Guide To P0820 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0820 can be explained Gear Lever X-Y Position Sensor Circuit. The Gear Lever X-Y Position Sensor signal is being monitored by the Transmission Control Module. Now when the Gear Lever X-Y Position Sensor would not be as per the parameters of the manufacturer, then the P0820 trouble code would be set up by the TCM.

Do you want to know more about the P0820 fault code? Don’t worry! Parts Avatar Canada is here at your service. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Gear Lever X-Y Position Sensor Circuit?

• Gear lever X-Y position sensor harness might be opened or shorted
• Malfunctioning gear lever X-Y position sensor
• There can be bad electrical connection in the gear lever X-Y position sensor circuit

1. Crankshaft Position Sensor - A faulty Crankshaft Position Sensor can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Engine Control Module - If everything is alright with Crankshaft Position Sensor, then there is surely some defect in Engine Control Module. Get it replaced before the situation gets worse.
3. Oxygen Sensor - P0820 code can display due to some issues in the Oxygen Sensor. So it is very important to replace the Oxygen Sensor with us at equitable prices.
4. Air Fuel Ratio Sensor - Do you remember when was the last time you got your car Air Fuel Ratio Sensor checked up? A dirty Air Fuel Ratio Sensor can cause a lot of issues like displaying P0820 code.
5. Fuel Temperature Sensor - Poor Fuel Temperature Sensor can cause a lot of difficulties, so why not get it replaced at time?
6. EGR Valve Gasket - Are there some faults in your EGR Valve Gasket? Don’t waste time and get them replaced or else P0820 code can turn up.
7. Powertrain Control Module - OBD Code P0820 can appear because of faulty Powertrain Control Module.
8. Coolant Temperature Sensor - Everything is fine with Powertrain Control Module and still P0820 code triggering? Then you must get your Coolant Temperature Sensor checked.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0820 code to be stored:

You should use a diagnostic scanner, a reliable source of vehicle information, and a digital volt/ohmmeter (DVOM) in order to arrive at an accurate diagnosis of a code P0820. Use the vehicle information source to search for applicable technical service bulletins (TSB). If you locate a TSB that matches the vehicle make and model, symptoms exhibited, and the code stored, it will help you to arrive at a diagnosis. In a lot of vehicles, there is a changeable resistance design of the transmission range sensor. You can find the switch over the transmission shift shaft, where the shift lever slides on over it. Now when there is a movement in the shift lever, the pivot of the range sensor would move to various contacts. Various levels of resistance is sent by switch contacts to the powertrain control module, according to the position of the shift lever. These differing levels of voltage is then interpreted by the PCM as the gear selected by the shifter and utilizes this information to decide shift points, fuel metering, engine ignition timing and a lot of different other functions.

The transmission, engine and ABS inputs is used by the PCM to decide whether the transmission is in the right gear for driving conditions, and then after that the powertrain control module would react on this information. Check the system wiring, connectors and constituents, and then mend/restore any open, shorted, defective or corroded items found, after that the entire system should be retested. If all wiring, connectors and other constituents seem to be in proper working condition, then you should connect the scanner to the diagnostic connector. If there are any stored trouble codes as well as freeze frame data then it should be recorded; this information will be helpful in diagnosing any intermittent conditions that may have consequence in this specific error code. All the codes should be cleared up and the automobile should be taken out for a test drive to see if the code returns. If it is not appearing, then it means that there is an intermittent condition which may need to be allowed to worsen and return so that proper diagnosis can be done. If the code is returning away, then you should check the transmission range sensor for battery voltage/ground signals.

If either ground or battery voltage circuits are open, any related control modules should be disconnected and use the digital volt/ohmmeter to inspect for continuity and resistance in both of the circuits. Restore any system circuits or connectors which are faulty, and then the entire system should be retested. A manufacturer’s wiring schematic should be obtained and test all related circuits and the sensor itself for resistance and continuity. It should be then compared to the manufacturer’s specs. You can always repair and restore any circuits, connectors and constituents that do not comply with manufacturer’s specs. After that you should retest the entire system. Now if you find out that all the circuits comply with manufacturer’s factory specs, then a defective PCM should be suspected but remember that failure in the powertrain control module is very rare and there would be a need of complete reprogramming.
