It doesn't have OBDII, I think that's why you can't find it. You can check the code by turning the key on and off 3 times within 5 seconds. The code will flash at you using the "check engine light". Long pauses in between indicate flashes seperates the different codes.

To reset the "Service Engine Soon" light in a 1999 Plymouth Voyager, you can disconnect the battery by removing the negative terminal for about 15 minutes. After reconnecting the terminal, the light should reset. Alternatively, you can use an OBD-II scanner to clear the trouble codes, which will also turn off the light. However, ensure that any underlying issues are addressed before resetting the light to avoid potential engine problems.

To use the On-Board Diagnostics (OBD) system on a 1989 Plymouth Voyager, you typically need to connect an OBD-I scanner to the diagnostic connector, which is usually located under the dashboard near the driver's seat. The scanner will read any trouble codes stored in the vehicle's computer, which can help diagnose issues with the engine or other systems. After connecting the scanner, follow the manufacturer's instructions to retrieve and interpret the codes. Keep in mind that OBD-I systems may have limited functionality compared to newer OBD-II systems.
