Investigating the P0100 Code on Your 2023 Nissan Murano
A P0100 code on your 2023 Nissan Murano indicates the ECM has detected a malfunction in the Mass Air Flow (MAF) sensor circuit. As one of the final model years for the 3rd-generation Murano, your crossover's 3.5L V6 relies on precise MAF data for fuel delivery and CVT management. Your vehicle should still be under factory warranty, making the dealer your first stop.
MAF System on the 2023 Murano
The 2023 Murano uses the VQ35DE 3.5L V6 (260 hp) with a CVT. The hot-wire MAF sensor measures incoming air mass for fuel injection, ignition timing, and transmission ratio calculations. P0100 indicates the circuit is producing signals outside the ECM's expected voltage range.
Symptoms
- Check engine light on with P0100
- Hesitation during acceleration
- Rough idle
- Reduced fuel economy
- CVT may feel unresponsive or erratic
- Possible reduced power mode
Common Causes
- Contaminated MAF sensor element (30-35%) — PCV oil vapor deposits even on newer vehicles.
- Air intake leak (20-25%) — Loose connections or improperly seated air filter.
- MAF sensor or circuit defect (20-25%) — Manufacturing defect or early failure—warranty claim territory.
- Software calibration issue (10-15%) — ECM updates may be available.
- Connector or wiring fault (5-10%) — Assembly-related issues.
Warranty-First Approach
Your 2023 Murano is covered under Nissan's 3-year/36,000-mile basic warranty through approximately 2026, and the 8-year/80,000-mile federal emissions warranty through 2031:
- Document symptoms — Record when the light appeared and any performance changes.
- Contact your Nissan dealer — Schedule warranty service mentioning P0100.
- Request TSB check — Ask the technician to check for applicable Technical Service Bulletins.
- Keep records — Save repair documentation.
