Fix Your Dodge With Your Own Hands


Here is a rather through discussion of this error message on a 97 ram. I note that this question has been posted on a variety of forums. Perhaps this variation will assist you.

Have u checked the cadeletic converter. It can do funny things

is the check engine light on?

Check the Mass Air Flow Sensor, you can get a can of cleaner specific for cleaning them for a couple bucks at the parts store. I'd just get 1 and clean the sensor see if that works. The MAF sensor is either in the throttle body itself (bolted on from the outside or in the air line between the filter and throttle body. That could be the whole problem right there. Good luck.

Sounds like you need to disconnect the Radiators' electric fans and have them tested. You absolutely must have them working, or your car will overheat. Check to see if the Temperature guage is working.

You need to go to a good autoparts store and have them test the fans and charge and test your battery. You may need some sensors to activate the Radiator fans, but you could be running the battery down with shorted cooling fans.

There are also Relays which work with the Radiator fans. The overflow will stabilize once the water gets into where it belongs. Make sure your Thermostat is not clogged with the sealer.

this is most likely a fuel vapor issue.

fuel boils in the fuel rail causing a hard start after a 'hot soak'.

the fix is to replace the fuel pressure regulator and the pcm. good- day !!

can be injectors leaking when parts is warm and expanded or temp sender not sending correct signals to ecu,so get injectors tested and replace temp sender.hope u succeed.

Anti theft security system. GM's are notorious for it. This link explains it all and gives you some options to fix it yourself... http://vatspasslockpasskeysecurityhelp.yolasite.com/

easy. you have a vacuum leak at the intake manifold. spray some lubricant along the gasket at 5 & 7. should stop missing if leak is on the outside. but if on inside it wouldn't make a difference. I vote to change the intake gasket. I'm having to do the same with a astro van.

po113 is--IAT sensor curcuit high input, po403--egr curcuit flow malfunction. IAT is intake air tempurature curcuit, for egr take off and clean carbon build up from inside of engine to egr valve.
