What does a code p0134 on an oxygen sensor mean?
A code P0134 may mean that one or more of the following has happened: Bad O2 (oxygen) sensor. Bad heater circuit in the O2 sensor. Wiring or connector to the sensor frayed / broken.
What does it mean when your ECU says p0172?
P0172 indicates that there is too much gasoline being detected in the exhaust gases exiting the combustion chamber. The ECU uses a number of instruments, such as the mass air flow sensor (MAF), oxygen sensors, and manifold absolute pressure (MAP) to monitor the air-fuel ratio of the engine.
What causes the p0172 OBD-II trouble code?
What causes the P0172 code? A dirty mass air flow sensor overstating the amount of air entering the engine which may cause excessive fuel delivery A faulty fuel regulator, which may not be regulating the pressure of the going to the engine as it should
What happens if the p0172 code is too rich?
If the the air-fuel ratio is rich enough, a black smog will come out of the exhaust, which is harmful to the environment. What repairs can fix the P0172 code? It is highly recommended to check the condition of the spark plugs and the operation of the coolant temperature sensor. Need help with a P0172 code?
What does the code p0134 on the ECM mean?
Code P0134 is triggered when your vehicle’s O2 sensor (bank 1, sensor 1) is malfunctioning. The Engine Control Module (ECM) detects that the Oxygen (O2) sensor is at a standstill and is not accurately reading the amount of oxygen in the exhaust.
What causes the O2 sensor to set the p0139 code?
The code is set if the O2 sensor for bank 1 sensor 2 does not respond to the fuel cutoff for 7 seconds or more. This can be caused by excessive fuel still in the exhaust stream from possible leaking in the fuel injection system. What are the symptoms of the P0139 code?
What are the possible causes of the p0340 code?
P0340 Possible Causes. Faulty Camshaft Position Sensor. Camshaft Position Sensor harness is open or shorted. Camshaft Position Sensor circuit poor electrical connection. Faulty starter motor. Starting system circuit. Dead (Weak) battery.
What causes the p02a00 OBD-II trouble code?
What causes the P02A00 code? 1 Failed O2 sensor 2 Failed electrical connector at the O2 sensor 3 Blown fuse in O2 sensor circuit 4 Low or excessive fuel pressure 5 Vacuum leak 6 Faulty or shorted wiring in O2 sensor circuit 7 Exhaust leaks
Why is the oxygen sensor signal not detected?
Basically the oxygen sensor is inactive. Here’s why: The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit. When cold, the PCM detects the the internal resistance of the sensor is high.
Why is the oxygen sensor on bank 1 inactive?
Although generic, the specific repair steps may vary depending on make/model. This code refers to the front oxygen sensor on Bank 1. Basically the oxygen sensor is inactive. Here’s why: The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit.
What to do if your O2 sensor is bad?
Bad heater circuit in the O2 sensor Wiring or connector to the sensor frayed / broken Blown heater circuit fuse Holes in the exhaust system The most common fix is to replace the oxygen sensor. But that doesn’t rule out the possibility of:
Where is the oxygen sensor on a Nissan Quest?
Here is the location of the upstream O2 sensor or Bank1 Sensor1 on a Nissan Quest. The downstream oxygen Bank 1 Sensor 2 sensor has to be accessed from underneath the engine. You will need to remove the bottom splash shield. Disconnect the oxygen sensor electrical connectors.
How to change the oxygen O2 sensor on a Nissan?
How to Change the Oxygen O2 Sensor on a Nissan In this guide, you will find instructions on how to replace the oxygen sensor on a Nissan, also known as the O2 sensor. While the pictures in this guide are from a Nissan Quest, they apply to other Nissan models, including the Altima, Maxima, Rogue, and Frontier.
What to do when your oxygen sensor fails?
When the oxygen sensor fails on your Quest, you may notice some or all of the following issues: Park your Nissan Quest and open the hood. Your browser does not support the video tag. Disconnect the negative battery terminal. Locate the oxygen sensor on your Nissan Quest.
Where is the oxygen bank on a Nissan?
The downstream oxygen Bank 1 Sensor 2 sensor has to be accessed from underneath the engine. You will need to remove the bottom splash shield. Disconnect the oxygen sensor electrical connectors.
A code P0134 may mean that one or more of the following has happened: Bad O2 (oxygen) sensor. Bad heater circuit in the O2 sensor. Wiring or connector to the sensor frayed / broken.

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.
What is the fault code for oxygen sensor?
OBD II fault code P0134 is defined as “ Oxygen (0 2) Sensor Circuit – No Activity Detected (Bank 1 Sensor 1)”, and is set when the PCM (Powertrain Control Module) does not detect a signal voltage from the oxygen sensor.
Although generic, the specific repair steps may vary depending on make/model. This code refers to the front oxygen sensor on Bank 1. Basically the oxygen sensor is inactive. Here’s why: The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit.
