If your Dodge RAM 1500 check engine light blink when you accelerate, you might wonder what’s wrong. There are several possible causes for this problem. Let me explain some of them to you.
Possible Causes of the Blinking Check Engine Light
Faulty Wiring Harness or Bad Sensor
First possible cause is faulty wiring harness or bad sensor. Wiring harness connect different parts of your vehicle and can get damaged over time. If sensor is bad, it also cause check engine light to blink.
Internal Fault in a Sensor
Second cause could be internal fault in one of the sensors on your vehicle. If sensor have internal fault, it send wrong signals to other parts, making them not work properly or even fail completely.
Fuel System or Ignition System Issues
Third cause might be related to fuel system or ignition system. Fuel system control how much fuel go into each cylinder, while ignition system control how much power delivered by each spark plug during acceleration.
Engine Computer (ECU) Problems
Fourth cause could be problem with engine computer or ECU (also called powertrain control module, or PCM). ECU control all sensors and components, making them work together to deliver power.
Electrical Short from Damaged Wiring
Fifth cause might be electrical short caused by damaged wiring harnesses or connectors inside engine compartment.
What Should You Do?
If you think your vehicle’s ignition system causing problem, it’s important to take it for test drive. If you feel slight hesitation when accelerating and everything else seem fine, it could be related to engine computer or ECU.
How to Troubleshoot at Home
First thing you can do is check your gas cap. If it’s loose or missing, it can cause problems with fuel pressure, leading to issues with emission systems. Make sure gas cap is tight and not leaking fumes into cabin.
If that not solve issue, check your oil levels and make sure they are within normal levels for your vehicle. Low oil levels can cause issues with getting enough fuel into engine and also cause problems with emissions systems.
If neither of these fix the problem, then it may be time to have your vehicle diagnosed by professional mechanic so they can determine what’s causing this problem before it become more serious than just flashing lights on your dashboard!
Conclusion
Blinking check engine light when accelerating is sign of possible serious problem. While you can try some things at home, it’s best to consult a mechanic to keep your Dodge RAM 1500 safe and running well. Don’t ignore warning; small issues can become big problems if not fixed.
