P0102 2004 Infiniti G35 Code - Mass or Volume Air Flow Circuit Low Input

Symptoms may include a lack of power, rough idling, stalling, poor fuel efficiency, and possibly even a Check Engine light.

This code indicates that the Engine Control Module (ECM) has detected a lower than expected voltage from the Mass Air Flow (MAF) sensor.

Common causes include a faulty MAF sensor, a dirty or contaminated MAF sensor, a vacuum leak, damaged intake air duct, or issues with the wiring or connectors.

Diagnosis typically involves checking the MAF sensor for dirt or debris, inspecting the air intake system for leaks, testing the sensor's voltage output, and examining the wiring and connectors for any damage.

Yes, a dirty or clogged air filter can disrupt the airflow to the MAF sensor, leading to inaccurate readings and potentially triggering the P0102 code.

Try cleaning the MAF sensor with MAF sensor cleaner, inspect and replace the air filter if necessary, check for vacuum leaks, and ensure all connections are secure.

It is not recommended to drive with this code unresolved, as it can lead to poor engine performance and potentially cause further damage if left unattended.

Resetting the ECM may temporarily clear the code, but if the underlying issue causing the code is not addressed, it is likely to reappear once the ECM detects the problem again.

The cost of repair can vary depending on the exact cause of the code, but it could range from a simple DIY fix with cleaner to a more involved repair involving sensor replacement or professional diagnostics.

While a faulty O2 sensor is not a common cause of P0102, it can contribute to incorrect air/fuel mixture readings, which may indirectly affect the MAF sensor and trigger the code.
