What causes a po132?
Code P0132 is triggered when the PCM detects that your heated oxygen sensor reading is too high. This happens when the oxygen sensor voltage stays above a certain threshold for a select amount of time. The code is also triggered if the air-fuel ratio stayed in a rich-biased condition for too long.
What is po138?
P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.
What does po132 mean?
What the P0132 code means. 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.
What should oxygen sensor readings be?
between approximately 0.1 and 1.0 volts
A properly functioning oxygen sensor will show a rapidly fluctuating output voltage between approximately 0.1 and 1.0 volts. The time taken for the voltage to change from 0.1 V to 1.0 V (referred to as the lean to rich response time) should be about 300 milliseconds.
Which side of a vehicle is bank 2?
It would be presumptive to simply say it is found on the passenger side (although this is predominantly true for rear-wheel drive). By definition, Bank 2 refers to the side of an engine with the cylinder firing orders 2, 4, 6, 8, 10, and 12. It is the opposite of the B1S1 (Bank 1 Sensor 1) location.
Can I drive with a po138 code?
Is Code P0138 Serious? Driving short distances is not a problem when your vehicle shows a P0138 code. However, you shouldn’t let it go long without examining the underlying cause of the code in the first place. Running the engine with a higher fuel-to-oxygen ratio does not cause immediate damage to your vehicle.
How do I know if my O2 sensor is working?
How to test an Oxygen Sensor with a Clamp-meter
- Make sure the engine exhaust system is cold.
- Switch the clamp-meter on, to ‘DC current/DC amperage’ mode.
- Put the clamp around either of the oxygen sensor heater power wires (but not both).
- Turn the engine on.
- Observe the reading, which should be between 0.25A and 1.5A.
