Investigating the P0100 Code on Your 2024 Infiniti QX60
A P0100 code on your 2024 Infiniti QX60 signals a mass air flow sensor circuit malfunction in the 3.5L V6 engine. Under Infiniti's full warranty coverage, this should be diagnosed and repaired at no cost at your dealer.
New QX60 Context
The 2024 QX60's VQ35DD V6 is a proven design. A P0100 on a new QX60 is most likely related to a connector issue, software calibration, or isolated component defect rather than wear. The naturally aspirated engine keeps the diagnosis straightforward.
Prime Suspects in This Investigation
- Loose MAF connector (30%) — A connector not fully engaged during assembly.
- ECM software calibration (25%) — Nissan/Infiniti may have a software update for MAF parameters.
- Intake assembly issue (20%) — A loose duct clamp or connection from the factory.
- Defective MAF sensor (15%) — A manufacturing defect in the sensor element.
- Wiring issue (10%) — A pinched or improperly routed wire.
What to Do
- Check the MAF connector is fully seated.
- Schedule an Infiniti dealer appointment mentioning P0100.
- The dealer will use CONSULT to diagnose and repair under warranty.
