Also known as an oxygen sensor, O2 sensor or lambda probe, the pre-catalyst sensor provides the engine control unit (ECU) with important information about combustion conditions. By measuring residual oxygen in the exhaust gases, the sensor allows the ECU to determine whether the engine is operating richer or leaner than intended.
The ECU uses this feedback to make appropriate adjustments to fuel delivery. Accurate lambda control contributes to smooth engine performance, efficient fuel consumption, controlled emissions and effective catalytic converter operation.
Because the sensor operates directly in the hot exhaust stream, it is continually exposed to extreme temperatures, vibration, moisture and combustion deposits. Over time, the sensing element can become contaminated or slow to respond, while the internal heater, wiring and electrical connections may also deteriorate.
Replacing a confirmed faulty LEFT Lambda Sensor 95860613301 helps restore accurate mixture feedback and reliable engine-management operation.
What This Product Does:
- Measures oxygen content in the exhaust gases.
- Fits the LEFT-side exhaust system where specified.
- Operates BEFORE the catalytic converter.
- Sends exhaust-mixture information to the ECU.
- Helps determine whether combustion is rich or lean.
- Supports closed-loop fuel control.
- Allows the ECU to make appropriate fuel corrections.
- Helps maintain the intended air-fuel mixture.
- Supports smooth idle and consistent engine performance.
- Helps maintain responsive acceleration.
- Contributes to efficient fuel consumption.
- Helps control exhaust emissions.
- Supports effective catalytic converter operation.
- Provides information used for engine diagnostics.
- Replaces a slow, inaccurate, contaminated or failed lambda sensor.
Symptoms Of Wear Or Failure:
- Check engine or engine-management warning light.
- Lambda or oxygen sensor fault codes.
- Left-bank oxygen sensor faults.
- Rich or lean mixture fault codes.
- Increased fuel consumption.
- Rough or unstable idle.
- Engine hesitation.
- Poor throttle response.
- Reduced engine performance.
- Uneven engine operation.
- Engine misfires.
- Difficult starting.
- Increased exhaust emissions.
- Failed emissions test.
- Strong fuel smell from the exhaust.
- Slow lambda response during diagnostic testing.
- Implausible oxygen sensor readings.
- Intermittent sensor operation.
- Oxygen sensor heater circuit fault.
- Damaged or heat-affected wiring.
- Corroded or damaged electrical connector.
Why Replacement Matters:
- The before-catalyst lambda sensor plays an important role in maintaining the correct engine air-fuel mixture.
- Once the engine reaches the appropriate operating conditions, the ECU can use lambda feedback to continuously refine fuel delivery. The sensor needs to react accurately as engine load, speed and operating conditions change.
- A worn lambda sensor does not always stop functioning completely. Instead, it may become progressively slower or less accurate.
- Replacing a confirmed faulty LEFT Lambda Sensor 95860613301 helps restore accurate exhaust feedback and allows the ECU to manage fuelling correctly.

Function:
The Oxygen Sensor (also known as Lambda Sensor) is located in the exhaust manifold and measures the amount of unburned oxygen in your engine's exhaust. Based on the amount of oxygen, it sends a signal to your engine computer which then adjusts the air/fuel mixture for optimum engine performance and emission control.
Failure Symptoms:
Excessive fuel consumption, a faulty oxygen sensor can waste 30% of your fuel.
Driveability problems, such as engine surging or hesitation.
High hydrocarbon emissions, failing an emissions inspection.
The engine warning light may be on or service flag displayed.
The ecu/computer stores a mixture-related fault code.
When the oxygen sensor has stopped functioning completely, the catalytic converter may overheat and fail
Maintenance/Service:
Test and/or replace every 30,000 miles.
Perform periodic emission checks.
Watch for service light.
Vehicle manufacturers recommend periodic inspection and replacement of oxygen sensor.
