P0222 2005 Nissan Maxima Code - Throttle Position Sensor/Switch 2 Circuit Low Input
Quick Answer
The P0222 diagnostic trouble code (DTC) for a 2005 Nissan Maxima refers to the Throttle Position Sensor/Switch 2 Circuit Low Input. Common causes include Faulty TPS/Switch 2: The sensor itself may be malfunctioning and sending incorrect signals to the ECM, Damaged wiring or connectors: Corrosion, fraying, or loose connections in the wiring harness can disrupt the signal between the TPS and ECM, Malfunctioning ECM: A problem with the engine control module can interfere with the TPS readings and cause the low input code. 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 P0222 2005 Nissan Maxima Description
The P0222 diagnostic trouble code (DTC) for a 2005 Nissan Maxima refers to the Throttle Position Sensor/Switch 2 Circuit Low Input. This code indicates that there is an issue with the electrical circuit associated with the throttle position sensor (TPS) or throttle position switch in the vehicle. The TPS is a crucial component that monitors the position of the throttle valve, which controls the amount of air entering the engine. It provides feedback to the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance.
Common Causes of P0222 2005 Nissan Maxima
- Faulty TPS/Switch 2: The sensor itself may be malfunctioning and sending incorrect signals to the ECM.
- Damaged wiring or connectors: Corrosion, fraying, or loose connections in the wiring harness can disrupt the signal between the TPS and ECM.
- Malfunctioning ECM: A problem with the engine control module can interfere with the TPS readings and cause the low input code.
- Throttle body issues: Problems with the throttle body, such as carbon buildup or mechanical issues, can affect the TPS functionality.
Symptoms of P0222 2005 Nissan Maxima
- Decreased acceleration: The vehicle may struggle to accelerate smoothly or respond sluggishly to throttle inputs.
- Rough idling: The engine may idle erratically or stall frequently when at a stop.
- Hesitation: There may be a noticeable delay or hesitation when pressing the gas pedal.
- Poor fuel efficiency: The vehicle may consume more fuel than usual due to improper throttle position readings.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard as a result of this issue.
How to Fix P0222 2005 Nissan Maxima
- Diagnose the issue: Use a diagnostic scan tool to retrieve the fault code and perform a thorough inspection of the TPS, wiring, and connectors.
- Replace TPS/Switch 2: If the sensor is faulty, replace it with a new one following the manufacturer's guidelines.
- Repair wiring/connectors: Repair or replace any damaged wiring or connectors to ensure proper electrical connections.
- Check ECM: Verify the ECM's functionality and replace it if necessary.
- Clear codes and test drive: Clear the fault codes from the ECM, reset the system, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0222 2005 Nissan Maxima
The cost of repairing a Throttle Position Sensor/Switch 2 Circuit Low Input issue on a 2005 Nissan Maxima can vary depending on the extent of the damage and the specific parts needed for replacement. On average, the cost of replacing a TPS can range from $100 to $300, including parts and labor. Additional costs may apply if there are wiring or ECM issues that need to be addressed. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on your vehicle's specific condition. Keep in mind that labor rates can vary between different locations and service providers.
