To find out what's causing the light:
* Obtain a Diagnostic Code: You'll need to get a diagnostic trouble code (DTC). This can be done in a few ways:
* OBD-II Scanner: A 1995 vehicle likely uses an OBD-I system, which requires a scanner specifically designed for that system. OBD-II scanners (common for vehicles from 1996 onward) won't work. Auto parts stores often have OBD-I scanners you can borrow or rent.
* Auto Parts Store: Many auto parts stores will read the code for free. They can then give you a potential diagnosis and parts recommendations. Keep in mind that this is a starting point.
* Mechanic: A mechanic will have the tools and expertise to quickly diagnose the problem. This is often the most reliable (and potentially most expensive) option.
* Common Issues for 1995 Plymouth Voyagers: Some frequent culprits for a "Check Engine" light in this vehicle include:
* Oxygen Sensor: A faulty oxygen sensor impacts fuel efficiency and emissions.
* Mass Airflow Sensor (MAF): This sensor measures the air entering the engine, and a malfunction will affect fuel mixture and performance.
* Throttle Position Sensor (TPS): This sensor tells the computer the throttle position, and a bad one can lead to poor drivability.
* Crankshaft Position Sensor (CKP): Problems with this sensor can prevent the engine from starting or running properly.
* Evaporative Emission System (EVAP) Leak: This system prevents fuel vapors from escaping. A leak can cause the light to illuminate.
Important Note: Ignoring a "Check Engine" light is not recommended. Driving with a problem could lead to further damage to your vehicle, or worse. Get the code read and address the underlying issue as soon as possible.
