How to Identify Defective Dodge Engine Control Module
When your Dodge engine control module goes bad, you are definitely going to go through a really tough way to getting your engine computer system back on track again. Even a replacement is going to be a hard route to take. Because if there's something that is not plausible about ECMs it is that they were designed not to get repaired very easily by just anybody. Special tools and expertise are needed so you can still drive the same Dodge with all its data intact. Early detection through correct troubleshooting will help you make things a little less complicated.
Check engine light never comes off
When the check engine light is constantly on after resetting, your Dodge engine control module is the most probably the cause.
Intermittent start-up is also a symptom of a bad ECM. But you could still look for a dozen of other possible causes of starting problems. Inspect both the ignition and the starting systems.
Stalling and erratic idling
Your car is more likely to act as if there is a terrible internal engine damage that is causing it to stall. Aside from stalling, your Dodge can also go erratic when idling. And you would subsequently try to fix any problem related to such symptoms.
Fuel economy drops
Fuel efficiency will also be greatly affected. But just the same, this problem could be caused by yet another faulty auto part. So inspect and try to eliminate all possible causes.
Power is lost
When your ECM really becomes bad, the engine normally loses power as well because the computer is no longer able to send in the right instructions even for correct firing. The sparks go off and are unable to reach the combustion chamber.
Fuel injection fails
Just as the computer is not able to properly control the sparks, spraying the fuel will fail just the same. No energy is going to be produced to power the vehicle
Car turns off for no reason
There may be times that you could still successfully start the engine of your Dodge, but it suddenly loses power without warning. The apparent reason is that the computer is failing because of a bad Dodge engine control module.
Engine is out
Since the sparks and fuel are both off, your engine is going to be out. If it's not the EMC's fault, the car alternator, battery, starter, or one of the electrical connections could be the culprit. But if all seems fine and still the car just won't start, then the problem that you really are looking at is a faulty ECM.
If you really suspect your engine control module to be problematic, and you're someone who is not automotive savvy, paying a visit to an authorized auto shop is the best option. It is expected to have the latest computer diagnostic equipment for your ECM and will give you only accurate readings about your engine control module. And all you could hope is that it's all good, or else you should prepare for a replacement.
