The oxygen sensor that trouble code P0157 refers to, is located in the rear of the exhaust and behind the catalytic converter. It’s main function is to regulate the amount of oxygen that comes from the catalytic converter. A lean mixture of oxygen and gas means that there is too much oxygen in the exhaust.
What causes a P0157 code?
The P0157 code is typically triggered when the powertrain control module (PCM) has detected that the oxygen sensor voltage stayed below the expected value for more than preset time.
Can I drive my car with code P0157?
What Does Code P0157 Mean? Issue Severity: MODERATE– Extended driving with this code can cause internal engine damage. Repair Urgency: Get this code fixed as soon as possible.
How do you fix a high voltage O2 sensor?
Zitat von Youtube: Make sure the new injector has new seals. And never use the old seals. Over when you change the fuel injectors. Change them all as a set otherwise the engine will run unevenly.
What causes low voltage in downstream O2 sensor?
Too low fuel pressure can cause the engine to run lean, causing the O2 sensor to read low voltage as described in step 3. In this case, the sensor is accurate, and the lean running condition needs to be fixed.
What O2 sensor is bank 2 sensor 2?
Diagnostic Trouble Code (DTC) P0158 stands for O2 Sensor Circuit High Voltage (Bank 2, Sensor 2). The O2 sensor 2 is the downstream O2 sensor and it measures the amount of oxygen in the exhaust gases leaving the catalytic converter (cat).
What is O2 sensor heater malfunction?
What Does the Code P0141 Mean? DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates that there’s a problem with the heater circuit of engine bank 1’s downstream O2 sensor. Your car’s PCM tests the oxygen sensors’ heater circuits for integrity.
Which side is Bank 2 sensor1?
Bank 2 Sensor 1 (a.k.a. B2S1) is located on the side of the engine with cylinder 2 in the firing order and the O2 sensor situated in front of the catalytic converter. Depending on the car’s make and driver orientation, it could be found on either the driver or passenger side of a vehicle.
What does low voltage on a rear O2 sensor mean?
A low voltage signal from the oxygen sensor indicates low oxygen content in the exhaust—a sign that the engine runs rich. The PCM responds by reducing the fuel going to the engine.
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.
How do you check voltage on a O2 sensor?
Zitat von Youtube: And obviously you want to put your setting on your multimeter. 2 to 2 volts. Since you know we're measuring between point zero to one wall. And also connect your wires.
