Standard Ignition TH133 Throttle Position Sensor

Throttle Position Sensor for Nissan Applications

Standard Ignition TH133 is a throttle position sensor for select Nissan fuel-injected applications. It monitors throttle angle and sends the signal needed for accurate engine response, idle control, and fuel delivery. This TH133 throttle position sensor is built with a female 2-pin plug-in connector, 6 male blade terminals, and a direct-fit electrical layout for service replacement.

Key Features

• Throttle position sensor for emission control and engine management systems
• Female connector with 2 plug-in terminals for straightforward harness connection
• 6 male blade terminals for the specified application interface
• Direct replacement part number TH133 for service matching
• Cross-references Standard Ignition TH133 and OE-style applications using 2-19293 or 2262071L00

Detailed Description

Standard Ignition TH133 is a throttle position sensor used to report throttle movement to the engine control system. On Nissan Pathfinder, Nissan Pickup, and Nissan D21 applications, the sensor helps the ECU interpret throttle opening so the vehicle can manage acceleration, idle behavior, and fuel control more accurately. If you are replacing a worn Nissan Pathfinder throttle position sensor or sourcing a Nissan D21 TPS replacement, TH133 provides the correct connector and terminal configuration for the listed vehicles.

This part cross-references 2-19293 and 2262071L00 for the same application. The TH133 part number is also useful when matching an existing Standard Ignition replacement during diagnosis or repair.

Vehicle Fitment

• Fits 1990-1995 Nissan Pathfinder, N/A
• Fits 1995 Nissan Pickup, N/A
• Fits 1990-1994 Nissan D21, N/A

What It Helps Fix

• Throttle signal errors that affect acceleration response
• Unstable or incorrect idle behavior caused by a worn sensor
• Fuel delivery issues related to inaccurate throttle input
• Check engine light conditions tied to throttle position feedback
• Driveability complaints on Nissan Pathfinder, Pickup, or D21 models

Installation Notes and Tips

Verify connector style, terminal count, and mounting alignment before installation. Compare the original sensor position and electrical connector to TH133 before removal, and inspect the throttle body and harness for wear, corrosion, or damaged terminals. After installation, clear any stored codes and confirm throttle signal operation with a scan tool or multimeter.

Quality Assurance

Standard Ignition is a recognized aftermarket source for engine management and emission control components. TH133 is built to match the listed application requirements for Nissan Pathfinder, Nissan Pickup, and Nissan D21 service replacement.
