TPS Throttle Position Sensor for Nissan Infiniti 22620-6P005 22620- 5E400

22620-6P005 Throttle Position Sensor 22620- 5E400 for Nissan / Infiniti

The sensor operates as a potentiometer that detects the throttle blade angle. It typically utilizes a three-wire configuration: a 5-volt reference from the Powertrain Control Module (PCM), a ground from the PCM, and a signal return from the TPS to the PCM. The signal voltage varies proportionally with throttle opening, providing the ECU with continuous, real-time data for fuel injection and ignition timing adjustments.

The Throttle Position Sensor 22620-6P005 is an Original Equipment (OE) number for Nissan and Infiniti vehicles. It is identified by the following OE reference numbers and cross-references:

Common Reference Designations:

• Throttle Position Sensor (TPS)

• Switch

• Sensor, Throttle

• Accelerator Throttle Position Sensor

The Throttle Position Sensor 22620-6P005 is designed for compatibility with Nissan and Infiniti vehicles.

Important Compatibility Notes:

• This sensor is an Original Equipment (OE) number for Nissan and Infiniti vehicles

• Compatible with both manual and automatic transmission variants

• Always cross-check the OE reference number against the number found on your current unit to ensure proper fitment

• The sensor is mounted on the throttle body and provides the ECU with throttle position information

A failing or malfunctioning Throttle Position Sensor can produce a range of drivability issues. Below are the most common symptoms to watch for:

One of the earliest indicators of a TPS problem is the illumination of the Malfunction Indicator Lamp (Check Engine Light) on the dashboard. A faulty TPS will almost certainly trigger the Check Engine Light and store a diagnostic trouble code (DTC). Common diagnostic trouble codes (DTCs) associated with TPS failure include:

• P0120 – Throttle/Pedal Position Sensor/Switch "A" Circuit Malfunction

• P0121 – Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance

• P0122 – Throttle/Pedal Position Sensor/Switch "A" Circuit Low Input

• P0123 – Throttle/Pedal Position Sensor/Switch "A" Circuit High Input

The most common symptom of a faulty TPS is hesitation or a sudden surge in acceleration. The vehicle may jerk or stumble because the malfunctioning sensor fails to send proper throttle position data, causing an imbalance in the air-fuel mixture needed for smooth acceleration.

A faulty TPS can cause the engine idle speed to fluctuate unpredictably. The idle may be too high or too low, leading to rough idling or "hunting" RPMs. At closed throttle, the ECU relies heavily on the TPS to maintain idle speed.

Since the ECU relies on throttle position data to determine the correct air-fuel ratio, a defective sensor may cause incorrect fuel trims, leading to poor fuel consumption.

The engine may stall unexpectedly—particularly when stopping or at idle—as the ECU receives incorrect throttle position signals and fails to maintain proper air or fuel delivery.

The throttle may become unresponsive or delayed when the accelerator pedal is pressed. This occurs because the ECU is not receiving accurate position data to adjust fuel delivery and ignition timing accordingly.

The vehicle may experience surging or "bucking" while maintaining a steady speed or under moderate load, as the ECU receives fluctuating throttle position signals.

A malfunctioning TPS can cause harsh, delayed, or erratic shifting in automatic transmissions. The transmission control module (TCM) uses TPS data as one of the inputs for shift timing.

• Wear and tear – Internal potentiometer tracks wear over time due to repeated throttle movements

• Carbon buildup – Excessive carbon deposits on the throttle body can cause the sensor to stick

• Physical damage – Impact or mechanical stress can damage the sensor housing or internal components

• Open or short circuit – Wiring issues in the sensor circuit

• Moisture ingress – Liquid intrusion can cause corrosion and electrical shorts

When sourcing or purchasing the Throttle Position Sensor 22620-6P005, consider the following factors to ensure optimal performance and compatibility:

Always confirm that the part number on your existing sensor matches 22620-6P005 or 226206P005. Related numbers include 22620-5E400. Cross-check the OE reference number against the number found on your current unit before purchasing. The part number will appear on the component itself.

Ensure the sensor is compatible with your specific vehicle make, model, year, engine size, and transmission type. This sensor is primarily designed for Nissan Altima (1996–1997), Nissan Pulsar (2003), Infiniti Q45 (1997–2001), and Nissan Cima Y33 (1996–1998). Selecting the wrong sensor can lead to poor engine response or persistent check engine light issues.

Verify that you are purchasing a 3-wire potentiometer-type sensor. This sensor requires a 5-volt reference from the PCM, a ground connection, and provides a signal return to the PCM.

Look for sensors constructed with durable automotive-grade materials. High-quality sensors are built to the same dimensional and material standards as the original part they replace, ensuring reliable performance and a long service life.

Prioritize products that meet or exceed OEM standards. Parts that match the same OE specification used by the vehicle manufacturer ensure proper fit and function.

When sourcing from suppliers, evaluate their quality assurance processes and production capacity. Look for evidence of:

• Strict quality control standards meeting OEM specifications

• 100% factory testing

• Full manufacturer traceability

• Warranty coverage (some suppliers offer 3-year warranties)

The sensor is mounted on the throttle body. During installation, ensure that:

• The sensor is properly aligned with the throttle shaft

• Mounting screws are tightened to the correct torque specification

• The connector is securely fastened

• Sensor wires are not routed over sharp edges

• Proper clearance is maintained from ignition HT leads, coil leads, and other sources of electrical interference

After installation, it is recommended to verify the sensor operation using a diagnostic scan tool. Check that the throttle position readings are smooth and consistent throughout the full range of throttle movement and that the warning light is no longer illuminated.

Consider products that come with a reasonable return policy. Some suppliers offer 90-day free returns. A warranty can provide assurance of product quality and reliability.
