P1164 2000 Honda Civic Code - Air/Fuel Ratio Sensor 1 Range/Performance Problem

Quick Answer

The Air/Fuel Ratio (A/F) sensor 1 is installed in the exhaust system and detects oxygen content in the exhaust gas. Common causes include Faulty Air/Fuel Ratio Sensor 1, Air/Fuel Ratio Sensor 1 harness is open or shorted, Air/Fuel Ratio Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1164 2000 Honda Civic Description

The Air/Fuel Ratio (A/F) sensor 1 is installed in the exhaust system and detects oxygen content in the exhaust gas. The A/F sensor transmits output voltage to the Engine Control Module (ECM). A heater for the sensor element is embedded in the A/F sensor (sensor 1). It is activated and heats the sensor to stabilize and speed the detection of oxygen content by controlling current flowing through the heater. An increase in the current levels off as the applied voltage to the element electrode reaches a certain range because the amount of oxygen which is led through the diffusion layer is limited. The current amperage is proportional to oxygen content in the exhaust gas, so the air/fuel ratio is detected by the measurement of the current amperage. The ECM compares a set target air/fuel ratio with the detected air/fuel ratio and controls the fuel injection timing.
If the A/F sensor (sensor 1) voltage is low, the air/fuel ratio is lean, and the ECM uses A/F feedback control to issue a Rich command. If the A/F sensor (sensor 1) voltage is high, the air/fuel ratio is rich, and the ECM uses A/F feedback control to issue a Lean command.

Frequently Asked Questions about P1164 2000 Honda Civic Code

1. What does the OBDII code P1164 indicate on a 2000 Honda Civic?

The code P1164 indicates that there is a range/performance problem with the Air/Fuel Ratio Sensor 1, suggesting the sensor is not operating within the expected parameters set by the manufacturer.

2. What are common symptoms of the P1164 code in a 2000 Honda Civic?

Common symptoms include a check engine light, poor fuel economy, rough engine idle, and possibly engine misfiring.

3. What can cause the P1164 code to appear in a 2000 Honda Civic?

Potential causes include a faulty air/fuel ratio sensor, wiring issues related to the sensor (such as shorts or open circuits), or problems with the engine control module.

4. How do I fix the P1164 code in a 2000 Honda Civic?

To fix this code, start by inspecting the air/fuel ratio sensor and its wiring for any visible damage or disconnections. If the sensor and wiring appear intact, consider replacing the air/fuel ratio sensor.

5. Is it safe to drive a 2000 Honda Civic with the P1164 code?

While you can drive the vehicle, it's not advisable to do so for an extended period. The issue can lead to increased fuel consumption, reduced engine performance, and potentially more serious engine problems.

6. How do I verify the repair was successful after fixing the P1164 code?

After repairing, clear the code from the ECU using an OBDII scanner and take the car for a test drive. If the code does not return and the car performs well, the issue is likely resolved.

7. What tools are needed to diagnose the P1164 code in a 2000 Honda Civic?

You will need an OBDII scanner to read the code and possibly a multimeter to check the sensorâ€™s wiring and voltage.

8. Could the P1164 code be a result of a previous repair or unrelated vehicle modification?

Yes, if recent repairs involved the engine or exhaust systems, improper reassembly or incorrect part replacement could trigger this code. Additionally, modifications that affect the engine's air-fuel mixture might also cause this issue.

9. What is the cost implication of resolving the P1164 code in a 2000 Honda Civic?

The cost can vary based on the exact cause. Replacing an air/fuel ratio sensor can range from $200 to $400 including parts and labor, depending on the service location and sensor brand.

10. How urgent is it to address the P1164 code on a 2000 Honda Civic?

It is moderately urgent to address this code. Delaying repairs can lead to less efficient fuel use, potentially more expensive issues, and failure to pass emissions tests in regions where they are required.
