Why does my 2000 Nissan Quest emits humming sound when engine run


Most likely, that is the sound of the FUEL PUMP. If the car is running well, don't worry about it. Try changing your fuel filter to see if that helps (usually does).
If you have trouble with fuel delivery at high speeds or under load, suspect that your fuel pump is about to fail.

Dodge caravan 2001 blowing burning power steering fluid.


I can answer some of your questions without being there in person.
The smell inside the van is from fresh air entering the venting system. Not sure why you don't get it from all vents. The fresh air intake is in front of the windshield and will pick up any smells from the engine compartment.
Loosing the serpentine belt would not necessarily cause you to loose ps fluid, but having a leak could drain the pump and damage the bearings in the pump, causing the pump pulley to drag on the belt.
The ps pump could be in the final stage of failing.
And the shaft seal in the pump could be leaking fluid onto the engine and exhaust.

Only code p0734 2001 caravan


Hi there:
This code means that the transmission is slipping in high gear and the TCM (TRansmission Control Mocule) logic thinks it has incorrect ratio since it monitors input and output speed. Keep in mind that TCM uses input from the input speed sensor and output speed sensor to determine gear ratios. The TCM then compares the known gear ratio to the calculated gear ratio for the current range.


Check HERE test procedure.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa, have a nice day.

Took our 2001 Caravan SE to local mechanic because rear wiper quit working. They diagosed proble as faulty PCM. Thought they were doing us a favour by putting in a used one from a 2002 that they thought...


i dont see why they would diag the pcm for the rear wiper, power from fuse to switch to wiper!! no pcm in between this operation. I would have had this fixed in a hour. Have mechanic pay for the bill to get it running. It was running fine when you took it there and only the rear wiper didnt work and now you are out of a vehicle and a tow bill at a hourly dealer cost. Best of luck to you 300.00 later.

A/c squeal


Have the belt tensioner checked, it might have a weak spring keeping the belt from having the right tension on the pulleys.

I have a 2001 Dodge Grand Caravan Sport w/ 3.3l flex fuel and the van is idling odd. I have changed the MAP sensor, the IAC sensor, and the spark plugs and wires, and no change.


Could be that your coil pack has gone bad. This is not a cheap piece though, so you will want to be sure.

Does it run fine when up off of idle, or does it also seem to be missing as you drive down the road.

I hear a high pitched tone once the engine gets warmed up and it louder outside of the van 2003 Dodge Caravan


Its most probably the water pump which has become dry. Greasing it should solve this high pitched noise. If it still appears, them check all the pulleys to which the belts are attached. Any one of them might require greasing......sodeep

1997 Civic LX A constant mid-high pitched humming noise?


Have you had the water pump replaced yet? Could possibly be the water pump making noise because it's about to go.
