Diagnosis & Repair

WARNING: This page is about a different car, the 2003 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: This DTC uses two-trip detection logic. Using Toyota hand-held tester or scan tool, read FREEZE FRAME data. Freeze frame data records engine conditions when malfunction is detected.

Check for any other DTCs. If other DTCs exist, diagnose and repair those DTCs first and retest. If only DTC P0101 exists, replace MAF meter. MAF meter is bolted to air intake hose, near air cleaner assembly and contains a Black 5-pin electrical connector. For removal and installation of components, see REMOVAL & INSTALLATION - V6 & V8 article.
