Code Definition

1. DTC P0101: Mass Or Volume Air Flow Circuit Range/Performance Malfunction
2. DTC P0102: Mass Or Volume Air Flow Circuit Low Input
3. DTC P0103: Mass Or Volume Air Flow Circuit High Input

Note. Before performing any diagnostic test, refer to WARNINGS, 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.

Diagnostic Aids

Engine Control Module (ECM) continuously monitors MAF sensor output. ECM will set code sensor output voltage has continued to be 4.5 volts or higher for 4 seconds. Check for following possible problems

1. Open between MAF sensor and Main relay.
2. Open or short between MAF sensor and ECM.
3. Short between MAF sensor and ECM harness.
4. Dirty air cleaner.
5. Air leak in intake system.
6. Contaminated, deteriorated or damaged MAF sensor.
