Your first order of business is to check the oil level in the crankcase, and bring it up to full level. You can probably find a replacement dip stick, or go to a junkyard and get one. Without sufficient oil in the engine, The will seize. or prematurely die. Is your check oil light coming on? Have the car scanned for trouble codes. Auto Zone and Advance Auto will a scan.

That's a tricky one. Sounds as though there may be a loose connection / dodgy fuse or even a charging fault. I assume the battery lamp is not glowing at all when the engine is running.

Hi I'm Peter your code P0720 Output Speed Sensor Circuit Malfunction This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. On electronically controlled transmissions, the Output Shaft Speed Sensor (OSS) is located on the end of the transmission before the drive axles or driveshaft to read the speed of the output shaft which may be used to determine shift scheduling, torque converter engagement schedule and Electronic Pressure Control (EPC) inside the transmission. The Powertrain control module / Engine control module (PCM/ECM) has determined there is a malfunction with the OSS sensor. The PCM/ECM may substitute values based on other sensors to determine shift timing, torque converter operation and EPC pressure if the OSS sensor information is unavailable. The OSS sensor is also commonly used for the speedometer. Note: On some vehicles, the OSS sensor is inline with the Transmission Fluid Temperature (TFT) sensor, if there is a failure with the TFT sensor or associated wiring, the OSS sensor may malfunction as well. If there is another code associated with the TFT sensor as well as the OSS sensor, suspect a possible problem with either sensor, or the wiring in between
