How do I fix the cruise control on my 2009 Aveo 5? Just stopped working one day.

Could be a fuse, band switch or a vacuum leak. Check the vacuum system and hoses could just be one of the vacuum hose end are split, loose or hardened causing a leak.

5 speeds No power after put into gear

sounds like a vacuum leak, older vehicles used vacuum 2 shift gears, the biggest leak you could have would be the EGR valve and any vacuum leak could cause the engine 2 die

2173 error code on 2006 dodge magnum 3.5 liter HO 6 cylinder?

A large vacuum leak is most likely the cause of this DTC.
Inspect the Intake Manifold and Throttle body for leaks and cracks.
Inspect the Power Brake Booster for any vacuum leaks.
Inspect the PCV system for proper operation or any vacuum leaks.
Inspect the MAP Sensor for proper installation.

Heat does not out on front dashbord and doesn't work on 5 at al

Check for vacuum leak under dash to heater control vacuum harness, or anything connected to it. Commonly disturbed by stereo installation Could also cause a rough idle. Leak could also be found between manifold and vacuum junction to heater control under hood.

How do i replace the natural vacuum leak detection pump on a 2005 dodge dakota?

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.



Have a nice day (remember rated this help).

you have a vacuum leak. Check the vacuum reservoir for a leak.

You can spray short bursts of starting fluid on the vacuum lines to find a leak. When engine revs, that's the leak. Be careful.

Vacuum Reservoir Tank and Bracket Removal
  1. NOTE: The A/C vacuum reservoir tank and bracket (19A566) is located either on or beneath the RH front fender splash shield (16102) .
    If the A/C vacuum reservoir tank and bracket is visible from above in the engine compartment, perform Steps 2 through 4. If the A/C vacuum reservoir tank and bracket is not visible in the engine compartment, perform Steps 5 through 8.
  1. Remove the screws and the A/C vacuum reservoir tank and bracket. 1b32ebf.gif
