What causes a P0158 code on an O2 sensor?
What causes a P0158 code on an O2 sensor?
Potential causes of an P0158 code include: Bad o2 sensor (Bank 2 Sensor 2) Wiring in contact with exhaust components Engine running rich (If other codes are present) Holes in exhaust causing PCM to over-rich engine resulting in an abnormally high Bank 2, sensor 2 reading Short to voltage on signal circuit Bad PCM
What does p0174 mean on a bank 2 engine?
Basically this P0174 code means that the upstream oxygen sensor in bank 2 reporting a lean condition (too much oxygen in the exhaust). On V6/V8/V10/V12 engines, Bank 2 is the side of the engine that doesn’t have cylinder #1.
What are the symptoms of a P0158 DTC?
Symptoms of a P0158 DTC may include: MIL (Malfunction Indicator Lamp) on Engine loses power and misses intermittently May exhibit loss of fuel efficiency Potential causes of an P0158 code include: Wiring in contact with exhaust components Engine running rich (If other codes are present)
What does the p0174 code on a PCM mean?
When the PCM has reached it’s limit on how much fuel it will inject but the front (upstream) bank 2 oxygen sensor still detects a lean condition, the PCM will continue to command a higher than normal amount of fuel to bank 2 and will trigger this code and illuminate the MIL (malfunction indicator lamp). P0174 code shown on scanner:
What causes an engine to have a P0158 code?
Potential causes of an P0158 code include: Bad o2 sensor (Bank 2 Sensor 2) Wiring in contact with exhaust components. Engine running rich (If other codes are present) Holes in exhaust causing PCM to over-rich engine resulting in an abnormally high Bank 2, sensor 2 reading.
Basically this P0174 code means that the upstream oxygen sensor in bank 2 reporting a lean condition (too much oxygen in the exhaust). On V6/V8/V10/V12 engines, Bank 2 is the side of the engine that doesn’t have cylinder #1.
How can I tell if my car is p0171 or P01 74?
A firing order and cylinder location diagram may be needed to see which side of the engine is Bank 1 or Bank 2. P0171 is triggered by the engine bank 1 “upstream” oxygen sensor and P0174 is triggered by the engine bank 2 “upstream” oxygen sensor.
Symptoms of a P0158 DTC may include: MIL (Malfunction Indicator Lamp) on Engine loses power and misses intermittently May exhibit loss of fuel efficiency Potential causes of an P0158 code include: Wiring in contact with exhaust components Engine running rich (If other codes are present)
Which is the sensor on Bank 2 of p0152?
The “Bank 2” in the definition of code P0152 refers to the engine bank opposite bank one or the bank that does not contain cylinder one. Meanwhile, the “Sensor 1” in this trouble code’s definition points to the first sensor or the sensor before the catalytic converter on bank two.
What causes the p0159 OBD-II trouble code?
Code P0159 is a powertrain code that indicates a specific sensor in the exhaust system (bank 2 sensor 2) is not performing as it should. When an oxygen sensor modulates slowly, it is an indication it is bad. This sensor monitors the catalyst efficiency for emissions purposes. What causes the P0159 code?
What is the error code for the O2 sensor?
Error Code P0158 is defined as O2 Sensor Circuit High Voltage Bank 2 Sensor 2. This refers to a trouble in the Bank 2 Sensor 2 of the O2 (oxygen) sensor, which is located near the backside of the exhaust, behind the catalytic converter.

Error Code P0158 is defined as O2 Sensor Circuit High Voltage Bank 2 Sensor 2. This refers to a trouble in the Bank 2 Sensor 2 of the O2 (oxygen) sensor, which is located near the backside of the exhaust, behind the catalytic converter.
Where is the p0157 code on Bank 2?
The P0157 code refers to a potential problem with the #2 sensor on Bank 2 or its circuit. This code applies to the downstream oxygen sensor located right behind the catalytic converter. If your OBD-II scanner registers this code, you can either let your mechanic handle it or address the issue yourself.
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.
What is the diagnostic code for 02 sensor circuit high voltage?
Cost of diagnosing the P0158 code. P0158 is a diagnostic trouble code (DTC) for “02 Sensor Circuit High Voltage (Bank 2, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does P0158 mean on the oxygen sensor?
Therefore, the downstream oxygen sensor (sensor 2) should produce a steady voltage of approximately 0.45 volts. When trouble code P0158 is set, this indicates that there is a high voltage (steadily above .9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on bank 2 of the engine.
What does trouble code P0158 mean on a Honda Accord?
All our repairs are backed by our 12-month / 12,000-mile warranty. The P0158 trouble code appears when the sensor has remained at a high voltage for too long. This oxygen sensor is located behind the catalytic converter.
Is it okay to drive a car with P0158?
It is okay to drive a vehicle with P0158 for a short period of time, but driving with this code for an extended period of time can damage the catalytic converter (s). Replacing the O2 sensor without checking to see if the vehicle is running rich due to another problem.
