Question about 2007 Mazda CX-7

1 Answer

Check engine light is on

The EGR valve was replaced 5 months ago. Since that time I have experienced various electrical problems that seemed to correct themselves after a period of time. The driver side control would not work for the passenger side window. Then the control worked, but the window would not stay in the closed position. Then that problem corrected itself. There are lines in the radio display on the dash board. Now the engine light is one again.

Take it back all work has a warranty you should have really taken it back as soon as the problem started explain the situation and tell the you want the job done properly/have you checked the battery lately did they swap it?

Testimonial: "I did call the garage the day after they replaced the EGR valve because the heater would beep when I would turn it on or off, which was not happening before. It was probably supposed to, but that was the first I had heard the on/off indicator since I had the car. The manager checked with the mechanic that worked on my car and he said that the battery had run down while he was working on the car and when that happens everything "resets" itself and it takes some time. The battery is only a few years old. The window problem seemed to correct itself, so I didn't worry too much about it after that. Now the check engine light is on again. I appreciate your input and I am going to call the garage and get the car back in."

    if the manager has stated the machanic had run the battery down sound like the alternator that drives the belt to charge the battery had died bit confused why they left it and diddnt replace repair then defo take it back and ask them to do an investigation tell them about the battery running down as well beacuse if the car is running the battery should (charge itself) if this wasnt happening they should have inspected it

Have you checked the fuel pressure? It sounds like a bad fuel pump.

SOURCE: Passenger window won't work using the driver side control switch

Open the window with the local button and keep the button pressed for 3 seconds after it has fully opened. Then close the window and keep the button pressed for 3 seconds after it has fully closed. This calibrates the position of the window which it lost when you changed the battery. Good luck

Sounds like an EGR valve sticking. Start the engine cold and let it warm up. As soon as it starts to hesitate/stumble, pull the vacuum hose off the EGR and if the engine maintains a steady idle, replace the EGR valve. The EGR is sticking intermittently but it won't be long before it sticks all the time and you won't be able to keep the car running when it gets warm. This is an easy diagnosis, removal and replacement for the do it yourself car owners. Please rate me on my answer.

Truck not firing properly front coil pack not firing at all.


if this truck has an o2 sensor i would replace that and also make sure the cat-converter is not plugged,this would give you your powerloss and egr code,next is your coil,this may be caused by the computer or your crank sensor,look at the tone ring that the crank sensor uses and make sure its not missing teeth or broken,also check all your fuses.

Here is a link for you to check the DTC code to see what issues your engine management has detected. I am going to suspect the EGR valve may be stuck open, that's why your having most of the problem you have described. Good luck and keep me posted and check or replace the EGR valve, the car is too old to just clean out the EGR valve.
