P2135 2004 Nissan Maxima Code - Throttle Position Sensor Circuit Range/Performance

Quick Answer

The P2135 diagnostic trouble code (DTC) in a 2004 Nissan Maxima indicates a problem with the throttle position sensor (TPS) circuit. Common causes include Faulty TPS: The TPS itself may be malfunctioning, providing incorrect voltage readings to the ECM, Wiring or connector issues: Damaged wiring or connectors in the TPS circuit can disrupt the signal transmission, ECM malfunction: A faulty ECM can misinterpret TPS signals, triggering the P2135 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 P2135 2004 Nissan Maxima Description

The P2135 diagnostic trouble code (DTC) in a 2004 Nissan Maxima indicates a problem with the throttle position sensor (TPS) circuit. The TPS is a crucial component that monitors the position of the throttle valve and sends signals to the engine control module (ECM) to adjust fuel delivery and ignition timing. When the ECM detects that the TPS circuit's voltage readings are outside the expected range, it triggers the P2135 code.

Common Causes of P2135 2004 Nissan Maxima

  1. Faulty TPS: The TPS itself may be malfunctioning, providing incorrect voltage readings to the ECM.
  2. Wiring or connector issues: Damaged wiring or connectors in the TPS circuit can disrupt the signal transmission.
  3. ECM malfunction: A faulty ECM can misinterpret TPS signals, triggering the P2135 code.
  4. Throttle body problems: Issues with the throttle body, such as carbon buildup or mechanical failures, can affect TPS readings.

Symptoms of P2135 2004 Nissan Maxima

  1. Poor acceleration: The vehicle may struggle to accelerate smoothly or respond slowly to throttle input.
  2. Rough idling: The engine may idle erratically or experience fluctuations in RPM.
  3. Stalling: The engine may stall unexpectedly, especially when coming to a stop or at low speeds.
  4. Hesitation: The vehicle may hesitate or jerk during acceleration, making driving uncomfortable.
  5. Engine misfires: Misfires can occur due to incorrect fuel delivery and ignition timing, leading to rough running and potential damage to the engine.

How to Fix P2135 2004 Nissan Maxima

  1. Diagnose the issue: Use a scan tool to retrieve the trouble codes and perform a thorough inspection of the TPS circuit, wiring, and connectors.
  2. Replace the TPS: If the TPS is faulty, replace it with a new one following the manufacturer's guidelines.
  3. Repair wiring or connectors: Repair or replace any damaged wiring or connectors in the TPS circuit to ensure proper signal transmission.
  4. Check ECM functionality: Verify the ECM's functionality and reprogram it if necessary to address any issues with TPS signal interpretation.
  5. Test drive and recheck: After repairs, test drive the vehicle to confirm that the symptoms have been resolved, and recheck for any remaining trouble codes.

Cost to Fix P2135 2004 Nissan Maxima

The typical repair costs for addressing a P2135 code in a 2004 Nissan Maxima can range from $150 to $400, including parts and labor. However, specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.

When is the Code Detected?

The code P2135 is set when the and incorrect voltage is sent to the Engine Control Module (ECM) compared with the signals from Throttle Position (TP) sensor 1 and Throttle Position (TP) sensor 2
