Details of the Isuzu p0102 OBD Code

P0102 fault code on Isuzu indicates a low voltage signal from the mass airflow sensor.

OBD code P0102 for Isuzu vehicles indicates an issue with the Mass Air Flow (MAF) sensor circuit.

This code is triggered when the ECM detects a low voltage signal from the MAF sensor.

The MAF sensor measures the amount of air entering the engine to calculate the correct air/fuel mixture for combustion.

When the voltage signal is lower than expected, it can lead to drivability issues like poor acceleration, rough idling, or stalling.

The ECM triggers this code based on the input it receives from the MAF sensor, indicating a potential problem with the sensor itself, the wiring, or the connector.

Mechanic’s Tech Notes

For Isuzu P0102, check the MAF sensor circuit for low voltage issues causing the fault code.

To diagnose and fix OBDII code P0102 on an Isuzu, start by checking the power and ground to the Mass Air Flow (MAF) sensor using a voltmeter.

Ensure the sensor is receiving proper voltage.

Next, inspect the MAF sensor wiring harness and connector for any damage, corrosion, or loose connections.

Use a scan tool to monitor MAF sensor data while the engine is running to see if it is within specifications.

If the sensor readings are out of range, consider replacing the MAF sensor.

Additionally, check for any air leaks in the intake system that could affect sensor readings.
