P2135 2005 Nissan Maxima Code - Throttle Position Sensor Circuit Range/Performance

Quick Answer

The P2135 diagnostic trouble code (DTC) in a 2005 Nissan Maxima indicates a problem with the Throttle Position Sensor (TPS) circuit, specifically related to its range or performance. Common causes include Faulty TPS: The TPS itself may be worn out, damaged, or incorrectly calibrated, causing it to send inaccurate signals to the ECM, Wiring issues: Damaged wiring harness, loose connections, or corroded terminals can disrupt the TPS circuit and trigger the P2135 code, ECM malfunction: A malfunctioning engine control module may fail to interpret the TPS signals correctly, leading to performance issues. 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 2005 Nissan Maxima Description

The P2135 diagnostic trouble code (DTC) in a 2005 Nissan Maxima indicates a problem with the Throttle Position Sensor (TPS) circuit, specifically related to its range or performance. The TPS is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending signals to the engine control module (ECM) to adjust the throttle opening accordingly. When the ECM detects that the TPS circuit's signal is out of the expected range or not performing within specified parameters, it triggers the P2135 code.

Common Causes of P2135 2005 Nissan Maxima

  1. Faulty TPS: The TPS itself may be worn out, damaged, or incorrectly calibrated, causing it to send inaccurate signals to the ECM.
  2. Wiring issues: Damaged wiring harness, loose connections, or corroded terminals can disrupt the TPS circuit and trigger the P2135 code.
  3. ECM malfunction: A malfunctioning engine control module may fail to interpret the TPS signals correctly, leading to performance issues.
  4. Throttle body problems: Issues with the throttle body, such as carbon buildup or mechanical wear, can affect the TPS operation and trigger the code.
  5. Environmental factors: Extreme temperatures, moisture, or contaminants can impact the TPS circuit's performance, causing intermittent faults.

Symptoms of P2135 2005 Nissan Maxima

  1. Erratic throttle response: The vehicle may exhibit unpredictable acceleration or deceleration, making it challenging to maintain a steady speed.
  2. Poor acceleration: The engine may struggle to deliver power efficiently, resulting in sluggish performance when accelerating.
  3. Stalling or rough idling: The engine may stall unexpectedly or run roughly at idle, indicating a disruption in the throttle control system.
  4. Engine misfires: The TPS issue can lead to misfires, causing the engine to run unevenly or produce noticeable vibrations.
  5. Limp mode activation: In severe cases, the vehicle may enter a limp mode to protect the engine from further damage, limiting its performance.

How to Fix P2135 2005 Nissan Maxima

  1. Diagnostic scan: Begin by using a diagnostic scan tool to retrieve the trouble codes and identify the specific TPS-related issue.
  2. TPS inspection: Inspect the throttle position sensor for any signs of wear, damage, or misalignment. Test the sensor's voltage output using a multimeter.
  3. Wiring check: Inspect the wiring harness connected to the TPS for any visible damage, corrosion, or loose connections. Repair or replace any faulty wiring.
  4. TPS replacement: If the TPS is found to be faulty, replace it with a new, OEM-quality sensor. Ensure proper installation and calibration according to manufacturer specifications.
  5. ECM reprogramming: In some cases, reprogramming the engine control module may be necessary to recalibrate the TPS and clear the fault codes.

Cost to Fix P2135 2005 Nissan Maxima

The typical repair costs for addressing a P2135 code in a 2005 Nissan Maxima can vary depending on the specific cause of the issue and the parts/labour rates in your area. On average, replacing a throttle position sensor can cost between $100 and $300, including parts and labour. However, additional diagnostic time and potential repairs for wiring issues, ECM reprogramming, or throttle body problems may increase the total cost. It's recommended to consult with a trusted mechanic or auto repair shop to get an accurate estimate based on your vehicle's condition and location. Keep in mind that labour rates can range from $80 to $150 per hour, with variations based on the service provider and geographical area.

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
