Nissan & Infiniti 3.7 litre V6, Top 10 Misunderstood Engine Sensors: OBD4Everyone Ep.17

In the title I used the term “engine sensor” however, I am actually going to explain 10 misunderstood parameter IDs or PIDs.

These PIDs are provided by the engine’s onboard diagnostic system and we will be looking at a service called Mode $01, which shows us live data.

The $ in mode $01 tells us it is a hexadecimal number. Google hexadecimal if you want to know more, but you don’t need to for the purpose of this video.

We are going to be using a portion of OBD Fusion’s Diagnostic report to look at the TOP TEN mode $01 PIDs for Nissan’s 3.7 litre v6 engine known as the VQ37VHR:

Top Ten Misunderstood Mode $01 PIDs for the VQ37VHR

• Fuel system status for bank 1 and bank 2
• Calculated load • Short/Long Fuel trims for bank 1 and bank 2
• Intake Manifold absolute pressure (MAP)
• Intake air temp (IAT) • O2 Sensor lambda for bank 1 and bank 2
• Barometric pressure
• Absolute Load
• Accelerator Pedal position D&E
• Mass airflow for bank 1 and bank 2 (MAF A/B)

Please keep in mind, the typical values provided may be different than yours for many reasons like elevation, air temperature, and gasoline quality just to name a few.
