Code P2195 Mercury Description
The P2195 code for Mercury vehicles indicates that the oxygen sensor signal for Bank 1 Sensor 1 is biased or stuck lean. This means that the oxygen sensor located in the exhaust system before the catalytic converter is sending a signal to the engine control module (ECM) indicating a consistently lean air-fuel mixture. The ECM uses this data to adjust the fuel injection to achieve the optimal air-fuel ratio for combustion in the engine. When the oxygen sensor signal is biased or stuck lean, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
Common Causes of P2195 Mercury
- Faulty oxygen sensor
- Vacuum leak in the intake system
- Malfunctioning mass airflow sensor
- Clogged fuel injector
- Issues with the fuel pressure regulator
Symptoms of P2195 Mercury
- Rough idling
- Hesitation or stalling during acceleration
- Decreased power output
- Increased fuel consumption
- Check engine light illuminated
How to Fix P2195 Mercury
- Diagnose the issue using an OBD-II scanner to confirm the P2195 code and pinpoint the specific cause.
- Inspect the oxygen sensor and replace it if it is faulty.
- Check for vacuum leaks in the intake system and repair as necessary.
- Test the mass airflow sensor and clean or replace if malfunctioning.
- Inspect the fuel injectors and fuel pressure regulator for any issues and address as needed.
Cost to Fix P2195 Mercury
The typical repair costs for resolving a P2195 code on a Mercury vehicle can range from $200 to $500, including parts and labor. However, it's essential to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships and lower at independent shops.
