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.
How do I fix error P0138?
What repairs can fix the P0138 code?
- Replacing the O2 sensor for bank 1 sensor 2.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
- Replacing the catalyst in front of the sensor.
- Repairing a leaking injector.
Can I drive with P0138?
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.
What causes a P0138 code?
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.
Where is oxygen sensor on Saturn Ion?
One sensor is located at the base of the exhaust manifold where it contacts the exhaust system, and another approximately two feet down the exhaust tubing from the flange. Disconnect the electrical connection on the oxygen sensor that you want to replace with your hands.
Is P0138 serious?
What Does Code P0138 Mean? Issue Severity: MODERATE – Extended driving with this code can cause internal engine damage. Repair Urgency: Get this code fixed withing the next month to prevent internal engine damage. Diagnosis: It is important to complete the entire diagnostic process when diagnosing the P0138 code.
Which 02 sensor is bank 1 sensor 2?
Bank 1, Sensor 2 is the downstream oxygen sensor located in the exhaust behind the catalytic converter. The engine bank that contains cylinder 1 is called Bank 1. V6 and V8 engines have two banks and two catalytic converters, one for each bank.
Can an exhaust leak cause a p0138 code?
An exhaust leak can also cause this code to appear, but if you have replaced the exhaust system, then that is ruled out. If you need further assistance with your check engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.
What is a P0141 code?
Code P0141 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.
What does the code P0113 mean?
When the error code P0113 is triggered, it indicates that the powertrain control module (PCM) has received a higher voltage signal than expected from the intake air temperature (IAT) sensor, indicating a problem with the IAT sensor 1 or its circuit.
