Check your gas cap... my check engine light goes on if the gas cap isn't screwed on properly.

I had this issue and there wasn't anything wrong.. take off the battery cables for 5 minutes and then put them back on. If you put it back on and the check engine light doesn't return, it was probably just a sensor wanting you to replace something after a particular mileage. However if you does return, probably need to take it to a mechanic to get reading of the codes, or you can do this with a analog voltage meter.

Warning: unplugging your battery cables will most likely delete all your radio stations... lol

My car is missing need the wireing diagram for a 2003 mitsubishi galant es 2.4 ltr.


From the timing belt to the transmission the fireing orders are 1234 One and three fired the same time 2 and 4 fire the same time. Pull all the plugs for the spark plug on them and lay them across the top of the motor with plugs in them you can see which ones fire at what time. The spark plugs need to be touching a grounded part of the engine to fire. This also will help you find out if you have bad wires.

How do I turn out the check engine soon light on Mitsubishi outla


Hello. The check engine light comes on when the vehicle's computer has detected a problem with one of the components in one of the systems. To find out what exactly that check engine light means you have to hook the vehicle up to a computer scanner. Many auto parts stores now offer this scan for free, as do the AAMCO repair shops. After the scan is finished, the scanner will turn out the check engine light. Some vehicles check engine light also turns off if the battery is disconnected for two full minutes. Regards, Joe

PS kindly rate my answer. Thank you. Joe

2003 MITSUBISHI OUTLANDER AWD, THE RAD. FANS DON'T COME ON WHEN THEY SHOULD. I HAVE PUT NEW CONTROL MUDULE, TEMP. SENDING UNIT, THERMOSTAT AND THEY STILL DON'T WORK. WHEN THE CAR IS RUNNING AND I TAP ON...


Use this thorough testing procedure to troubleshoot this issue.

Step1
Check for broken wires or loose connectors around the fan circuit. Inspect connectors at the fan motor, relay, sensor or heat sensitive switch, and the Electronic Control Module (ECM)--your car’s computer control system. Also, make sure to check for a possible blown fan fuse. These are common and overlooked troublesome spots that may cause a fan to fail.
Step2
Run and bring the engine to warm temperature. With the engine running, use a voltage test light to check for power to the motor fan. Be extra careful and make sure to keep your hands and tools away from the belt, fan or any other engine moving parts. If voltage is reaching the fan motor, the test light should glow.
Step3
Turn off the engine after you see the light glow. Apply direct voltage to the fan motor from your car battery using a pair of spare wires. If the fan fails to operate, replace the fan motor. If the motor operates, your problem is in the motor connector.
Step4
Locate the heat-sensitive switch or heating sensor if the fan motor operates with direct voltage and the test light did not glow. You should find the sensor in the radiator, engine block, or thermostat housing.
Step5
Measure the resistance across the heating sensor with the multimeter. With the engine at cool temperature (engine off), it should register infinite resistance; with the engine at warm temperature (engine off), you should read low resistance. If both readings state infinite resistance install a new heating sensor, that’s the cause of your failing fan.
Step6
Check the action of the fan relay if the heating sensor is registering variable resistance. Your service manual should specify the power and ground wires according to color codes and the proper way to test it. If the fan relay fails the test replace it with a new one.
Step7
Check the connections going to the ECM after you determine the fan relay is working properly. If you find broken wires or loose connectors, make the necessary repairs. If you suspect a defective ECM take your vehicle to a service shop for a computer analysis. In most cases, the ECM is rare to be the cause of a failing fan. The above steps should take you to the root cause of your problem and help you fix the cooler fan.
