• Fits 1998-2002 Dodge Ram 3500, Full Bellcrank Assembly
• Female connector with plug-in design
• 6-pin male terminals
• Flexible polyimide film or ceramic-based circuit construction for dimensional stability
• Noble metal contact materials for low resistance and extended service life
• Integral rotor bearings and return springs for straightforward installation

Detailed Product Overview

Standard Ignition TH383 is engineered as an OE-style throttle position sensor for Dodge Ram 2500 and Dodge Ram 3500 trucks from 1998 through 2002 with a full bellcrank assembly. The sensor is built with printed circuits on stable substrates to help prevent electrical drift, while the fixed output design supports the original calibration strategy rather than an adjustable consolidated layout. The TH383 part number is also referenced in cross-application listings for service replacement use.

This part cross-references Standard Motor Products (e.g., TPS346, EC3339) for the same application.

Common Symptoms It Can Address

• Erratic throttle signal readings
• Delayed or inconsistent throttle response
• Check engine light related to throttle position input
• Rough idle or hesitation during acceleration
• Driveability issues caused by unstable sensor output

Installation Notes

Verify connector style, terminal count, and throttle linkage configuration before installation. This TH383 sensor uses a female plug-in connector with 6 male pin terminals, so matching the harness and mounting style is important for proper fitment on the Ram 2500 and Ram 3500 full bellcrank assembly. Confirm throttle linkage alignment and follow the vehicle service procedure for sensor setup and calibration checks after installation.

Quality Assurance

Standard Ignition manufactures emission control components with process control from component materials through finished product testing. Each TH383 throttle position sensor is end-of-line tested with extensive voltage data validation to support consistent output and dependable operation.
