How to Reset the OBD II Codes on a Ford Ranger
Resetting the OBD-II codes on a Ford Ranger is a simple fix that requires no expensive tools. The trucks computer stores trouble codes it detects from sensors placed throughout the vehicle. When it finds a problem, a light illuminates on the instrument panel warning the driver of a problem that needs to be addressed. The vehicles computer also stores codes for routine maintenance. For Ford Rangers that are model year 1996 and later, you can use an OBD-II scanner to read the codes. An OBD-I scanner needs to be used for vehicles 1995 and older. Once the codes have been read by the scanner and the problem fixed, you can reset the codes by disconnecting the battery.
