What does a high voltage code mean?
When trouble code P0138 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 the bank 1 of the engine.
What should my O2 sensor voltage be?
0.1V to 0.9V
The voltage generated from the O2 sensor should be from 0.1V to 0.9V, with 0.9V on the rich side and 0.1V on the lean side. If your readings are within this range, the O2 sensor is functioning properly.
Can I drive with a P0138 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 fix code P0463?
Some of the most common fixes for a P0463 code include:
- Repairing or replacing the fuel tank.
- Repairing or replacing the fuel level sensor float.
- Repairing or replacing the fuel level sensor.
- Replacing the wiring harness for the fuel level sensor.
- Tightening a loose connection in the fuel level sensor circuit.
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 causes incorrect readings on the O2 sensor? A leak in the exhaust system before the (O2) sensor will also cause incorrect readings.
What is the function of oxygen sensor?
– (O2) oxygen sensors are used to confirm that the proper air fuel ratio is actually reaching the engine. – Symptoms Of Bad Or Failing (O2) Oxygen Sensors. – Check Engine Light (CIL) Usually, a check engine light will provide the first indication that you might have a bad sensor. – Testing Procedures (O2) Oxygen Sensors.
