Standard Ignition LDP02 Evaporative Emissions System Leak Detection Pump

OE-Style Evaporative Leak Detection Pump

The Standard Ignition LDP02 is a direct-fit evaporative emissions system leak detection pump for vehicles that use engine vacuum to verify EVAP system integrity. Built as an OE replacement, it is engineered for accurate leak detection, stable switch readings, and a precise electrical connection to the engine wiring harness.

Compatible With select Dodge Ram 1500 Van, Ram 2500 Van, Ram 3500 Van, Chrysler Prowler, Plymouth Prowler, Chrysler Sebring, Dodge Avenger, and Dodge B1500/B2500/B3500 applications, the Standard Ignition LDP02 supports factory-style fitment and function.

• Direct-fit OE replacement for evaporative emissions leak detection
• Uses engine vacuum to help detect proper EVAP system leaks
• Precision-calibrated diaphragm and spring for accurate switch voltage readings
• OE-quality connector and terminals for exact harness fit and conductivity
• High-temperature OE-style plastic housing for underhood durability
• Standard Ignition LDP02 cross-references Dorman OE Solutions 310-204 for the same application

Detailed Product Overview

This evaporative emissions system leak detection pump is built around the attributes that matter for service replacement: one female connector, three blade terminals, and three hose connections sized for 1/4 in. and 5/8 in. lines. The housing, connector, and terminal design are intended to match OE dimensions so the pump seats correctly and maintains consistent electrical contact. For drivers addressing EVAP faults on Chrysler Sebring or Dodge Avenger platforms, the LDP02 provides a factory-style repair path.

Common EVAP Issues It Can Address

• Check engine light related to evaporative emissions leak detection
• Fault codes tied to EVAP system pressure or vacuum testing
• Intermittent switch signal caused by worn internal diaphragm components
• Poor electrical connection at the pump connector or terminals
• Fitment problems from damaged or heat-aged OE-style plastic housings

Installation Notes and Tips

Verify hose sizes and connector style before installation, especially on Dodge Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van applications. Inspect EVAP hoses for cracks, soft spots, or collapsed sections before connecting the new pump, and confirm the wiring harness terminals are clean and fully seated. After installation, clear diagnostic trouble codes and perform the appropriate EVAP system test to confirm proper operation.

Quality Assurance

Standard Ignition builds this pump as an OE-quality replacement with calibrated internal components, OE-style electrical interfaces, and a high-temperature housing for reliable service in demanding underhood conditions. The LDP02 is engineered to restore factory-style evaporative leak detection performance on the listed applications.
