DTC P0102 &/Or DTC P0103: Notes

Code Definition

DTC P0102: Mass Or Volume Air Flow Circuit Low Input
DTC P0103: Mass Or Volume Air Flow Circuit High Input

NOTE: Intake Air Temperature (IAT) sensor is built into Mass Air Flow (MAF) sensor and they share same harness connector.

NOTE: Before performing any DIAGNOSTIC TEST, refer toWARNINGS, CAUTIONS and NOTES in DIAGNOSTIC TESTS .

NOTE: Testing individual components does not isolate shorts or opens. Perform all voltage tests using a Digital Volt-Ohmmeter Meter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
