What does this mean? I have already replaced the O2 sensor and it still shows this code.
My car has an automatic transmission.
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.

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.
