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 a P0158 sensor circuit high voltage?
Potential causes of an P0158 code include: 1 Bad o2 sensor (Bank 2 Sensor 2). 2 Wiring in contact with exhaust components. 3 Engine running rich (If other codes are present). 4 Holes in exhaust causing PCM to over-rich engine resulting in an abnormally high Bank 2, sensor 2 reading. 5 Short to voltage on signal circuit. 6 (more items)
What is the diagnostic code for O2 sensor circuit Bank 2?
P0138 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit High Voltage (Bank 1, Sensor 2)”.
2006 dodge stratus 2.7 140k obd 2 code po158 have replaced and catalytibank 2 pos. 1 and pos. 2 sensors and catalytic convertor. pcm voltage .63 volts and no burnt wires and no other codes…
What does a P0158 mean on a bank 2 sensor?
The PCM (Powertrain Control Module) then compares the post-cat reading to the pre-cat readings to determine if the catalyst is working properly. A P0158 refers to a fault at the post-cat o2 sensor on bank 2 (second sensor back on bank 2), indicating that the signal voltage is too high. The o2 sensor is a four wire sensor.
What does high voltage mean on O2 sensor?
The high voltage condition from the O2 sensor is indicating a lack of oxygen in the exhaust or other related problems, such as a leaking fuel injector or a broken up catalyst inside. Need help with a P0138 code?
What is the error code for O2 oxygen sensor?
Error Code P0138: O2 Oxygen Sensor Circuit High Voltage Bank 1, Sensor 2. Error code P0138 is described as O2 Oxygen Sensor Circuit High Voltage Bank 1, Sensor 2. This indicates there is a failure to have a low voltage output below 1.2 volts or a time period of more than 10 seconds, which signifies no oxygen in the exhaust.
Why does my O2 sensor have a negative voltage?
If the Oxygen O2 Sensor signal ever goes to a negative voltage, or in excess of one volt, this is indication that the sensor is bad. These inconsistent readings are often the reason to believe the circuit is losing voltage or ground into the O2 Sensor circuit.
How many volts does a Chrysler O2 sensor use?
The same holds true for Chrysler, but these use a different O2 bias voltage, which is usually 2.00 to 4.00 volts. 1) A few key issues are very important in the analysis of O2 sensor signals. 2) An O2 sensor will cycle between 0.10 to 0.90 or almost 1 volt.

Why is the bank 2 sensor reading high?
Possible Causes. Potential causes of this error code are: Bad Oxygen sensor. Exhaust holes causing the PCM to read over-rich which results to abnormally high reading in Bank 2 Sensor 2. Wiring in close contact with exhaust components causing it to chaff or melt and exposed. Engine running rich.
Why is my oxygen sensor reading too high?
It involves the vehicle’s oxygen sensor, specifically the #1 sensor on Bank 1. This code is triggered when the PCM or powertrain control module detects that your heated oxygen sensor reading is too high. This can indicate that the oxygen sensor is responding too slowly to the air-fuel mixture in your engine.
What causes an O2 sensor to read over rich?
Exhaust holes causing the PCM to read over-rich which results to abnormally high reading in Bank 2 Sensor 2 Wiring in close contact with exhaust components causing it to chaff or melt and exposed As with other trouble codes, mechanics diagnose this code with the help of an OBD-II scanner to get all present codes that have been stored to the PCM.
Is the OBDII O2 sensor a voltage sensor?
A very important thing to note. Sensor 1 on this engine IS NOT a O2 Sensor, it is a AIR/FUEL RATIO SENSOR!!! This sensor works very differently than a O2 Sensor, it outputs a steady voltage, it DOES NOT swing rapidly like a O2 Sensor.
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.
How does the PCM work with the O2 sensor?
The PCM, after receiving these voltages, does its ‘little song and dance’ and translates the voltage amount (depending on the exact voltage the O2 sensor is producing) as either to much fuel is being injected or not enough. Here are some more specifics:
