Keep the evaporative emissions system sealing and self-testing correctly with the Standard Ignition Evaporative Emissions System Leak Detection Pump (LDP03). This leak detection pump uses engine vacuum to check the EVAP system for leaks and report the results to the engine control module. It installs as a direct-fit replacement for the 2001 Jeep Cherokee — see the Buyer's Guide tab for engine details.

  • Direct-fit OE replacement: works with engine vacuum to accurately detect evaporative leaks.
  • High-temperature OE-style plastic housing: supports precise fit and performance under demanding conditions.
  • OE-quality connector and terminals: designed for an exact fit and strong conductivity to the engine wiring harness.
  • Precision-calibrated diaphragm and spring: open and close properly to provide accurate voltage readings to the switch.

If a failed leak detection pump is the source of an EVAP-related trouble code or illuminated check engine light, this unit replaces it; diagnose the cause before replacing so any other EVAP faults are addressed too.
