Question about 2005 Ford Explorer

2 Answers

"check system charging" is coming on at high RPM's

Our Explorer is having what seems to be a slight miss during idle and when hitting high RPM's the "check system charging" and "battery" light starts flashing until you let off the gas. Also about 3 months ago I replaced the battery because it was dead one morning.

I have a 2005 explorer with the same problem. It started when I hit 5 rpm at first and then it starting going off constantly. I had the battery replaced and then shortly after the alternator replaced. A year and a half after that it happened again. The battery gage does not change and lights do not go deem. I took it to a different garage and was told this is a known problem for explorers and expeditions and it could either be the sensor located in the alternator go bad or the computer board. I have choosen to not replace anything and have not had any problems other than the check charging system going off on an occasions.

Toyota Rav 4 1997 .Check engine comes on .Codes are P0301,302,303,304116 . What to do.


The engine coolant temperature is high. Your other Codes are for missing cylinders on cylinder 1,2,3,and 4. Get the Codes cleared and start over. Changing the plugs and wires,etc could have generated the missing cylinder Codes.

Check your engine for an IDLE SPEED CONTROL SOLENOID, which may be in the intake. Or a fuel pressure regulator.

A lot of times people work on the spark side and forget the fuel injectors. They can cause a miss.

look for a site glass on the small high pressure line.This will be helpful when you charge the system. Charge the system at a fast idle or slightly above 1200 to 1400 rpm.As you charge you will see bubbles in the glass and a fommy look to the freeon as you charge the A/C It will start to cool even before the bubbles go away. Keep charging untill the site glass clears up! Stop as soon as there are no more bubbles seen.This is the best way i know how for you to charge the system and not check the high side pressures as you charge.

The P0420 code is a Catalytic converter efficiency code check the compression.Swap the #1 injector to a different location to see if the code follows.Test the coilpak. A cracked exhaust manifold is the most likely cause p0171 and 0174 Induction air leaks, vacuum or some kind fuel restriction, weak fuel pump, restricted fuel filter etc.You also could have an exhaust leak near the upstream o2 sensor. If youtake it in they will probably use smoke to find out where the leak is.
