Here is a list of typical error codes for Nissan Quest V41 (1998-2002) and possible solutions:

1. P0101 – Mass Airflow Sensor (MAF) Error

Description: Issue with the MAF sensor, which measures the amount of air entering the engine.
Troubleshooting:

• Check and clean the MAF sensor.
• Replace the damaged sensor if cleaning doesn't help.
• Inspect the intake system for air leaks.

2. P0171/P0174 – Lean Fuel Mixture (Bank 1 and Bank 2)

Description: The air-fuel mixture is too lean, which can cause a loss of engine power.
Troubleshooting:

• Check for vacuum or intake system leaks.
• Clean or replace oxygen sensors (O2 sensors).
• Inspect fuel injectors and fuel delivery system.

3. P0300 – Multiple Misfires Detected

Description: Misfires are occurring in multiple cylinders, causing rough engine operation.
Troubleshooting:

• Inspect and replace spark plugs as needed.
• Check ignition coils and wiring.
• Examine the fuel delivery system and engine compression.

4. P0420 – Catalyst System Efficiency Below Threshold (Bank 1)

Description: The catalytic converter is not operating efficiently, leading to increased emissions.
Troubleshooting:

• Inspect and, if necessary, replace the catalytic converter.
• Check oxygen sensors (before and after the catalytic converter).
• Clean the exhaust system from possible obstructions.

5. P0455 – Large Evaporative Emission (EVAP) Leak

Description: The EVAP system has detected a large fuel vapor leak.
Troubleshooting:

• Ensure the gas cap is tightly closed.
• Check for leaks in the EVAP hoses.
• Inspect and replace the EVAP purge valve.

6. P0110 – Intake Air Temperature Sensor Error

Description: A faulty intake air temperature sensor affects the air-fuel mixture.
Troubleshooting:

• Inspect wiring and sensor connectors.
• Replace the sensor if it is defective.

7. P0130 – Oxygen Sensor Error (Bank 1, Sensor 1)

Description: Problems with the first oxygen sensor in the first bank, affecting the fuel mixture.
Troubleshooting:

• Check the sensor wiring.
• Clean or replace the defective oxygen sensor.

8. P0500 – Vehicle Speed Sensor (VSS) Error

Description: A malfunctioning speed sensor can affect the speedometer and ABS system.
Troubleshooting:

• Inspect the speed sensor on the transmission.
• Check the sensor wiring and connectors.
• Replace the sensor if faulty.

9. P0705 – Transmission Range Sensor Error

Description: Malfunction in the transmission range sensor may lead to improper gear shifting.
Troubleshooting:

• Inspect the wiring and connections of the sensor.
• Replace the transmission range sensor if defective.

10. P0115 – Engine Coolant Temperature Sensor Error

Description: Problem with the coolant temperature sensor, which can cause engine overheating.
Troubleshooting:

• Check the coolant level.
• Inspect the sensor for damage or faults.
• Replace the sensor if the issue persists.
