What is the diagnostic code for O2 sensor circuit high voltage?
P0138 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit High Voltage (Bank 1, 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.
How to check for an O2 sensor failure?
Scans codes and documents freeze frame data and then clears codes to verify failure. Monitors O2 sensor data to see if the voltage is switching back and forth between low and high at a fast rate compared to other sensors. Checks the O2 sensor wiring and the harness connections for any corrosion in the connections.
What is the OBD code for oxygen sensor?
OBD-II Code P0132 is caused by an oxygen sensor circuit high voltage (Bank 1, Sensor 1).
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.
P0138 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit High Voltage (Bank 1, 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.

OBD-II Code P0132 is caused by an oxygen sensor circuit high voltage (Bank 1, Sensor 1).
Why does my car have a low voltage sensor?
This error code is triggered by your car’s primary computer—often referred to as the powertrain control module (PCM)—when it perceives a problem with the oxygen (O2) sensor. More specifically, this means that the PCM is detecting a low voltage from the #2 O2 sensor in Bank 1.
P0132 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)”.
Is it possible to replace the O2 sensor?
Replacing the O2 oxygen sensor can be a difficult task, but if you like to delve into the components of your vehicle, you can easily replace the O2 oxygen sensor yourself. It is first advisable to switch the engine on and let it run for a few minutes.
How can I tell if my oxygen sensor is defective?
Check the output voltage at the O2 oxygen sensor with a digital voltmeter. If the sensor voltage signal is between 100 mV-900 mV (0.10 to 0.90V), it indicates that the O2 oxygen sensor is functioning properly. If the reading is outside the specified range, the sensor is defective.
When do you set an oxygen sensor voltage low?
However, what I wanted readers to get from this story is when you set an oxygen sensor voltage low code, this doesn’t mean the part needs replacing automatically. Nevertheless, a dead sensor can cause this problem, but it needs logical diagnosis. Please like and share this page with a friend.
When to replace the O2 sensor in a car?
Check voltage at the O2 sensor; if the voltage is steadily high (.9V or higher) the O2 sensor may be faulty. Before replacing, check the following: If the O2 sensor is reading high voltage and the fuel pressure and coolant temperature are within spec, replace the bank 1 downstream O2 sensor.
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.
What to do if oxygen sensor does not come back?
If the code still does not come back, you can give the customer the option of replacing the oxygen sensor as a diagnostic step since the sensor is the most likely problem and the code will presumably set again.
Why is my oxygen sensor at a high voltage?
All our repairs are backed by our 12-month / 12,000-mile warranty. When the P0132 trouble code has been stored by the power control module, it is an indication of a problem with the 02 oxygen sensor. Specifically, that the oxygen sensor has stayed at a high voltage for too long without switching back.
