SOURCE: code P1400 on a 1997 nissan maxima. help car wont pass inspection

P1400 on your vehicle is described as :Differential Pressure Feedback EGR Circuit Low Input You either need a new DPFE valve, or a new EGR valve. Both can be tested for functionality before replacing them both. EGR valve is more likely I think. Cleaning it may not improve its performance, but its worth a try. Also check the vacuum lines between the DPFE and EGR system. The EGR valve and DPFE are usually close together above the exhaust manifold/downpipe. you need service instructions to test these items, suggest you go to a garage really...

SOURCE: engie code P1537 how do I fix

That indicates that intake manifold runner control is stuck open. They will be open when vehicle off but will close at certain RPM's and are usually controlled by vacuum lines (red) that run to them. You'll have 2, when on front bank & one on rear if it's 3.8L. Actuators tend to get sticky & remain open. You can try freeing them up. Here's a link to a picture that will give you an idea of what to look for. ( http://rides.webshots.com/photo/1201999780011220610BGkBnV )

SOURCE: 2004 chevy malibu classic spark plug replacement

Search for the engine model ECOTec 2.2 rather then Malibu. It is very easy to replace the plugs, they are DEEP inside the engine so you will need a 6" socket extension for the spark plug socket. Needle nose pliers were required to retrieve the socket on the first plug. Don't push down hard on the plug, just enough to engage the nut. Full screen photo sequence is available at:

SOURCE: replacing spark plugs on a 2004 chevy malibu

2.2L Engine

  1. Observe the following service precautions:

    Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
  2. Turn the ignition OFF .
  3. Disconnect the Electronic Ignition (EI) module harness connector.
  4. Remove the spark plugs using a 5 / 8 inch spark plug socket.

To install:

WARNING Do not coat spark plug threads with anti-seize compound. If anti-seize compound is used and spark plugs are over-torqued, damage to the cylinder head threads may result.
  1. Inspect the gap on the new spark plugs, re-gap the plugs as required. The spark plug gap specification is 42 inch. (1.0 mm).
  2. Install the spark plugs and tighten to 15 ft. lbs. (20 Nm).
  3. Apply dielectric compound to the spark plug boots and make sure no corrosion is present.
  4. Install the ignition coil housing to cam cover and attachment bolts.
  5. Tighten the ignition coil housing bolts to 89 inch. lbs. (10 Nm).
  6. Connect the EI module harness connector. Push in until a click is heard and pull back to confirm a positive engagement.

Obd not working 2006 chevrolet malibu maxx unable to have car inspected


OBD2 works for getting codes causing check engine light.
Cannot communicate to NYS DMV to receive inspection.
It will pass inspection. No check engine lights or codes. Problem is communication with inspection machine.

I still do not know the answer to the problem.

P044 EVAPORATIVE EMISSION CONTROL SYSTEM LEAK / DETECTED SMALL LEAK ON A 2004 CHEVY AVEO


The most likely causes of this code are:
A Leak in the System
Faulty Purge Solenoid (This is the valve that lets the fumes into the engine)
Faulty or loose fuel cap
Faulty or Loose NVLD (This is the sensor that senses whether the system is working or not)
The first thing to try is re-installing your fuel cap as this can cause this code and is an easy fix. If you suspect the cap might be bad, then you might want to just replace it. You can also check for any loose or damaged hoses under your hood. They can cause this type of code.( p0440 ). good- day !

Wanted to know if 2004 chevy malibu classic has a battery hold down?


Hi


Glad to read your post, but I'm quite sure that every car out there that comes from the manufacturer has and must have a battery hold down to secure it, without the hold down the battery would just move around loosely, and could cause a fire or an electrical short. Nowadays most vehicle inspection stations will not pass your car without the battery hold down. So before you take ownership of a vehicle make sure the hold-down is in place.

How to reset a radio on a chevy malibu 2004? radio is now locked.


If your battery was replaced and the radio lost power then your anti thieft lock was activated. Check your oweners manual under radio and check for a 4 number pass word. Sometimes it is taped to the upper part of the glove box. If yopu do not have the CODE you will need to take the vehicle to the dealership or a repair center and they can give the vin number to a dealership and get the CODE.
