Xotic Performance Throttle Position Sensor for Dodge Ram 5.9L Cummins (1998.5–2007) — Direct-Fit, OEM-Style Replacement

High-precision throttle position sensor built to replace factory units on Dodge Ram 5.9L Cummins rigs, restoring responsive throttle input and reliable engine signaling.

When a faulty throttle position sensor causes hesitation, erratic idle, or check-engine codes on 1998.5–2007 Dodge Ram 2500/3500 Cummins 5.9L (and 1998.5–2002 5.9L gas Ram), a robust direct-fit replacement restores consistent throttle readings and drivability. The Xotic Performance TPS APPS unit is engineered to match OEM connections, bracketry, and electrical behavior while resisting heat and vibration common in diesel engine compartments.

How will this sensor resolve throttle-related drivability issues?

This TPS/APPS is calibrated to reproduce OEM voltage and signal characteristics so the engine computer receives accurate throttle position data. Replacing a worn or damaged sensor eliminates noisy or intermittent signals that trigger limp modes or throttle hesitation.

• Replaces failing sensors that cause codes P2121, P0121, P0122, P0123
• Prevents sudden speed drop-offs and unstable idle by stabilizing signal output
• Factory-style electrical connector and mounting reduce installation adjustments

Is this a direct fit for my Dodge Ram 5.9L?

Yes — the part is designed as a direct factory replacement for multiple OE references and fits specific model years without modification. Always confirm vehicle year, engine type, and original part numbers before ordering to ensure correct fitment.

• Fits 1998.5–2007 Dodge Ram 2500 & 3500 Cummins Diesel 5.9L
• Also fits 1998.5–2002 Dodge Ram 2500 & 3500 Gas 5.9L models
• Compatible with OEM numbers: 53031576, 53031576AD, 3970085, AP63427, 53031575, 53031575AH, 3970084, AP63428, 56028184A

What makes the Xotic Performance unit durable and reliable?

The sensor uses a flexible circuit board and rugged components designed to withstand the heat, vibration, and electrical stresses found under the hood of heavy trucks. Every unit is inspected and tested at the end of production to ensure accurate output and long-term reliability.

• Premium materials resist heat and vibration for extended service life
• OE-style brackets, hold-downs, hardware and spacers included for secure mounting
• End-of-line testing performed to verify signal stability before shipping

How difficult is installation and what should I expect?

Installation follows OEM mounting points and electrical connectors, so professional or experienced DIYers can swap the sensor with basic hand tools. No special programming is usually required, but clearing codes or a quick throttle relearn via the vehicle’s procedure may be needed.

• Direct-fit design minimizes modification and installation time
• Includes factory-style hardware to match original fitment
• Check engine reset or relearn may be necessary after replacement

Who is this for: The Xotic Performance TPS APPS Throttle Position Sensor is aimed at Dodge Ram owners and professional technicians who need a dependable, OEM-standard replacement for failing TPS/APPS units on 5.9L Cummins and compatible 5.9L gas models. It’s ideal for anyone troubleshooting throttle-related codes, intermittent throttle response, or unstable idle who wants a proven, test-verified swap that restores correct sensor readings and vehicle behavior.
