculation (EGR), the EGR could act like a vacuum leak and cause a random misfire. Remove the EGR and clean it out and then put it back on. If the symptom gets better but the engine still has a misfire, then I recommend replacing the EGR valve. The EGR valve will cause the O2 sensors to register to the computer and set a code for the O2 sensors. This is normal for the O2 sensors to work. For the EVAP issue, check the gas cap and make sure that the seal is good. Also, check the purge valve on the fuel system and see if its plugged in. Most of the time the valve gets stuck and needs replaced. If you need further assistance with your engine having a misfire, then seek out a professional, such as one from Your Mechanic, to help you.

Check engine light – O2 sensor circuit + speed sensor circuit…
ANSWER : Hi there. O2 sensor low voltage can be caused my a number of things. Mass air flow sensor was only one of them. It can be a bad O2 sensor, coolant temperature sensor, or wiring issue.

What should be done is a proper diagnosis for the Check Engine Light. Using a complete scanner rather than just a code reader gives a technician the opportunity to not only read trouble codes, but to read voltages for individual sensors. While a code reader tells you the relevant system that set the Check Engine Light on, but with a number of possible causes, the full scan tool allows checking of each individual cause. Having a proper diagnosis will help you have this repaired correctly without replacing parts that are not faulty.

What would cause 1st cylinder misfire, multiple misfire, all fuel injectors circuits open and o2 sensors heater circuit high on a 2008 Dodge Charger
ANSWER : Hello. It sounds like you may have the wrong parts installed on the car. Due to the fact that multiple people have worked on it you may have some parts that do not meet specifications. From what it sounds like to me though you either do not have an ECM in the vehicle with the correct programming or you have a connection issue. If all of the grounds are not clean and tight then that will cause this. if they are then the computer needs to be programmed to your vehicle at the dealer and that may take care of it.
