SOURCE: remote start will not let car start

The remote start won't keep the car from starting.

If you have a check engine light on currently, that will not allow the remote start to function at all.

SOURCE: how do you clean the egr valve on 99 pontiac montana

You would need to remove it and look into the passage that is covered in black soot. there is usually a little poppet that moves up and down to allow the exhaust gas to pass thru it, some are vacuum operated and some are electric. you can push the poppet open and scrape out the carbon with a little screw driver, generally they dont get all that pluged up on newer cars. I looked at a picture of yours at auto zone.com It appears yours is electrically actuated. If either the electric actuator or the position feedback in the valve are bad you would need to replace it. You could attempt to clean it and move the poppet up and down it could just be stuck

Either code 4000 or 1400 on 2002 ford ranger 4.0 ltr v6. the right code should equate to the egr valve. I have replaced the egr valve but check engine light comes on again after reset showing same code.


code p1400 is a DPF EGR sensor CIRCUIT LOW VOLTAGE detected. most likely is a problem with the wiring to the egr or dpfe sensor. the pinpoint tests for code p1400 instruct you to test all wiring before replaceing the egr or dpfe sensor

Engine light came on in my dodge caravan sxt 3.3L 6cyl. Code P0404. It seems to be running fine, how do I check the EGR valve myself? Any advice would be greatly appreciated.


To check the egr yourself you will need a hand held vacuum pump. To perform the test start the van and let it warm-up, then remove the top vacuum hose from egr valve and attach hand vacuum pump to egr valve. Apply about 5 in-hg vacuum to the egr valve. With the engine at idle speed and vacuum applyed the engine idle speed will drop or stall. If not then the egr valve is faulty and will need to be replaced. If the engine didi change idle speed and or stalled the egr valve is good. Hope this will help you.

Check engine light comes on and off, auto zone test read back EGR flow insufficient/manufact.specif.DTC/see service manual.what does any of that mean?HONDA ACCORD 4CYL.2001


The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. When the EGR valve goes bad, it must be replaced.

The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.

Here is a picture of where the EGR Valve is located (Accord 1999). Replacing it is fairly simple and straightforward. A vacuum line and a couple of bolts. You'll see what you have to do when you look at it.

If you are replacing the EGR Valve due to the Check Engine Light (MIL) being on with a DTC P0401 then I suggest contacting your Honda Dealer. There was a Product Update Campaign (PUD) in the fall of 1999 that corrected the problem.

Another times, the clean is the solution...I hope help yoiu with this. Good luck, and remember rated this help.

EGR code keeps coming on


It may be, but the code will specify what the problem is as a lot of things can trigger an EGR code. There are numerous codes that relate to the EGR, but the individual code will usually pinpoint what the issue is.
Some causes could be the DPFE sensor is faulty; there is a blockage in the EGR (tube), most likely carbon buildup; the EGR valve is faulty; the EGR valve may not be opening due to a lack of vaccuum

01 Ford Expedition. Check Engine light and failed Smog check.


whoever installed the egr valve, if it wasnt you, just cleared the engine codes, thus giving you this problem once again. Get it scanned at autozone, and go from there.

94 camry engine light on, code 71, how do i fix it


Go to Autozone and have your current EGR Valve, removed from the car, tested and they will determine if it is defective. They tested 2 for me, and neither was a replace, just a clean and they worked great. If they don't have a brand that suits your wants, just test it, then buy the new somewhere else, no commitment to buy.
The most common problem with these EGR valves is they get plugged up from carbon build up. Best way to test it is with a little hand held vacuum pump. Hook it up to the EGR valve and with the engine running at idle and squeeze the vacc pump handle a couple times to open the EGR valve. That should kill the engine. If it dosent, the EGR valve is probably plugged up. At that point you'll have to take it off and clean the carbon out. Even if you have your mechanic check into it, it shouldnt be that expensive to remove it and clean it out or replace it.

Good Luck and hope this helps: Oh and I think theres two EGR.. check the one on the bottom of the engine to. I am not sure but i think there are two EGR valves on your camery.
