There is a vacuum pump on these since this engine does not develop any.It is driven by the fan belt.On the left front of engine i believe. Notorious for failure. Place a vacuum gage in /on suction port, should get a mimum of 18 in. hg. If ok check for broke hoses ,plastic lines,and fittings.Hope this helps. Please rate me.Thanks.

Engine making hissing sound


Mix a bit of soap and water and spray near the sound to determine from where the sound is coming, and post more information. If it's a gas car, try not to spray much water on wires like spark plugs or coils. Post information like make and model of car. Engine size, turbo or not, diesel or gas? Not much to go on here. Could be a small vacuum leak or a busted manifold, a bad intercooler, who knows with this bit of info?

What does the fuel pressure have to be on a 1997 dodge intrepid


  1. Without vacuum applied to the regulator, the 3.3L engine fuel system operates at 55 psi (379 kPa). With the engine idling and the manifold vacuum applied to the regulator, the system operates at approximately 46 psi (317 kPa).
  2. Without vacuum applied to the regulator, the 3.5L engine fuel system operates at 48 psi (331 kPa). With the engine idling and the manifold vacuum applied to the regulator, the system operates at approximately 39 psi (269 kPa).
  3. The fuel system pressure varies with the different amounts of manifold vacuum applied to the regulator. If the pressure is NOT correct, record the pressure and remove the gauge.

1997 expedition vent chages air flow from panel to defrost when under load


Suspect a problem with a check valve in the vacuum lines somewhere. When you ask for "power", the manifold vacuum dives. This is affecting your ventilation. It is not supposed to happen as you know.

Many ventilation controls use engine intake manifold vacuum as power to move miniature air valve actualtors. Actuators may be balanced by springs. Springs pull one way, vacuum (controlled by the dash knobs) pulls against springs. When the throttle is opened (accelerator pushed hard) the manifold vacuum drops.

When the vacuum drops, then the spring would be strongest and pull the control valve over. When the throttle goes back to normal--- vacuum is back up, and air flow changes again.

There should be a check valve in (one-way valve) in the system so that the vacuum is held during periods of acceleration. If this valve is stuck open by wear or contamination, everytime you ask for power you would lose the vacuum in the controls.

A full diagram of the system is needed to trace this which I do not have.

This should give you a place to start or at least know what you are hearing if you have someone troubleshoot this.

Check engine light on - P0400 malfunction


Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system recirculates exhaust gas into the intake manifold (9424). This lowers combustion temperatures and reduces the formation of oxides of nitrogen (NOX). The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the powertrain control module (PCM) (12A650). The EGR valve (EGR valve) (9D475) is vacuum actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. EGR operation stops when the engine temperature is cold, to improve driveability. The PCM controls the EGR solenoid vacuum valve (9D474). When energized the intake manifold vacuum outlet fitting and cap (9A474) allows exhaust gas to be circulated in the engine to be burned.

Well, the 'T' in your model number is the answer; Turbo.

Non-turbo engines produce vacuum nearly all the way through their operating range since the engine functions as an air pump on the intake cycle to obtain the oxygen required for combustion.

The turbo, which is probably kicking in at around that 1800 revs, produces an overpressure so the engine can accommodate more fuel, be it diesel or gasoline.

Your engine and the turbocompressor, are doing exactly what they were designed for and your system (which I have personally used) not only doesn't do anything useful, is also causing a loss of your overpressure.
