P2802 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2802 can be described as Transmission Range Sensor "B" Circuit Low. The error code P2802 would start triggering when the PCM would detect some faults in transmission range sensor "B" circuit. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. The P2802 trouble code would indicate that a transmission range sensor "B" circuit which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination of the malfunction indicator light.

What causes this problem with the Transmission Range Sensor "B" Circuit Low?

• Defaults in the transmission range sensor "B"
• The wiring might be opened or shorted
• Some issues related to the misadjusted transmission range sensor "B"
• There can be inoperative PCM

1. Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
2. Transmission Fluid Pump - Faulty transmission fluid pump can cause harsh shifts and audible transmission noise. This leads to decreased performance and chances of increased physical damage to the transmission components. Thus, replace it immediately.
3. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus, check and replace it, if required.
4. Car Battery - Faulty car battery can have the problem of overheating and fast discharging. Thus, it can affect the motor performance as well as damaged major components. Replace it immediately.
5. Electronic Control Unit - The ECU manages the cooling system to control the battery operating temperatures and thus must be replaced if found faulty. Thus, buy new ECU modules and components from us!
6. Diagnostic Tool - Make use of quality diagnostic tools to resolve any OBD error code. Buy quality diagnostic tools from us!

Here are some steps which you should follow in order to diagnose this fault code:

If you find out that the P2802 error code is triggering, then you might hear a lot of loud noises like explosions, from the rear of the automobile while accelerating. First of all, you must inspect the carburettor to ensure that the fuel and air combination are balanced in the right manner. Now if these settings are right, then you should thoroughly check the distributor cap for any cracks or hairline splits, as this can produce a backfire. Then move on to the spark plugs and ensure that they are perfectly clean and undamaged and then examine the engine gaskets for any sign of damage, as they are responsible for ensuring the right gas exchange within the engine. This error code reports a sensor default and replacement of the sensor is unlikely to resolve the underlying issue. The malfunction is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

Common Mistakes When Diagnosing the P2802 Code

• There can be a failure in the transmission control module
• Defaults in the powertrain control module
• Some issues related to the wiring
• Transmission range sensor failure
