Signs and Symptoms of B2789 Code in Nissan
The B2789 code in Nissan indicates an issue with the electric compressor being overloaded. This code is usually accompanied by several symptoms that can help you identify the problem. Here are some of the signs and symptoms of the B2789 code in Nissan:
- Check Engine Light: The most common symptom of the B2789 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the vehicle’s engine or emissions system.
- Reduced Performance: Another symptom of the B2789 code is reduced performance of the air conditioning system. The electric compressor may not be able to function properly, resulting in reduced cooling performance.
- Strange Noises: If the electric compressor is overloaded, it may produce strange noises. You may hear a grinding or whining sound coming from the engine compartment.
- Difficulty Starting: In some cases, the B2789 code may cause difficulty starting the engine. This is because the electric compressor is putting too much strain on the battery and starter motor.
- Increased Fuel Consumption: If the electric compressor is overloaded, it may cause the engine to consume more fuel than usual. This is because the engine has to work harder to compensate for the compressor’s inefficiency.
If you notice any of these symptoms in your Nissan, it is important to have the vehicle inspected by a qualified mechanic.

Ignoring the B2789 code can lead to further damage to the vehicle’s engine and emissions system, resulting in costly repairs down the line.
Possible Causes of B2789 Code in Nissan
The B2789 code in Nissan indicates an issue with the electric compressor being overloaded. This code is usually triggered when the compressor is drawing too much power or when there is a problem with the compressor clutch. Here are some of the possible causes of the B2789 code:
- Faulty electric compressor clutch: The electric compressor clutch is responsible for engaging and disengaging the compressor. If the clutch is faulty, it may not be able to engage or disengage the compressor properly, leading to an overload.
- Low refrigerant level: The refrigerant is responsible for cooling the air in the car. If the refrigerant level is low, the compressor may have to work harder to cool the air, leading to an overload.
- Faulty compressor: If the compressor itself is faulty, it may draw too much power and overload the system.
- Electrical issues: There may be an issue with the electrical system that is causing the compressor to draw too much power. This could be due to a faulty relay, wiring issue, or other electrical problem.
- Software issues: In some cases, the B2789 code may be triggered due to a software issue in the car’s computer system. This could be due to a glitch or bug in the software.
If you are experiencing the B2789 code in your Nissan, it is important to have it diagnosed and repaired as soon as possible. Continuing to drive with an overloaded compressor can cause further damage to the system and lead to more expensive repairs down the line. A qualified mechanic can diagnose the issue and recommend the best course of action to fix it.
