Code P2195 Hyundai Description
The P2195 diagnostic trouble code (DTC) for Hyundai vehicles indicates a problem with the HO2S (Heated Oxygen Sensor) signal stuck lean on Bank 1 Sensor 1. This code specifically refers to the oxygen sensor located upstream (before) the catalytic converter on the side of the engine with cylinder #1. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases and sending this information to the engine control module (ECM) for proper air-fuel ratio adjustments. When the HO2S signal is stuck lean, it means that the sensor is indicating a consistently low oxygen level in the exhaust, which can lead to a lean air-fuel mixture. This can result in poor engine performance, decreased fuel efficiency, and increased emissions.
Common Causes of P2195 Hyundai
- Faulty oxygen sensor
- Vacuum leak
- Fuel delivery issue
- Malfunctioning fuel injector
- ECM malfunction
Symptoms of P2195 Hyundai
- Poor engine performance
- Decreased fuel efficiency
- Rough idle
- Hesitation or surging during acceleration
- Illumination of the check engine light
How to Fix P2195 Hyundai
- Perform a diagnostic scan to confirm the P2195 code and identify the root cause.
- Inspect the HO2S Bank 1 Sensor 1 for proper operation and replace if necessary.
- Check for vacuum leaks and repair any damaged hoses or gaskets.
- Test the fuel delivery system for proper pressure and flow, replacing any faulty components.
- Verify the ECM operation and reprogram if needed.
Cost to Fix P2195 Hyundai
The typical repair costs for addressing a P2195 code on a Hyundai vehicle can range from $200 to $500, depending on the specific cause of the issue and the cost of replacement parts. This estimate includes the cost of a new oxygen sensor, potential labor charges, and any additional components that may need replacement. It is important to note that the actual repair costs can vary based on the location of the repair shop, the vehicle's make and model, and the type of engine. Additionally, diagnostic time and labor rates can influence the final cost of the repair. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the specific circumstances.

Frequently Asked Questions about P2195 Hyundai Code
1. What does the OBDII code P2195 mean on a Hyundai?
P2195 indicates that the oxygen sensor (HO2S) for Bank 1 Sensor 1 is reporting a lean condition that appears to be stuck, meaning the air-fuel mixture has too much air and not enough fuel.
2. What are the common symptoms of a P2195 code in a Hyundai?
Symptoms may include poor fuel economy, rough idling, hesitation during acceleration, a lack of power, or the Check Engine Light being illuminated.
3. What causes the P2195 code on a Hyundai?
Common causes include a faulty oxygen sensor, vacuum leaks, exhaust leaks, a clogged fuel injector, low fuel pressure, or issues with the mass airflow (MAF) or manifold absolute pressure (MAP) sensor.
4. Can a dirty or faulty oxygen sensor cause the P2195 code?
Yes, a malfunctioning or contaminated oxygen sensor can give inaccurate readings, causing the P2195 code to trigger.
5. How do you diagnose the P2195 code on a Hyundai?
Diagnosis involves checking for vacuum or exhaust leaks, inspecting the oxygen sensor and wiring, testing fuel injector performance, and verifying proper operation of the MAF or MAP sensor.
6. Can a P2195 code cause engine damage if ignored?
While the code itself may not directly cause engine damage, driving with a lean air-fuel mixture for extended periods can lead to engine overheating or damage to internal components.
7. How much does it cost to fix the P2195 code on a Hyundai?
Repair costs vary depending on the issue, ranging from $150–$300 for an oxygen sensor replacement to higher costs if fuel system components or sensors need repair.
8. Can a clogged air filter cause the P2195 code in a Hyundai?
A clogged air filter is unlikely to directly cause this code but can contribute to poor engine performance, which might exacerbate the lean condition.
9. Should the oxygen sensor for Bank 1 Sensor 1 always be replaced for a P2195 code?
Not necessarily. The oxygen sensor should only be replaced after confirming it’s faulty. The issue could also stem from other components like vacuum leaks or fuel delivery problems.
10. How can I prevent the P2195 code from occurring on my Hyundai?
Regular maintenance, including replacing the air filter, cleaning the MAF sensor, checking for vacuum leaks, and using quality fuel, can help prevent issues leading to this code.
