SOURCE: how do i replace the natural vacuum leak detection

Vehicles equipped with NGC engine control modules use an NVLD pump and system. Vehicles equipped with JTEC engine control modules use a leak detection pump. Refer to Leak Detection Pump (LDP) for additional information.
The Natural Vacuum Leak Detection (NVLD) system is the next generation evaporative leak detection system that will first be used on vehicles equipped with the Next Generation Controller (NGC). This new system replaces the leak detection pump as the method of evaporative system leak detection. This is to detect a leak equivalent to a 0.020 (0.5 mm) hole. This system has the capability to detect holes of this size very dependably.


Removal & Installation

  1. Raise and support vehicle.
  2. Remove left-rear tire.
  3. Remove plastic shield (4) in front of left-rear tire. Access to both the EVAP canister (1) and NVLD pump (6) is from the area in front of the removed tire.
  4. Disconnect electrical connector at NVLD pump.
  5. Remove vapor line at NVLD pump. Pry outward on tab (3) and rotate pump (6) clockwise about 70 for removal.
  6. Remove NVLD pump O-ring (5) from EVAP canister (1).
To Install:
  1. Install new NVLD pump O-ring (5) to EVAP canister (1).
  2. Position NVLD pump (6) into EVAP canister (1).
  3. Rotate pump (6) until tab aligns with notch in EVAP canister (1).
  4. Carefully install vapor/vacuum lines to NVLD pump.
    WARNING The vapor/vacuum lines and hoses must be firmly connected. Check the vapor/vacuum lines at the NVLD pump, filter and EVAP canister purge solenoid for damage or leaks. If a leak is present, a Diagnostic Trouble Code (DTC) may be set.
  5. Connect electrical connector to pump.
  6. Install plastic shield in front of left-rear tire.
  7. Install left-rear tire.
