What does p0141 mean on a Honda Accord?

P0141 is a very common OBDII code that occurs in the Honda Accord. It is caused by a failure in one of the elements that heat the oxygen sensors, specifically bank 1 sensor 2, which is downstream from the catalytic converter. It technically stands for: The purpose of the heated element in…

What is the OBDII code on a Honda Accord?

Where is Bank 1 Circuit 2 on a Honda Accord?

Bank 1 Circuit 2 is located BEFORE the catalytic converter in the exhaust flow sequence. Most of the time with P0141, it’s going to be the oxygen sensor itself that has caused the code to trigger. Good luck finding whatever caused it in your Honda Accord.

What causes an oxygen sensor fuse to blow?

Water getting inside the heated oxygen sensor connector can cause the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.

What causes p0141 code on oxygen sensor heater?

Faulty oxygen sensor heater (most common) Circuit problems (e.g., damaged wiring, loose connections – fairly common) Issues with the PCM (e.g., software in need of an update – very rare) A circuit problem is one of the possible causes of the P0141 code.

Why is the O2 sensor on my Honda Accord not working?

Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0139 is triggering your service engine soon light. Although it is a temptation to replace it right away, it wouldn’t hurt to check out the wiring harness around it beforehand. See directly below.

Why does my Honda Accord p0139 not pass emissions?

These symptoms include: Often, the vehicle with P0139 will not pass emissions due to the higher levels of pollutants in the exhaust. That assumes that the sensor is functioning properly and isn’t the reason why the code was thrown. A poor air fuel mixture going through the catalytic converter can cause damage to it eventually.

What causes a Honda Accord to misfire at idle?

Misfire – If the air fuel mixture has gotten too far from factory specs, this can cause the Accord to misfire. Idle Issues – With the air/fuel mixture altered, the vehicle can idle erratically as the computer compensates to keep the engine running.

What is the O2 sensor code on a 2003 Honda Accord?

Our 2003 Honda Accord started showing ODBII code P0141 (O2 Sensor Heater Circuit (Bank 1 Sensor 2)). The resistance on the pins of the old sensor was still within range as measured on our electrical multimeter, but figured it was probably still the sensor anyway. It was.

What is the error code on Honda Accord EX?

I have a 2004 Honda Accord EX, 4 cylinder. The “check engine” light came on and the dealer said it was error code P0141. I read a bunch of the reviews and forums and discovered that it’s an O2 sensor attached to the catalytic converter.

What causes service engine soon light to come on on Honda Accord?

Typically, the only symptom of P0141 is going to be the service engine soon light. It should not be considered a breakdown risk. But, like anything that causes the service engine soon light to come on it is a good idea to have it fixed as soon as possible. Here are the most common issues that cause the P0141 code in the Honda Accord.

What does p0141 mean in Powertrain Control Module?

Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit. P0141 Symptoms Check Engine Light is on

When does the Check Engine light log the p0141 code?

When it detects a problem in the heater circuit for the engine bank 1’s downstream oxygen sensor, it switches on the check engine light and logs the P0141 code. Why Do Oxygen Sensors Need Heat?

What does DTC p0141 stand for in heater?

DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates a problem with the heater circuit of engine bank 1’s downstream O2 sensor. This code is part of a family of codes, listed as follows:

What is the error code on a Honda Accord?

Please try again later. The error code on this Honda is P0141. This is the code for fault at the second oxygen sensor, the sensor is not heating properly. Fortunately, this code almost always means the oxygen sensor is bad, unlike many other codes where something else on the engine is causing the problem but blaming the O2 sensor.

What causes a p0141 O2 sensor malfunction?

The reasons that may lead to the establishment of code P0141 may be the following: Defective oxygen sensor (lambda sensor) Bank 1 sensor 2 Burnt heater fuse for the second lambda probe or shorted to ground Poor electrical connection in the connector of the second lambda sensor

What does the code p0141 on a HO2 heater mean?

Code P0141 indicates the operation of the 2nd bank sensor of the 1st HO2S heater. This indicates that the ECM has detected a problem with the heater circuit of the oxygen sensor behind it. Row 1 refers to the side of the motor that has cylinder 1. Row 2 is the opposite side of the motor. If you have a four-cylinder, there will only be one bank.

How much does it cost to diagnose a Honda code?

The cost of diagnosing the P0141 HONDA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P0141 HONDA code detected?

What does code p0141 on Honda oxygen sensor mean?

P0141 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. The code is triggered when the sensor is taking too long to warm up.

Why does my Honda Accord have a p0139 code?

Here are the most common issues that cause the P0139 code in the Honda Accord. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0139 is triggering your service engine soon light.

Why does my Honda Accord have a slow O2 sensor?

The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels. The Oxygen sensors are responsible for helping the ECM meter oxygen levels in the exhaust, and helping to to create the ideal air/fuel mixture.

P0139 is a common OBDII code that occurs in many vehicles, including the Honda Accord. The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels.
