Code P1171 Suzuki Description
The P1171 code for Suzuki vehicles indicates a problem with the fuel supply system being too lean during power enrichment. This means that the engine is not receiving enough fuel during times when extra fuel is needed, such as during acceleration or heavy load conditions. This can lead to a lack of power, poor acceleration, and potential engine misfires. The issue typically stems from a problem with the fuel delivery system, such as a clogged fuel filter, a faulty fuel pump, a vacuum leak, or a malfunctioning fuel pressure regulator.
Common Causes of P1171 Suzuki
- Clogged fuel filter
- Faulty fuel pump
- Vacuum leak
- Malfunctioning fuel pressure regulator
- Dirty or clogged fuel injectors
Symptoms of P1171 Suzuki
- Rough running engine
- Hesitation or stumbling during acceleration
- Decreased fuel efficiency
- Engine stalling
- Check engine light illuminated
How to Fix P1171 Suzuki
- Diagnose the issue by checking fuel pressure, fuel filter, fuel pump, and vacuum lines for any leaks or clogs.
- Replace the fuel filter if it is found to be clogged.
- Test the fuel pump for proper function and replace if necessary.
- Inspect vacuum lines and intake manifold for leaks and repair as needed.
- Check and potentially replace the fuel pressure regulator if it is malfunctioning.
Cost to Fix P1171 Suzuki
The cost of repairing a P1171 code can vary depending on the specific cause of the issue. On average, the cost of parts for this repair can range from $100 to $500, with labor costs adding an additional $100 to $300.

Frequently Asked Questions about P1171 Suzuki Code
1. What are the common symptoms of OBDII code P1171 in a Suzuki related to the Fuel Supply System Lean During Power Enrichment?
- Common symptoms include loss of power, rough idling, hesitation during acceleration, and potential engine misfires.
2. What are the typical causes of OBDII code P1171 in a Suzuki indicating a lean condition during power enrichment?
- Possible causes include a vacuum leak, faulty fuel injectors, clogged fuel filter, malfunctioning oxygen sensors, or a problem with the fuel pressure regulator.
3. How can I diagnose the root cause of OBDII code P1171 in my Suzuki indicating a lean condition during power enrichment?
- Use a scan tool to monitor fuel trims, check for vacuum leaks, inspect the fuel system components, test the oxygen sensors, and verify the fuel pressure regulator's operation.
4. Can a dirty or clogged air filter trigger OBDII code P1171 in a Suzuki indicating a lean condition during power enrichment?
- Yes, a dirty or clogged air filter can disrupt the air-to-fuel ratio and contribute to a lean condition, potentially triggering code P1171.
5. Is it safe to continue driving my Suzuki with OBDII code P1171 related to the Fuel Supply System Lean During Power Enrichment?
- It is not recommended to drive the vehicle extensively with code P1171 as it can lead to poor engine performance, potential damage, and decreased fuel efficiency.
6. What are some repair tips for resolving OBDII code P1171 in a Suzuki caused by a lean condition during power enrichment?
- Repair tips include fixing any vacuum leaks, replacing faulty fuel injectors, cleaning or replacing the fuel filter, ensuring proper oxygen sensor function, and checking the fuel pressure regulator.
7. Can a malfunctioning mass airflow sensor (MAF) trigger OBDII code P1171 in a Suzuki indicating a lean condition during power enrichment?
- Yes, a malfunctioning MAF sensor can inaccurately measure incoming air, leading to a lean condition and potentially causing code P1171 to be triggered.
8. How important is it to address OBDII code P1171 in a Suzuki indicating a lean condition during power enrichment promptly?
- It is crucial to address code P1171 promptly to prevent further engine damage, ensure optimal fuel efficiency, and maintain overall vehicle performance.
9. Are there any specific driving habits or conditions that may exacerbate OBDII code P1171 related to the Fuel Supply System Lean During Power Enrichment in a Suzuki?
- Aggressive driving, extended idling, or driving with a heavy load can exacerbate a lean condition and potentially trigger code P1171 in a Suzuki.
10. Can using poor-quality fuel contribute to the occurrence of OBDII code P1171 in a Suzuki indicating a lean condition during power enrichment?
- Yes, using poor-quality fuel with inadequate octane levels or contaminants can disrupt the fuel system's operation, leading to a lean condition and potentially triggering code P1171.
