Detailed Explanation of the Sensor
The following table provides a comprehensive overview of the Bank 1 Sensor 2 in a 2015 Jeep Wrangler.
| Sensor Name | Function | Location | Measured Parameter |
|---|---|---|---|
| Bank 1 Sensor 2 | Monitors the oxygen content in the exhaust stream after the catalytic converter. | Located in the exhaust system, downstream of the catalytic converter, in the exhaust manifold. Precise location will vary based on the specific engine configuration and vehicle model. | Oxygen concentration (lambda value) |
Output Signal Under Normal Conditions
Under normal operating conditions, the Bank 1 Sensor 2 typically produces a fluctuating output signal. This signal, often represented as a voltage or resistance, reflects the changes in oxygen concentration in the exhaust gas. The signal varies proportionally to the deviation from stoichiometric air-fuel ratio. A stable signal indicates the system is working properly. A consistent signal of approximately 0.45 volts, representing a stoichiometric air-fuel ratio, is typical during normal driving conditions.
Measurement Methodology
The sensor utilizes a zirconia-based electrochemical cell. This cell’s resistance changes with the oxygen concentration in the exhaust gas. The changes in resistance are then converted into a voltage signal that the engine control unit (ECU) interprets to adjust the fuel injection. A higher concentration of oxygen results in a higher output voltage, and a lower concentration of oxygen results in a lower output voltage.
The ECU continuously monitors these readings to maintain the optimal air-fuel ratio.
