Owners of 2022-2023 Nissan Sentra vehicles may encounter a specific set of symptoms related to the vehicle's electrical and charging system. Nissan Technical Service Bulletin (TSB) NTB22-096A provides diagnostic and repair procedures for these issues.
Symptoms
If you own a 2022-2023 Nissan Sentra, you might experience one or more of the following:
- "Loss of electrical power"
- "Loud noise from the front of vehicle/engine area while running"
- "The battery light is ON"
These symptoms are often accompanied by confirmation that the loud noise, if present, is originating from the generator (alternator).
Diagnosis and Trigger Conditions
Technicians are instructed to confirm the presence of the described symptoms. A key diagnostic step is to verify that any audible noise is indeed coming from the alternator. This helps to pinpoint the source of the problem before proceeding with repairs.
Repair Procedure Summary
To resolve these issues, the TSB outlines a specific repair action. The procedure involves replacing three key components within the charging system:
- Alternator: The primary component responsible for generating electrical power.
- Drive Belt Auto Tensioner: This component maintains proper tension on the drive belt.
- Associated Drive Belt: The belt that connects the alternator and other accessories to the engine.
The repair process requires referring to the Electronic Service Manual (ESM) for detailed instructions on the removal and installation of the generator (alternator) and the drive belt auto tensioner. Specifically, technicians will consult the "ELECTRICAL & POWER CONTROL > CHARGING SYSTEM > REMOVAL AND INSTALLATION > GENERATOR" and "ENGINE > ENGINE MECHANICAL > MR20DD > REMOVAL AND INSTALLATION > DRIVE BELT AUTO TENSIONER" sections. Figure 1 in the TSB illustrates the location of these components on the MR20DD engine.
Required Tools or Parts
The following parts are required for this repair:
| DESCRIPTION | PART NUMBER | QUANTITY |
|---|---|---|
| TEN-PULLEY (Drive Belt Auto Tensioner) | 11955-5TA0B | 1 |
| Alternator | 23100-6LB0A | 1 |
| Drive Belt | 11720-5TA0B | 1 |
For warranty claims, the Alternator (part number 23100-*****) should be designated as the Primary Failed Part (PFP) with OP CODE GX34AA, SYM ZL, DIA 32, and FRT 2.6.
