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.
What is the OBDII code on a Honda Accord?
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.
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.
What are the symptoms of service engine p0139?
Typically, the only symptom of P0139 is going to be the service engine soon light. In some cases, there can be other symptoms as well. These symptoms include: Often, the vehicle with P0139 will not pass emissions due to the higher levels of pollutants in the exhaust.
What does the DTC code p0138 stand for?
Diagnostic trouble code (DTC) P0138 stands for O2 Sensor Circuit High Voltage (Bank 1, Sensor 2). The code will set when your car’s primary computer—also called the powertrain control module (PCM)—detects that, for a given period of time, the voltage signal from the rear O2 sensor is too high.
How much does it cost to diagnose p0138 Dodge engine code?
The cost to diagnose the P0138 DODGE code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars? When is the code detected?
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.
When is the p0138 code detected in an engine?
When is the code detected? The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time. The Heated Oxygen Sensor 2 (HO2S) (Rear O2 Sensor), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank.
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.
Is there a problem with the Honda Accord p0302?
Jumps a 30kV gap looks blue enough to rule out a secondary issue. Great. MAP sensor voltage looks OK < .90v with the engine hot @ idle. Pretty much rules out a sticking valve or the valves being out of adjustment. Concur, and just about rules out engine pumping problems. That and the good compression test.
What does the DTC code p0139 stand for?
Diagnostic trouble code (DTC) P0139 stands for “O2 Sensor Circuit Slow Response (Bank 1, sensor 2).” It indicates that the powertrain control module (PCM) has detected a potential issue with the signal from the rear oxygen sensor on bank 1.

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.
What does p0171 mean on Honda fuel injection system?
P0171 HONDA Tech Notes If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced. What does this mean?
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.
